Chris@2211 1
Chris@2328 2 Changes in Sonic Visualiser v4.0 since the previous release 3.3:
Chris@2328 3
Chris@2328 4 - Add Time-Frequency Box annotation layer type. Because this
Chris@2328 5 introduces a new layer type into the session file format, the major
Chris@2328 6 version number has been bumped to v4.0. (Sessions saved from v4.0
Chris@2328 7 can be opened in earlier versions of Sonic Visualiser, but any
Chris@2328 8 Time-Frequency Box layers will not be loaded.)
Chris@2328 9
Chris@2328 10
Chris@2328 11 Changes in Sonic Visualiser v3.3 (May 2019) since the previous release 3.2.1:
Chris@2211 12
Chris@2211 13 - Add support for reading the Opus audio codec on all platforms
Chris@2211 14
Chris@2211 15 - Add support for WMA and AAC formats on 64-bit Windows. (AAC was
Chris@2211 16 already supported on macOS.) Note that AAC support on Windows does
Chris@2211 17 not support "gapless" import, i.e. removing the encoder gaps at
Chris@2211 18 start and end of the stream
Chris@2211 19
Chris@2260 20 - Add ability to choose the field separator when importing CSV and
Chris@2260 21 CSV-like files, if more than one possible candidate separator is
Chris@2260 22 found in the file
Chris@2260 23
Chris@2260 24 - Fix crash when closing session or starting a new session while
Chris@2260 25 calculating alignment of multiple audio files
Chris@2260 26
Chris@2260 27 - Fix crash when running certain plugins that call for
Chris@2260 28 frequency-domain input at non-power-of-two block sizes
Chris@2260 29
Chris@2260 30 - Fix wandering left edge of measure-tool rectangle while dragging
Chris@2260 31 out the area
Chris@2260 32
Chris@2260 33 - Ensure that plugin stderr debug output is logged to the SV log file
Chris@2260 34
Chris@2002 35
Chris@2175 36 Changes in Sonic Visualiser 3.2.1 (Jan 2019) since the previous release 3.2:
Chris@2175 37
Chris@2175 38 - Fix failure to record from built-in microphone on macOS 10.14
Chris@2175 39 (caused by lack of microphone permission request text)
Chris@2175 40
Chris@2175 41 - Fix crash when closing SV or starting a new session during recording
Chris@2175 42
Chris@2175 43 - Fix crash on exit in some builds that disable OSC support
Chris@2175 44
Chris@2175 45 - Fix flashing effect when scrolling certain configurations of colour 3d
Chris@2175 46 plot layer leftwards
Chris@2175 47
Chris@2175 48
Chris@2175 49 Changes in Sonic Visualiser 3.2 (Dec 2018) since the previous release 3.1.1:
Chris@2002 50
Chris@2048 51 - Add ability to zoom closer than one sample per pixel, so as to see
Chris@2048 52 the interpolated signal level between samples
Chris@2048 53
Chris@2110 54 - Add oversampling control to the spectrogram and spectrum layers
Chris@2110 55
Chris@2110 56 - Highlight and label frequency peaks in the spectrum as the mouse
Chris@2110 57 rolls over them, when enabled in the parameter area
Chris@2110 58
Chris@2002 59 - Add feature to convert and import audio from a CSV data file
Chris@2002 60
Chris@2048 61 - Add some new colour maps, and restore the old Blue on Black one
Chris@2048 62
Chris@2110 63 - Speed up spectrum rendering at high resolutions
Chris@2110 64
Chris@2048 65 - Fix failure to pass Nyquist bins correctly to
Chris@2048 66 frequency-domain-input Vamp plugins in some circumstances
Chris@2048 67
Chris@2110 68 - Fix sometimes incorrect shortcut associations for new-layer menu
Chris@2110 69 items
Chris@2110 70
Chris@2139 71 - Various other rendering improvements and bug fixes
Chris@2110 72
cannam@1948 73
cannam@1948 74 Changes in Sonic Visualiser 3.1.1 (Aug 2018) since the previous release 3.1:
cannam@1948 75
cannam@1948 76 - Fix failure to record correctly into an empty session with certain
cannam@1948 77 audio drivers
cannam@1948 78
