Chris@2484 1
Chris@2484 2 Changes in Sonic Visualiser v4.1 (April 2020) since the previous release 4.0.1:
Chris@2484 3
Chris@2484 4 - Support "dark mode" on Windows and Linux as well as macOS
Chris@2484 5
Chris@2484 6 - Add right-click (or Ctrl-click, on the Mac) context menus to the
Chris@2484 7 layer property tabs, pane zoom controls, and all dial controls,
Chris@2484 8 providing some basic edit and reset functions
Chris@2484 9
Chris@2484 10 - Provide format options when exporting layers to CSV, allowing
Chris@2484 11 control over column separator, header row, and timestamp forma
Chris@2484 12
Chris@2484 13 - Add export of spectrogram data to CSV formats
Chris@2484 14
Chris@2484 15 - Fix missing undo/redo of layer renames
Chris@2484 16
Chris@2421 17
Chris@2430 18 Changes in Sonic Visualiser v4.0.1 (10 Dec 2019) since the previous release 4.0:
Chris@2421 19
Chris@2421 20 - Fix nonsense vertical scale in NoteLayer when displaying a model
Chris@2421 21 with non-Hz scale (e.g. from an analysis plugin that outputs MIDI
Chris@2421 22 note values)
Chris@2421 23
Chris@2421 24 - Fix failure to open playback device when using macOS Catalina with
Chris@2421 25 certain audio devices
Chris@2421 26
Chris@2421 27 - Fix failure to make installed executables executable when
Chris@2423 28 compiling and installing the source package
Chris@2421 29
Chris@2211 30
Chris@2403 31 Changes in Sonic Visualiser v4.0 (25 Oct 2019) since the previous release 3.3:
Chris@2328 32
Chris@2335 33 - Add Box annotation layer type, typically used for time-frequency
Chris@2335 34 boxes to be annotated over a spectrogram. Because this introduces a
Chris@2335 35 new layer type into the session file format, the major version
Chris@2383 36 number has been bumped to v4.0. Sessions saved from v4.0 can still
Chris@2383 37 be opened in earlier versions of Sonic Visualiser, but any Box
Chris@2383 38 layers will not be loaded
Chris@2383 39
Chris@2383 40 - Fix behaviour of auto-align layers on top of waveform: they can now
Chris@2383 41 be aligned in the vertical scale, if they have a unit of V and the
Chris@2383 42 waveform is of a single channel in linear or dB mode
Chris@2383 43
Chris@2383 44 - Make the UI more readable in macOS "dark mode"
Chris@2383 45
Chris@2383 46 - Fix sluggishness in starting and stopping playback when using
Chris@2383 47 PulseAudio v13.0+
Chris@2335 48
Chris@2328 49
Chris@2345 50 Changes in Sonic Visualiser v3.3 (21 May 2019) since the previous release 3.2.1:
Chris@2211 51
Chris@2211 52 - Add support for reading the Opus audio codec on all platforms
Chris@2211 53
Chris@2211 54 - Add support for WMA and AAC formats on 64-bit Windows. (AAC was
Chris@2211 55 already supported on macOS.) Note that AAC support on Windows does
Chris@2211 56 not support "gapless" import, i.e. removing the encoder gaps at
Chris@2211 57 start and end of the stream
Chris@2211 58
Chris@2260 59 - Add ability to choose the field separator when importing CSV and
Chris@2260 60 CSV-like files, if more than one possible candidate separator is
Chris@2260 61 found in the file
Chris@2260 62
Chris@2260 63 - Fix crash when closing session or starting a new session while
Chris@2260 64 calculating alignment of multiple audio files
Chris@2260 65
Chris@2260 66 - Fix crash when running certain plugins that call for
Chris@2260 67 frequency-domain input at non-power-of-two block sizes
Chris@2260 68
Chris@2260 69 - Fix wandering left edge of measure-tool rectangle while dragging
Chris@2260 70 out the area
Chris@2260 71
Chris@2260 72 - Ensure that plugin stderr debug output is logged to the SV log file
Chris@2260 73
Chris@2002 74
Chris@2345 75 Changes in Sonic Visualiser 3.2.1 (07 Jan 2019) since the previous release 3.2:
Chris@2175 76
Chris@2175 77 - Fix failure to record from built-in microphone on macOS 10.14
Chris@2175 78 (caused by lack of microphone permission request text)
Chris@2175 79
Chris@2175 80 - Fix crash when closing SV or starting a new session during recording
Chris@2175 81
Chris@2175 82 - Fix crash on exit in some builds that disable OSC support
Chris@2175 83
Chris@2175 84 - Fix flashing effect when scrolling certain configurations of colour 3d
Chris@2175 85 plot layer leftwards
Chris@2175 86
Chris@2175 87
Chris@2345 88 Changes in Sonic Visualiser 3.2 (07 Dec 2018) since the previous release 3.1.1:
Chris@2002 89
Chris@2048 90 - Add ability to zoom closer than one sample per pixel, so as to see
Chris@2048 91 the interpolated signal level between samples
Chris@2048 92
Chris@2110 93 - Add oversampling control to the spectrogram and spectrum layers
Chris@2110 94
Chris@2110 95 - Highlight and label frequency peaks in the spectrum as the mouse
Chris@2110 96 rolls over them, when enabled in the parameter area
Chris@2110 97
Chris@2002 98 - Add feature to convert and import audio from a CSV data file