Chris@1958 79 - Fix failure to run LADSPA plugins at all, except with some unusual
Chris@1958 80 path layouts
Chris@1958 81
Chris@1958 82 - Fix failure to silence sonified notes when rewinding backwards or
Chris@1958 83 jumping back from a loop endpoint
Chris@1958 84
cannam@1948 85 - Fix macOS .dmg image so as to use older HFS+ filesystem for compatibility
cannam@1948 86
Chris@1871 87
Chris@1932 88 Changes in Sonic Visualiser 3.1 (July 2018) since the previous release 3.0.3:
Chris@1871 89
Chris@1871 90 - Add Plugins tab to Preferences dialog, from which you can review
Chris@1871 91 the plugin load paths and see which plugins were loaded from which
Chris@1871 92 locations, and also customise load paths (though the various path
Chris@1871 93 environment variables are still supported)
Chris@1871 94
Chris@1935 95 - Stream the export of audio data and other CSV data so that
Chris@1935 96 very large exports don't hang the UI or run us out of memory
Chris@1935 97 (thanks to Lucas Thompson)
Chris@1935 98
Chris@1935 99 - Ensure vertical scale appears for auto-align layers when there is
Chris@1935 100 nothing else to auto-align them to
Chris@1935 101
Chris@1871 102 - Fix another long-standing Windows-platform wide-char/utf8
Chris@1871 103 conversion problem, with environment variable naming and contents
Chris@1871 104
Chris@1871 105 - Improve handling of incomplete session loads, i.e. situations where
Chris@1871 106 the audio files referred to by a session could not be found -
Chris@1871 107 previously the session could be re-saved immediately thus losing
Chris@1871 108 the audio reference; now at least we disable Save (enabling only
Chris@1871 109 Save As) and show a warning
Chris@1871 110
Chris@1871 111 - Update pane and layer menu shortcuts so that the
Chris@1871 112 waveform/spectrogram/etc shortcuts (Shift+G etc) operate on the
Chris@1871 113 source model in the currently-selected pane rather than the main
Chris@1871 114 model. This is a backward-incompatible change but is a far more
Chris@1871 115 intuitive way for the function to work
Chris@1871 116
Chris@1935 117 - Use dark background for bright colours in time-value/note/etc
Chris@1935 118 layers as well as e.g. waveforms - this is how it was always
Chris@1935 119 "intended to" work, but it is a backward-incompatible change
Chris@1935 120
Chris@1871 121 - Make "Select All" select the whole span of everything that exists,
Chris@1871 122 not just the main model
Chris@1871 123
Chris@1871 124 - Add horizontal scale to Spectrum layer
Chris@1871 125
Chris@1871 126 - Improve spacing and labelling of vertical log scales
Chris@1871 127
Chris@1871 128 - Update build system for better Cap'n Proto version support and to
Chris@1871 129 use Repoint for code management in the repository
Chris@1871 130
Chris@1871 131 - Various other bug fixes
Chris@1871 132
Chris@1702 133
Chris@1702 134 Changes in Sonic Visualiser 3.0.3 (May 2017) since the previous release 3.0.2:
Chris@1702 135
Chris@1702 136 - Improve decisions about where and how to label vertical scales
Chris@1702 137
Chris@1702 138 - Update build support material and documentation to reflect the
Chris@1702 139 official release of Cap'n Proto 0.6 (which we can now use rather
Chris@1702 140 than depending on git builds)
Chris@1702 141
Chris@1669 142
Chris@1669 143 Changes in Sonic Visualiser 3.0.2 (Mar 2017) since the previous release 3.0.1:
Chris@1669 144
Chris@1669 145 - Fix crash when changing parameters for spectrum view
Chris@1669 146
Chris@1669 147 - Fix incorrect measure tool crosshairs in spectrum view
Chris@1669 148
Chris@1669 149 - Update Russian and Czech UI translations (thanks to Alexandre Prokoudine
Chris@1669 150 and Pavel Fric respectively)
Chris@1702 151
Chris@1658 152