Chris@2002 99
Chris@2048 100 - Add some new colour maps, and restore the old Blue on Black one
Chris@2048 101
Chris@2110 102 - Speed up spectrum rendering at high resolutions
Chris@2110 103
Chris@2048 104 - Fix failure to pass Nyquist bins correctly to
Chris@2048 105 frequency-domain-input Vamp plugins in some circumstances
Chris@2048 106
Chris@2110 107 - Fix sometimes incorrect shortcut associations for new-layer menu
Chris@2110 108 items
Chris@2110 109
Chris@2139 110 - Various other rendering improvements and bug fixes
Chris@2110 111
cannam@1948 112
Chris@2345 113 Changes in Sonic Visualiser 3.1.1 (14 Aug 2018) since the previous release 3.1:
cannam@1948 114
cannam@1948 115 - Fix failure to record correctly into an empty session with certain
cannam@1948 116 audio drivers
cannam@1948 117
Chris@1958 118 - Fix failure to run LADSPA plugins at all, except with some unusual
Chris@1958 119 path layouts
Chris@1958 120
Chris@1958 121 - Fix failure to silence sonified notes when rewinding backwards or
Chris@1958 122 jumping back from a loop endpoint
Chris@1958 123
cannam@1948 124 - Fix macOS .dmg image so as to use older HFS+ filesystem for compatibility
cannam@1948 125
Chris@1871 126
Chris@2345 127 Changes in Sonic Visualiser 3.1 (14 July 2018) since the previous release 3.0.3:
Chris@1871 128
Chris@1871 129 - Add Plugins tab to Preferences dialog, from which you can review
Chris@1871 130 the plugin load paths and see which plugins were loaded from which
Chris@1871 131 locations, and also customise load paths (though the various path
Chris@1871 132 environment variables are still supported)
Chris@1871 133
Chris@1935 134 - Stream the export of audio data and other CSV data so that
Chris@1935 135 very large exports don't hang the UI or run us out of memory
Chris@1935 136 (thanks to Lucas Thompson)
Chris@1935 137
Chris@1935 138 - Ensure vertical scale appears for auto-align layers when there is
Chris@1935 139 nothing else to auto-align them to
Chris@1935 140
Chris@1871 141 - Fix another long-standing Windows-platform wide-char/utf8
Chris@1871 142 conversion problem, with environment variable naming and contents
Chris@1871 143
Chris@1871 144 - Improve handling of incomplete session loads, i.e. situations where
Chris@1871 145 the audio files referred to by a session could not be found -
Chris@1871 146 previously the session could be re-saved immediately thus losing
Chris@1871 147 the audio reference; now at least we disable Save (enabling only
Chris@1871 148 Save As) and show a warning
Chris@1871 149
Chris@1871 150 - Update pane and layer menu shortcuts so that the
Chris@1871 151 waveform/spectrogram/etc shortcuts (Shift+G etc) operate on the
Chris@1871 152 source model in the currently-selected pane rather than the main
Chris@1871 153 model. This is a backward-incompatible change but is a far more
Chris@1871 154 intuitive way for the function to work
Chris@1871 155
Chris@1935 156 - Use dark background for bright colours in time-value/note/etc
Chris@1935 157 layers as well as e.g. waveforms - this is how it was always
Chris@1935 158 "intended to" work, but it is a backward-incompatible change
Chris@1935 159
Chris@1871 160 - Make "Select All" select the whole span of everything that exists,
Chris@1871 161 not just the main model
Chris@1871 162
Chris@1871 163 - Add horizontal scale to Spectrum layer
Chris@1871 164
Chris@1871 165 - Improve spacing and labelling of vertical log scales
Chris@1871 166
Chris@1871 167 - Update build system for better Cap'n Proto version support and to
Chris@1871 168 use Repoint for code management in the repository
Chris@1871 169
Chris@1871 170 - Various other bug fixes
Chris@1871 171
Chris@1702 172
Chris@2345 173 Changes in Sonic Visualiser 3.0.3 (25 May 2017) since the previous release 3.0.2:
Chris@1702 174
Chris@1702 175 - Improve decisions about where and how to label vertical scales
Chris@1702 176
Chris@1702 177 - Update build support material and documentation to reflect the
Chris@1702 178 official release of Cap'n Proto 0.6 (which we can now use rather
Chris@1702 179 than depending on git builds)
Chris@1702 180
Chris@1669 181
Chris@2345 182 Changes in Sonic Visualiser 3.0.2 (25 Mar 2017) since the previous release 3.0.1:
Chris@1669 183
Chris@1669 184 - Fix crash when changing parameters for spectrum view
Chris@1669 185
Chris@1669 186 - Fix incorrect measure tool crosshairs in spectrum view
Chris@1669 187
Chris@1669 188 - Update Russian and Czech UI translations (thanks to Alexandre Prokoudine
Chris@1669 189 and Pavel Fric respectively)
Chris@1702 190
Chris@1658 191
Chris@2345 192 Changes in Sonic Visualiser 3.0.1 (12 Mar 2017) since the previous release 3.0:
Chris@1658 193
Chris@1658 194 - Fix crashes with MIDI devices and speedup/slowdown control on Windows
Chris@1661 195
Chris@1658 196 - Update MIDI input driver layer
Chris@1447 197
Chris@1661 198
Chris@2345 199 Changes in Sonic Visualiser 3.0 (07 Mar 2017) since the previous release 2.5:
Chris@1447 200
Chris@1516 201 - Add ability to record audio, and ability to change the audio device
Chris@1516 202 for playback or recording in the preferences
Chris@1447 203
Chris@1447 204 - Add complete support for high-resolution (Hi-DPI or retina)
Chris@1511 205 displays, including for layer data rendering as well as UI controls
Chris@1511 206 and icons. This makes the biggest difference when using a retina
Chris@1511 207 Mac, on which previous versions did not render layer data at retina
Chris@1447 208 resolution, but it also improves scaling and rendering of UI
Chris@1447 209 elements on Hi-DPI displays on Windows and Linux
Chris@1447 210
Chris@1451 211 - Add ability to export scalable (SVG) image files
Chris@1451 212
Chris@1447 213 - Run plugins in a separate process, so that if a plugin crashes, it
Chris@1447 214 no longer brings down Sonic Visualiser with it. In every other
Chris@1447 215 respect the behaviour should be unchanged
Chris@1447 216
Chris@1447 217 - Scan plugins on startup in a separate process, and report on any
Chris@1447 218 that crash or won't load
Chris@1447 219
Chris@1527 220 - Add ability to open, display, and analyse very long audio files (of
Chris@1527 221 more than 2^32 sample frames)
Chris@1527 222
Chris@1447 223 - Change mp3 file loading so as to compensate for encoder/decoder
Chris@1447 224 delay and padding (using "gapless playback" logic). While this is a
Chris@1447 225 real improvement, unfortunately it does mean that the initial
Chris@1447 226 padding in mp3 file load has changed from previous versions, which
Chris@1447 227 may mean some sessions saved in previous versions are no longer
Chris@1447 228 correctly aligned. It's not a great idea to use mp3 as a file
Chris@1447 229 format of record, because of differences like this between
Chris@1447 230 decoders. The previous behaviour is still available as a preference.
Chris@1447 231
Chris@1470 232 - Add new Hybrid normalisation type for spectrogram and colour 3d
Chris@1470 233 plot layers. This normalises each column to its peak value and then
Chris@1470 234 scales the normalised values by the log of the peak in order to
Chris@1470 235 restore some distinction in scale between columns with different
Chris@1470 236 levels. It can provide quite visually clear results.
Chris@1470 237
Chris@1447 238 - Add function to subdivide time instant layers into regular
Chris@1447 239 intervals (and its inverse)
Chris@1447 240
Chris@1447 241 - Add new preference for default colour scales
Chris@1447 242
Chris@1578 243 - Add a basic ability to zoom (in the frequency axis) to the spectrum
Chris@1624 244
Chris@1447 245 - Switch to using combined level/pan controls in layer property boxes
Chris@1447 246 and for the main volume control
Chris@1447 247
Chris@1520 248 - Make CSV file reader better able to handle files with varying
Chris@1520 249 numbers of columns
Chris@1520 250
Chris@1516 251 - Fix a number of problems on Windows with loading and saving some
Chris@1516 252 file formats to filenames not representable in system codepage
Chris@1516 253
Chris@1520 254 - Add "What's New" dialog
Chris@1520 255
Chris@1527 256 - Finally switch the Windows build to 64-bit by default (with
Chris@1447 257 adapters to run either 32- or 64-bit plugins)
Chris@1451 258
Chris@1447 259
Chris@2345 260 Changes in Sonic Visualiser 2.5 (23 Oct 2015) since the previous release 2.4.1:
Chris@1072 261
Chris@1072 262 - Add unit-converter dialog, for converting between various pitch and
Chris@1072 263 timing units
Chris@1072 264
Chris@1072 265 - Fix failure to reload note layers from session file
Chris@1072 266
Chris@1072 267 - Use a more sensible scale for the play-speed dial
Chris@1072 268
Chris@1072 269 - Fix crash when importing very wide CSV files
Chris@1072 270
Chris@1072 271 - Fix generation of wrong layer type from some CSV files
Chris@1072 272
Chris@1072 273 - Fix failure to export last instant in a time-instant layer
Chris@1072 274
Chris@1457 275
Chris@2345 276 Changes in Sonic Visualiser 2.4.1 (01 Oct 2014) since the previous release 2.4:
Chris@876 277
Chris@876 278 - Fix a crash when rendering certain colour 3d plot layers
Chris@716 279
Chris@1457 280
Chris@2345 281 Changes in Sonic Visualiser 2.4 (01 Sep 2014) since the previous release 2.3:
Chris@714 282
Chris@776 283 - Add support for left/right scrolling using a two-finger touchpad
Chris@776 284 gesture (where available)
Chris@776 285
Chris@716 286 - Make the octave numbering into a configurable option, and change
Chris@716 287 the default. Previously Sonic Visualiser labelled middle-C as "C3";
Chris@716 288 now it labels middle-C as "C4", a more common standard in the world