Chris@1658 153 Changes in Sonic Visualiser 3.0.1 (Mar 2017) since the previous release 3.0:
Chris@1658 154
Chris@1658 155 - Fix crashes with MIDI devices and speedup/slowdown control on Windows
Chris@1661 156
Chris@1658 157 - Update MIDI input driver layer
Chris@1447 158
Chris@1661 159
Chris@1624 160 Changes in Sonic Visualiser 3.0 (Mar 2017) since the previous release 2.5:
Chris@1447 161
Chris@1516 162 - Add ability to record audio, and ability to change the audio device
Chris@1516 163 for playback or recording in the preferences
Chris@1447 164
Chris@1447 165 - Add complete support for high-resolution (Hi-DPI or retina)
Chris@1511 166 displays, including for layer data rendering as well as UI controls
Chris@1511 167 and icons. This makes the biggest difference when using a retina
Chris@1511 168 Mac, on which previous versions did not render layer data at retina
Chris@1447 169 resolution, but it also improves scaling and rendering of UI
Chris@1447 170 elements on Hi-DPI displays on Windows and Linux
Chris@1447 171
Chris@1451 172 - Add ability to export scalable (SVG) image files
Chris@1451 173
Chris@1447 174 - Run plugins in a separate process, so that if a plugin crashes, it
Chris@1447 175 no longer brings down Sonic Visualiser with it. In every other
Chris@1447 176 respect the behaviour should be unchanged
Chris@1447 177
Chris@1447 178 - Scan plugins on startup in a separate process, and report on any
Chris@1447 179 that crash or won't load
Chris@1447 180
Chris@1527 181 - Add ability to open, display, and analyse very long audio files (of
Chris@1527 182 more than 2^32 sample frames)
Chris@1527 183
Chris@1447 184 - Change mp3 file loading so as to compensate for encoder/decoder
Chris@1447 185 delay and padding (using "gapless playback" logic). While this is a
Chris@1447 186 real improvement, unfortunately it does mean that the initial
Chris@1447 187 padding in mp3 file load has changed from previous versions, which
Chris@1447 188 may mean some sessions saved in previous versions are no longer
Chris@1447 189 correctly aligned. It's not a great idea to use mp3 as a file
Chris@1447 190 format of record, because of differences like this between
Chris@1447 191 decoders. The previous behaviour is still available as a preference.
Chris@1447 192
Chris@1470 193 - Add new Hybrid normalisation type for spectrogram and colour 3d
Chris@1470 194 plot layers. This normalises each column to its peak value and then
Chris@1470 195 scales the normalised values by the log of the peak in order to
Chris@1470 196 restore some distinction in scale between columns with different
Chris@1470 197 levels. It can provide quite visually clear results.
Chris@1470 198
Chris@1447 199 - Add function to subdivide time instant layers into regular
Chris@1447 200 intervals (and its inverse)
Chris@1447 201
Chris@1447 202 - Add new preference for default colour scales
Chris@1447 203
Chris@1578 204 - Add a basic ability to zoom (in the frequency axis) to the spectrum
Chris@1624 205
Chris@1447 206 - Switch to using combined level/pan controls in layer property boxes
Chris@1447 207 and for the main volume control
Chris@1447 208
Chris@1520 209 - Make CSV file reader better able to handle files with varying
Chris@1520 210 numbers of columns
Chris@1520 211
Chris@1516 212 - Fix a number of problems on Windows with loading and saving some
Chris@1516 213 file formats to filenames not representable in system codepage
Chris@1516 214
Chris@1520 215 - Add "What's New" dialog
Chris@1520 216
Chris@1527 217 - Finally switch the Windows build to 64-bit by default (with
Chris@1447 218 adapters to run either 32- or 64-bit plugins)
Chris@1451 219
Chris@1447 220
Chris@1520 221 Changes in Sonic Visualiser 2.5 (Oct 2015) since the previous release 2.4.1:
Chris@1072 222
Chris@1072 223 - Add unit-converter dialog, for converting between various pitch and
Chris@1072 224 timing units
Chris@1072 225
Chris@1072 226 - Fix failure to reload note layers from session file
Chris@1072 227
Chris@1072 228 - Use a more sensible scale for the play-speed dial
Chris@1072 229
Chris@1072 230 - Fix crash when importing very wide CSV files
Chris@1072 231
Chris@1072 232 - Fix generation of wrong layer type from some CSV files
Chris@1072 233
Chris@1072 234 - Fix failure to export last instant in a time-instant layer
Chris@1072 235
Chris@1457 236
Chris@1520 237 Changes in Sonic Visualiser 2.4.1 (Oct 2014) since the previous release 2.4:
Chris@876 238
Chris@876 239 - Fix a crash when rendering certain colour 3d plot layers
Chris@716 240
Chris@1457 241
Chris@1520 242 Changes in Sonic Visualiser 2.4 (Sep 2014) since the previous release 2.3:
Chris@714 243
Chris@776 244 - Add support for left/right scrolling using a two-finger touchpad
Chris@776 245 gesture (where available)
Chris@776 246
Chris@716 247 - Make the octave numbering into a configurable option, and change
Chris@716 248 the default. Previously Sonic Visualiser labelled middle-C as "C3";
Chris@716 249 now it labels middle-C as "C4", a more common standard in the world
Chris@776 250 outside MIDI sequencer software. The previous system is available
Chris@776 251 as an option in the Preferences. This affects only the visible
Chris@776 252 labels: there is no change to analysis or to the file format
Chris@714 253
Chris@714 254 - Sonify time-value layers. Any time-value curve whose scale unit is
Chris@714 255 set to Hz will now acquire a playback toggle control; this control
Chris@714 256 is off by default, but if it is switched on, the curve will be
Chris@714 257 played back using a variable-frequency sound generator
Chris@714 258
Chris@714 259 - Add support for playback of note layers with non-MIDI frequencies
Chris@714 260 (formerly the note playback was limited to exact MIDI pitch)
Chris@714 261
Chris@714 262 - Change the default playback sample for note layers from piano to an
Chris@714 263 electric piano with sustain. The piano sample is still available,
Chris@714 264 and any sessions saved using it should continue to use it
Chris@714 265
Chris@867 266 - Add a cancel button for Vamp plugin processing: currently,
Chris@867 267 cancelling a transform results in a part-complete layer rather than
Chris@867 268 removing the results
Chris@867 269
Chris@790 270 - Add keyboard shortcuts to cycle the current layer (in addition to
Chris@790 271 the existing ones to cycle the current pane)
Chris@790 272
Chris@790 273 - Fix various bugs related to layer ordering: layer tabs re-ordering
Chris@790 274 themselves randomly when new layer added, layers being ordered
Chris@791 275 randomly when saving and reloading a session
Chris@790 276
Chris@848 277 - Fix incorrect interaction with non-Unicode usernames when creating
Chris@848 278 temporary and template directories on Windows
Chris@848 279
Chris@714 280 - Shade the start and end of the main audio file, to make them easier
Chris@714 281 to see for files that start or end in silence
Chris@714 282
Chris@714 283 - Speed up rendering and scrolling in time-value layers
Chris@714 284
Chris@714 285 - Make it possible to import CSV files directly into Note layers by
Chris@714 286 adding Pitch as a data type in the CSV file import dialog
Chris@675 287
Chris@856 288 - Fix play pointer jump to wrong frame when clicking on row in the
Chris@856 289 layer edit dialog
Chris@856 290
Chris@848 291 - Fix problems with keyboard shortcuts when using Qt5 on OS/X. This
Chris@848 292 is the first release in which the official builds use Qt5 for all
Chris@848 293 platforms.