Chris@776 289 outside MIDI sequencer software. The previous system is available
Chris@776 290 as an option in the Preferences. This affects only the visible
Chris@776 291 labels: there is no change to analysis or to the file format
Chris@714 292
Chris@714 293 - Sonify time-value layers. Any time-value curve whose scale unit is
Chris@714 294 set to Hz will now acquire a playback toggle control; this control
Chris@714 295 is off by default, but if it is switched on, the curve will be
Chris@714 296 played back using a variable-frequency sound generator
Chris@714 297
Chris@714 298 - Add support for playback of note layers with non-MIDI frequencies
Chris@714 299 (formerly the note playback was limited to exact MIDI pitch)
Chris@714 300
Chris@714 301 - Change the default playback sample for note layers from piano to an
Chris@714 302 electric piano with sustain. The piano sample is still available,
Chris@714 303 and any sessions saved using it should continue to use it
Chris@714 304
Chris@867 305 - Add a cancel button for Vamp plugin processing: currently,
Chris@867 306 cancelling a transform results in a part-complete layer rather than
Chris@867 307 removing the results
Chris@867 308
Chris@790 309 - Add keyboard shortcuts to cycle the current layer (in addition to
Chris@790 310 the existing ones to cycle the current pane)
Chris@790 311
Chris@790 312 - Fix various bugs related to layer ordering: layer tabs re-ordering
Chris@790 313 themselves randomly when new layer added, layers being ordered
Chris@791 314 randomly when saving and reloading a session
Chris@790 315
Chris@848 316 - Fix incorrect interaction with non-Unicode usernames when creating
Chris@848 317 temporary and template directories on Windows
Chris@848 318
Chris@714 319 - Shade the start and end of the main audio file, to make them easier
Chris@714 320 to see for files that start or end in silence
Chris@714 321
Chris@714 322 - Speed up rendering and scrolling in time-value layers
Chris@714 323
Chris@714 324 - Make it possible to import CSV files directly into Note layers by
Chris@714 325 adding Pitch as a data type in the CSV file import dialog
Chris@675 326
Chris@856 327 - Fix play pointer jump to wrong frame when clicking on row in the
Chris@856 328 layer edit dialog
Chris@856 329
Chris@848 330 - Fix problems with keyboard shortcuts when using Qt5 on OS/X. This
Chris@848 331 is the first release in which the official builds use Qt5 for all
Chris@848 332 platforms.
Chris@848 333
Chris@675 334
Chris@2345 335 Changes in Sonic Visualiser 2.3 (12 Dec 2013) since the previous release 2.2:
Chris@675 336
Chris@675 337 - Add a startup welcome dialog that also explains what SV makes
Chris@675 338 network connections for and allows user to forbid them
Chris@675 339
Chris@675 340 - Add "Export Audio Data" feature
Chris@675 341
Chris@675 342 - Show piano keyboard scale in note and time-value layers as well
Chris@675 343 as spectrogram, where vertical scale is log Hz; also show
Chris@675 344 numerical scale in note and region layers when not auto-aligned
Chris@675 345
Chris@675 346 - Speed up CSV file import and avoid showing crazily wide window
Chris@675 347 for CSV file format dialog when file has lots of columns
Chris@675 348
Chris@675 349 - Fix incorrectly saved window geometry when exiting from maximised
Chris@675 350 state
Chris@675 351
Chris@675 352 - Reduce number of timer wakeups when idle
Chris@675 353
Chris@675 354 - Add American English translation and make choice of translation
Chris@675 355 into a preference (defaulting to system locale)
Chris@675 356
Chris@675 357 - Permit installation to non-default location with Windows installer
Chris@675 358 build
Chris@714 359
Chris@608 360
Chris@2345 361 Changes in Sonic Visualiser 2.2 (31 July 2013) since the previous release 2.1:
Chris@608 362
Chris@608 363 - Build with support for hidpi ("retina") text on OS/X
Chris@675 364
Chris@608 365 - Fix very slow analysis when using Ogg or FLAC files decoded
Chris@608 366 via libsndfile
Chris@675 367
Chris@608 368 - Fix inaccurate scale auto-align between time-value layers and
Chris@608 369 others
Chris@675 370
Chris@608 371 - Fix failure to open files specified on command line (or via
Chris@608 372 Open With) on Windows
Chris@675 373
Chris@608 374 - Reset cyclical counters and switch back to navigate mode when
Chris@608 375 a new session is started
Chris@579 376
Chris@675 377
Chris@2345 378 Changes in Sonic Visualiser 2.1 (16 May 2013) since the previous release 2.0.1:
Chris@579 379
Chris@579 380 - Fix incorrect handling of FixedSampleRate outputs (Vamp SDK fix)
Chris@675 381
Chris@579 382 - Make it easier to see results from transforms that return a single point
Chris@675 383
Chris@579 384 - Make labelling clearer on time-value layers
Chris@675 385
Chris@579 386 - Add discrete-curve mode for time-value layers (for curves with gaps)
Chris@675 387
Chris@579 388 - Update code to build against Qt5
Chris@523 389
Chris@675 390
Chris@2345 391 Changes in Sonic Visualiser 2.0.1 ( Mar 2013) since the previous release 2.0:
Chris@523 392
Chris@523 393 - Fix incorrect samplerate in reading m4a files on OS/X
Chris@512 394
Chris@675 395
Chris@2345 396 Changes in Sonic Visualiser 2.0 (16 July 2012) since the previous release 1.9:
Chris@512 397
Chris@512 398 - Support 64-bit builds on OS/X (using CoreAudio instead of
Chris@512 399 obsolete QuickTime audio file reader)
Chris@512 400
Chris@512 401 - Simplify RDF reading and fix some bugs. Now requires Dataquay
Chris@512 402 (http://breakfastquay.com/dataquay/) rather than using Redland
Chris@512 403 directly. Release builds use Sord/Serd rather than Redland
Chris@512 404
Chris@512 405 - Add a fullscreen mode on the F11 key
Chris@471 406
Chris@675 407

Chris@394 417
Chris@675 418
Chris@2345 419 Changes in Sonic Visualiser 1.8 (08 Apr 2011) since the previous release 1.7.2:
Chris@394 420
Chris@394 421 - Sonic Visualiser now registers as a file type handler on OS/X,
Chris@394 422 providing better integration with the desktop generally (Dan Stowell)
Chris@394 423
Chris@394 424 - There is a new function to toggle all Time Rulers at once (key #)
Chris@394 425
Chris@407 426 - The CSV import dialog has been overhauled, allowing more flexible
Chris@407 427 selection of purpose for each column
Chris@407 428
Chris@394 429 - Text overlays are now easier to read on dark backgrounds
Chris@394 430
Chris@394 431 - Hidden layers are now ignored when exporting an image (Dan Stowell)
Chris@394 432
Chris@394 433 - A crash when starting a new session or exiting the application
Chris@394 434 after loading a session with saved alignment data has been fixed
Chris@394 435
Chris@394 436 - The duplication of right-button menu functions when multiple files
Chris@394 437 were loaded has been fixed
Chris@394 438
Chris@394 439 - The layer-add menu functions now have shortcuts (Dan Stowell)
Chris@394 440
Chris@394 441 - The codebase has been reorganised into libraries and a configure
Chris@394 442 step added. It should be easier to build and maintain on OS/X and
Chris@394 443 Linux than previously, although it won't make much difference on
Chris@394 444 Windows.
Chris@394 445
Chris@397 446 - A Czech translation is now included (thanks to Pavel Fric).
Chris@397 447
Chris@675 448
Chris@2345 449 Changes in Sonic Visualiser 1.7.2 (05 May 2010) since the previous release 1.7.1:
Chris@394 450
Chris@394 451 - The time-value layer now has an origin line and an option to
Chris@394 452 show derivatives (change from one point to the next) rather than
Chris@394 453 raw values
Chris@394 454
Chris@394 455 - A static initialiser race has been fixed, possibly fixing an
Chris@394 456 occasional crash on startup in Windows
Chris@394 457
Chris@394 458 - A crash when pressing Play straight after New Session has been
Chris@394 459 fixed
Chris@394 460
Chris@675 461
Chris@2345 462 Changes in Sonic Visualiser 1.7.1 (22 Oct 2009) since the previous release 1.7:
Chris@394 463
Chris@394 464 - The RDF importer does a better job of assigning labels to layers,
Chris@394 465 layers to panes, and values to labelled regions
Chris@394 466
Chris@394 467 - Interactive editing in the Text layer benefits from the same
Chris@394 468 improvements as made in 1.7 to Note and Region layers
Chris@394 469
Chris@394 470 - The layer data editor window has a text search feature
Chris@394 471
Chris@394 472 - The main window status bar now shows the last label to have passed
Chris@394 473 the playback position in the current layer, at the right end of the
Chris@394 474 status bar
Chris@394 475
Chris@394 476 - The Russian translation has been updated (thanks Alexandre)
Chris@394 477
Chris@675 478
Chris@2345 479 Changes in Sonic Visualiser 1.7 (05 Sep 2009) since the previous release 1.6:
Chris@394 480
Chris@394 481 - A new "Insert Item At Selection" function on the Edit menu
Chris@394 482 can be used to create Note and Region layer items whose time
Chris@394 483 extents correspond to the current selection(s)
Chris@394 484
Chris@394 485 - Interactively editing points in the Note and Region layers
Chris@394 486 now works much more smoothly
Chris@394 487
Chris@394 488 - SV can now import MIDI files that use SMPTE timecode for event
Chris@394 489 timing (importing MIDI files using with the more common
Chris@394 490 timebase-based timing was already supported)
Chris@394 491
Chris@394 492 - Time values throughout the display may optionally be shown in
Chris@394 493 seconds and frames at various frame rates
Chris@1520 494
Chris@394 495 - A crash on exit in Windows has been fixed
Chris@394 496
Chris@394 497 - A very unobtrusive user survey is now included
Chris@394 498
Chris@394 499 - Various other bug fixes.