Chris@848 294
Chris@675 295
Chris@1520 296 Changes in Sonic Visualiser 2.3 (Dec 2013) since the previous release 2.2:
Chris@675 297
Chris@675 298 - Add a startup welcome dialog that also explains what SV makes
Chris@675 299 network connections for and allows user to forbid them
Chris@675 300
Chris@675 301 - Add "Export Audio Data" feature
Chris@675 302
Chris@675 303 - Show piano keyboard scale in note and time-value layers as well
Chris@675 304 as spectrogram, where vertical scale is log Hz; also show
Chris@675 305 numerical scale in note and region layers when not auto-aligned
Chris@675 306
Chris@675 307 - Speed up CSV file import and avoid showing crazily wide window
Chris@675 308 for CSV file format dialog when file has lots of columns
Chris@675 309
Chris@675 310 - Fix incorrectly saved window geometry when exiting from maximised
Chris@675 311 state
Chris@675 312
Chris@675 313 - Reduce number of timer wakeups when idle
Chris@675 314
Chris@675 315 - Add American English translation and make choice of translation
Chris@675 316 into a preference (defaulting to system locale)
Chris@675 317
Chris@675 318 - Permit installation to non-default location with Windows installer
Chris@675 319 build
Chris@714 320
Chris@608 321
Chris@1520 322 Changes in Sonic Visualiser 2.2 (July 2013) since the previous release 2.1:
Chris@608 323
Chris@608 324 - Build with support for hidpi ("retina") text on OS/X
Chris@675 325
Chris@608 326 - Fix very slow analysis when using Ogg or FLAC files decoded
Chris@608 327 via libsndfile
Chris@675 328
Chris@608 329 - Fix inaccurate scale auto-align between time-value layers and
Chris@608 330 others
Chris@675 331
Chris@608 332 - Fix failure to open files specified on command line (or via
Chris@608 333 Open With) on Windows
Chris@675 334
Chris@608 335 - Reset cyclical counters and switch back to navigate mode when
Chris@608 336 a new session is started
Chris@579 337
Chris@675 338
Chris@1520 339 Changes in Sonic Visualiser 2.1 (May 2013) since the previous release 2.0.1:
Chris@579 340
Chris@579 341 - Fix incorrect handling of FixedSampleRate outputs (Vamp SDK fix)
Chris@675 342
Chris@579 343 - Make it easier to see results from transforms that return a single point
Chris@675 344
Chris@579 345 - Make labelling clearer on time-value layers
Chris@675 346
Chris@579 347 - Add discrete-curve mode for time-value layers (for curves with gaps)
Chris@675 348
Chris@579 349 - Update code to build against Qt5
Chris@523 350
Chris@675 351
Chris@523 352 Changes in Sonic Visualiser 2.0.1 since the previous release 2.0:
Chris@523 353
Chris@523 354 - Fix incorrect samplerate in reading m4a files on OS/X
Chris@512 355
Chris@675 356
Chris@1520 357 Changes in Sonic Visualiser 2.0 (July 2012) since the previous release 1.9:
Chris@512 358
Chris@512 359 - Support 64-bit builds on OS/X (using CoreAudio instead of
Chris@512 360 obsolete QuickTime audio file reader)
Chris@512 361
Chris@512 362 - Simplify RDF reading and fix some bugs. Now requires Dataquay
Chris@512 363 (http://breakfastquay.com/dataquay/) rather than using Redland
Chris@512 364 directly. Release builds use Sord/Serd rather than Redland
Chris@512 365
Chris@512 366 - Add a fullscreen mode on the F11 key
Chris@471 367
Chris@675 368
Chris@1520 369 Changes in Sonic Visualiser 1.9 (Oct 2011) since the previous release 1.8:
Chris@471 370
Chris@471 371 - Add session templates; save session as template; apply template to
Chris@471 372 session
Chris@471 373
Chris@471 374 - Tidy up the file open logic so as to remove the dialog asking how
Chris@471 375 to open a file, where possible
Chris@471 376
Chris@471 377 - Various bug fixes.