Chris@394 500
Chris@675 501
Chris@2345 502 Changes in Sonic Visualiser 1.6 (22 Jun 2009) since the previous release 1.5:
Chris@394 503
Chris@394 504 - The Colour 3D Plot layer now supports logarithmic vertical
Chris@394 505 scale and linear interpolation options.
Chris@394 506
Chris@394 507 - A new colour scheme (High Gain) has been added for spectrogram
Chris@394 508 and Colour 3D Plot, which improves readability for some data.
Chris@394 509
Chris@394 510 - Further performance improvements have been made to Colour 3D
Chris@394 511 Plot.
Chris@394 512
Chris@394 513 - Various other bug fixes.
Chris@394 514
Chris@675 515
Chris@2345 516 Changes in Sonic Visualiser 1.5 (16 Mar 2009) since the previous release 1.4:
Chris@394 517
Chris@394 518 - You can now insert time instants, time values, and notes using
Chris@394 519 a MIDI device during playback. If a time value or note layer is
Chris@394 520 current it will be used for insertion (giving a value equal to
Chris@394 521 the pitch class, or the played note, respectively); otherwise an
Chris@394 522 existing or new time instants layer will be used just as it is
Chris@394 523 when inserting instants using the PC keyboard. Using a MIDI
Chris@394 524 device should give better timing than using the PC keyboard.
Chris@394 525
Chris@394 526 - There is a new Activity Log window with a (purely informative) list
Chris@394 527 of events and user interactions that happen while SV is running.
Chris@394 528
Chris@394 529 - The spectrogram has somewhat improved graphical scaling, and
Chris@394 530 this is now the default (being much faster than the 4x oversampled
Chris@394 531 method). The previous default is still available as a preference.
Chris@394 532
Chris@394 533 - Visualisation of very dense colour plots (such as spectrograms
Chris@394 534 calculated by plugins) is substantially faster in this release.
Chris@394 535
Chris@394 536 - Spectrogram display is now faster in many circumstances.
Chris@394 537
Chris@394 538 - Alignment using the MATCH plugin is faster on OS/X than before.
Chris@394 539
Chris@394 540 - SV will take into account RDF plugin descriptions, if available,
Chris@394 541 in order to make somewhat better decisions about display of plugin
Chris@394 542 outputs (for example, placing segmentation data into a layer with
Chris@394 543 segmentation plot type).
Chris@394 544
Chris@394 545 - You can now switch layers by clicking on the spare area at the left
Chris@394 546 end of the pane that is also used for the current pane indicator.
Chris@394 547
Chris@394 548 - The vertical black lines dividing segments in the time value
Chris@394 549 layer's segmentation plot style are now optional.
Chris@394 550
Chris@394 551 - Several widget layout bugs on OS/X have been fixed.
Chris@394 552
Chris@394 553 - Several serious crashing, deadlock, and data corruption bugs have
Chris@394 554 been fixed.
Chris@394 555
Chris@394 556
Chris@2345 557 Changes in Sonic Visualiser 1.4 (05 Dec 2008) since the previous release 1.3:
Chris@394 558
Chris@394 559 - SV now has a Region layer type, used for display of features with
Chris@394 560 durations. It also supports Vamp v2.0 plugins that provide durations
Chris@394 561 for features.
Chris@394 562
Chris@394 563 - Layer data can now be imported from RDF described using the Audio
Chris@394 564 Features Ontology, as well as from the existing text file types. SV
Chris@394 565 can also export annotation layer data to RDF/Turtle, although in a
Chris@394 566 somewhat simplistic manner at present.
Chris@394 567
Chris@394 568 - You can search for transforms by text in the new "Find a Transform"
Chris@394 569 dialog. This searches both installed plugins, and plugins that have
Chris@394 570 not been installed but that have descriptions available on the
Chris@394 571 semantic web.
Chris@394 572
Chris@394 573 - You can now zoom and scroll vertically in the time-value, note,
Chris@394 574 and colour 3d plot layers.
Chris@394 575
Chris@394 576 - Sonic Visualiser can now load sessions from uncompressed XML files
Chris@394 577 as well as its own compressed-XML .sv format. Files with extension
Chris@394 578 .xml that contain suitable session data will be loaded as sessions.
Chris@394 579 Note that .xml extension files still do not show up in the default
Chris@394 580 file load filter. This is intentional, as there may be any kind of
Chris@394 581 data in them -- if you want to load uncompressed session files from
Chris@394 582 XML, you need to know you're doing it.
Chris@394 583
Chris@394 584 - Several crashes and other bugs have been fixed.
Chris@394 585
Chris@675 586
Chris@2345 587 Changes in Sonic Visualiser 1.3 (10 Jul 2008) since the previous release 1.2:
Chris@394 588
Chris@394 589 - There is a new spreadsheet-style data viewer and editor for
Chris@394 590 viewing and editing the data in some types of annotation layer.
Chris@394 591
Chris@394 592 - Alignments are now saved to the session file.
Chris@394 593
Chris@394 594 - The spectrogram layer is usually somewhat faster than it was.
Chris@394 595
Chris@394 596 - You can now hold Shift while dragging to move an item, in order
Chris@394 597 to override the initial drag resistance introduced in 1.2.
Chris@394 598
Chris@394 599 - The gross mis-labelling of time lines in the ruler has been fixed.
Chris@394 600
Chris@394 601 - There is a new, somewhat provisional PulseAudio output driver.
Chris@394 602
Chris@394 603 - Several other bug fixes.
Chris@394 604
Chris@675 605
Chris@2345 606 Changes in Sonic Visualiser 1.2 (20 Feb 2008) since the previous release 1.0:
Chris@394 607
Chris@394 608 - SV now supports time-alignment of multiple performances of a work
Chris@394 609 loaded at the same time. This option is enabled when the MATCH Vamp
Chris@394 610 plugin is installed. When alignment is switched on and more than one
Chris@394 611 audio file is open, SV will assume that all open files are
Chris@394 612 differently timed performances of the same work, and will calculate
Chris@394 613 time alignments for them. Playback will then play only a single file
Chris@394 614 at a time, and the playback cursors in other files will track at the
Chris@394 615 varying speeds to try to ensure that each is at the same point in the
Chris@394 616 underlying score. This enables effective comparison of several such
Chris@394 617 files, as well as a meaningful way to switch from one performance to
Chris@394 618 another during playback (ensuring that the switch happens at the
Chris@394 619 correct point in the performance being switched to).
Chris@394 620
Chris@394 621 - There is a new Image layer, which can display images from the
Chris@394 622 local filesystem or retrieved via HTTP or FTP.
Chris@394 623
Chris@394 624 - A new measurement tool has been added. With the measurement tool
Chris@394 625 selected, dragging in a pane draws a rectangle labelled with the
Chris@394 626 scale values for its start and end corners and its size. You can
Chris@394 627 have any number of measurements present at once; they are associated
Chris@394 628 with the top layer, their scale values depend on the scale for that
Chris@394 629 layer, and they are only shown when that layer is at the top and the
Chris@394 630 measurement tool is active. Measurements are saved and reloaded in
Chris@394 631 the session file. Drawing measurements can be undone and redone, and
Chris@394 632 a measurement can be deleted by hitting Del when highlighted. Note
Chris@394 633 that the measurement tool shows the scale values associated with the
Chris@394 634 pixel positions of the mouse when dragging, not any values associated
Chris@394 635 with actual features present in the audio or its analysis (e.g. the
Chris@394 636 values are not rounded to the nearest spectrogram bin).
Chris@394 637
Chris@394 638 - You can double-click using the measurement tool in the spectrogram
Chris@394 639 to get an instant measurement rectangle for a feature. This is a
Chris@394 640 purely graphical feature that works by calculating the boundary of a
Chris@394 641 contiguous region of pixels "similar to" the one you double-clicked
Chris@394 642 on; it does not use audio analysis. Adjusting the gain and colour
Chris@394 643 scheme etc of the spectrogram will (by design) affect the
Chris@394 644 measurements obtained this way.
Chris@394 645
Chris@394 646 - The spectrum can now optionally show frequency estimates of peaks
Chris@394 647 aligned with a piano keyboard along the horizontal axis (this needs
Chris@394 648 some refinement).
Chris@394 649
Chris@394 650 - The harmonic cursor in the spectrogram has moved from the Select
Chris@394 651 tool to the Measurement tool. There is now a similar harmonic cursor
Chris@394 652 in the spectrum. Both of them show more information as text
Chris@394 653 alongside the cursor than previously.
Chris@394 654
Chris@394 655 - There is a new Erase tool for erasing individual points from an
Chris@394 656 editable layer.
Chris@394 657
Chris@394 658 - Several keyboard shortcuts have changed -- all of the Alt+key
Chris@394 659 shortcuts now either use Ctrl or a plain keypress with no modifier,
Chris@394 660 to avoid clashes with window manager shortcuts and to make them
Chris@394 661 easier to use and remember
Chris@394 662
Chris@394 663 - The playback controls are now in a Playback menu as well as the
Chris@394 664 toolbar.
Chris@394 665
Chris@394 666 - There is a new key and mouse control reference under Help (or press
Chris@394 667 F2).
Chris@394 668
Chris@394 669 - You can double-click on a pane in navigate mode to jump to a time.
Chris@394 670
Chris@394 671 - All of the single-colour layers (waveform, time values etc) now
Chris@394 672 allow you to define your own colours as well as using the built-in
Chris@394 673 set. The colour of a layer is now shown next to its name on the pane.
Chris@394 674
Chris@394 675 - When you add a new single-colour layer it will use a default colour
Chris@394 676 that is not yet in use in another layer (if there is one).
Chris@394 677
Chris@394 678 - Single-colour layers can now optionally have black backgrounds (with
Chris@394 679 a set of lighter colours in the default colour palette that use black
Chris@394 680 backgrounds by default).
Chris@394 681
Chris@394 682 - There's a new Printer colour scheme in the spectrogram with only a
Chris@394 683 small number of grey shades.
Chris@394 684
Chris@394 685 - Vertical zoom in a log-scaled spectrogram is much more intuitive;
Chris@394 686 it now leaves the point that was in the centre of the visible area in
Chris@394 687 the centre after zoom, instead of the point that was in the centre of
Chris@394 688 the linear range corresponding to the visible area.
Chris@394 689
Chris@394 690 - You can now turn a colour 3d plot layer upside down by clicking the
Chris@394 691 Invert Vertical Scale button.
Chris@394 692
Chris@394 693 - There's a new Layer Summary window which shows the panes and
Chris@394 694 layer data in a tree layout. This is very simplistic at the moment.
Chris@394 695
Chris@394 696 - Each pane now has an [X] button at its top left, which removes that
Chris@394 697 pane when clicked.
Chris@394 698
Chris@394 699 - There's a new Solo play mode toggle button; when active, only the
Chris@394 700 currently selected pane is played. This is also the default when
Chris@394 701 time alignment is in use.
Chris@394 702
Chris@394 703 - Rewind/ffwd now stay confined to the selection if Play Selection is
Chris@394 704 enabled; also, the rewind and ffwd "one step" buttons are now enabled
Chris@394 705 even if there is no time instants layer for them to align to (they
Chris@394 706 align to the time ruler instead and so jump in steps of a size
Chris@394 707 dependent on the zoom level).
Chris@394 708
Chris@394 709 - You can now export note layers to MIDI.
Chris@394 710
Chris@394 711 - MIDI note velocity is partially supported. Note velocity is
Chris@394 712 retained when importing and exporting MIDI and is used in playback,
Chris@394 713 but it is not yet shown in the display and cannot yet be edited.
Chris@394 714
Chris@394 715 - You can now drag-and-drop files (of whatever type) onto SV from
Chris@394 716 other programs such as file managers or web browsers.
Chris@394 717
Chris@394 718 - mp3 files (and Ogg, but they aren't supported on Windows at the
Chris@394 719 moment) are now decoded in a background thread so you can see the
Chris@394 720 start of the track without waiting for the rest to decode.
Chris@394 721
Chris@394 722 - Mac builds of SV can now load AAC/mp4 files and anything else
Chris@394 723 supported by QuickTime.
Chris@394 724
Chris@394 725 - There is now an option to resample audio files on import if they
Chris@394 726 don't match the samplerate of the first file loaded. By default this
Chris@394 727 is switched off, as it affects the visible waveform. The default
Chris@394 728 behaviour is unchanged (play at the wrong rate). There is still no
Chris@394 729 option to handle multiple rates "correctly" (i.e. by resampling
Chris@394 730 on playback and showing the waveforms at different resolutions
Chris@394 731 according to each one's underlying rate) and there probably never
Chris@394 732 will be.
Chris@394 733
Chris@394 734 - SV can now open .m3u playlist files, though it's a hazardous thing
Chris@394 735 to do as it simply loads all the files in the playlist at once.
Chris@394 736
Chris@394 737 - SV now has various options for how to number tapped time instants
Chris@394 738 (bar/beat, plain counter, time in seconds, tempo etc).
Chris@394 739
Chris@394 740 - The official builds use Qt 4.3, which fixes some nasty
Chris@394 741 bugs in the file dialog that the version 1.0 builds suffered from.
Chris@394 742
Chris@2345 743
Chris@2345 744 Changes in Sonic Visualiser 1.0 (10 May 2007):
Chris@2345 745
Chris@2345 746 - First official release of Sonic Visualiser
Chris@2345 747