Chris@394 378
Chris@675 379
Chris@1520 380 Changes in Sonic Visualiser 1.8 (Apr 2011) since the previous release 1.7.2:
Chris@394 381
Chris@394 382 - Sonic Visualiser now registers as a file type handler on OS/X,
Chris@394 383 providing better integration with the desktop generally (Dan Stowell)
Chris@394 384
Chris@394 385 - There is a new function to toggle all Time Rulers at once (key #)
Chris@394 386
Chris@407 387 - The CSV import dialog has been overhauled, allowing more flexible
Chris@407 388 selection of purpose for each column
Chris@407 389
Chris@394 390 - Text overlays are now easier to read on dark backgrounds
Chris@394 391
Chris@394 392 - Hidden layers are now ignored when exporting an image (Dan Stowell)
Chris@394 393
Chris@394 394 - A crash when starting a new session or exiting the application
Chris@394 395 after loading a session with saved alignment data has been fixed
Chris@394 396
Chris@394 397 - The duplication of right-button menu functions when multiple files
Chris@394 398 were loaded has been fixed
Chris@394 399
Chris@394 400 - The layer-add menu functions now have shortcuts (Dan Stowell)
Chris@394 401
Chris@394 402 - The codebase has been reorganised into libraries and a configure
Chris@394 403 step added. It should be easier to build and maintain on OS/X and
Chris@394 404 Linux than previously, although it won't make much difference on
Chris@394 405 Windows.
Chris@394 406
Chris@397 407 - A Czech translation is now included (thanks to Pavel Fric).
Chris@397 408
Chris@675 409
Chris@1520 410 Changes in Sonic Visualiser 1.7.2 (May 2010) since the previous release 1.7.1:
Chris@394 411
Chris@394 412 - The time-value layer now has an origin line and an option to
Chris@394 413 show derivatives (change from one point to the next) rather than
Chris@394 414 raw values
Chris@394 415
Chris@394 416 - A static initialiser race has been fixed, possibly fixing an
Chris@394 417 occasional crash on startup in Windows
Chris@394 418
Chris@394 419 - A crash when pressing Play straight after New Session has been
Chris@394 420 fixed
Chris@394 421
Chris@675 422
Chris@1520 423 Changes in Sonic Visualiser 1.7.1 (Oct 2009) since the previous release 1.7:
Chris@394 424
Chris@394 425 - The RDF importer does a better job of assigning labels to layers,
Chris@394 426 layers to panes, and values to labelled regions
Chris@394 427
Chris@394 428 - Interactive editing in the Text layer benefits from the same
Chris@394 429 improvements as made in 1.7 to Note and Region layers
Chris@394 430
Chris@394 431 - The layer data editor window has a text search feature
Chris@394 432
Chris@394 433 - The main window status bar now shows the last label to have passed
Chris@394 434 the playback position in the current layer, at the right end of the
Chris@394 435 status bar
Chris@394 436
Chris@394 437 - The Russian translation has been updated (thanks Alexandre)
Chris@394 438
Chris@675 439
Chris@1520 440 Changes in Sonic Visualiser 1.7 (Sep 2009) since the previous release 1.6:
Chris@394 441
Chris@394 442 - A new "Insert Item At Selection" function on the Edit menu
Chris@394 443 can be used to create Note and Region layer items whose time
Chris@394 444 extents correspond to the current selection(s)
Chris@394 445
Chris@394 446 - Interactively editing points in the Note and Region layers
Chris@394 447 now works much more smoothly
Chris@394 448
Chris@394 449 - SV can now import MIDI files that use SMPTE timecode for event
Chris@394 450 timing (importing MIDI files using with the more common
Chris@394 451 timebase-based timing was already supported)
Chris@394 452
Chris@394 453 - Time values throughout the display may optionally be shown in
Chris@394 454 seconds and frames at various frame rates
Chris@1520 455
Chris@394 456 - A crash on exit in Windows has been fixed
Chris@394 457
Chris@394 458 - A very unobtrusive user survey is now included
Chris@394 459
Chris@394 460 - Various other bug fixes.
Chris@394 461
Chris@675 462
Chris@1520 463 Changes in Sonic Visualiser 1.6 (Jun 2009) since the previous release 1.5:
Chris@394 464
Chris@394 465 - The Colour 3D Plot layer now supports logarithmic vertical
Chris@394 466 scale and linear interpolation options.
Chris@394 467
Chris@394 468 - A new colour scheme (High Gain) has been added for spectrogram
Chris@394 469 and Colour 3D Plot, which improves readability for some data.
Chris@394 470
Chris@394 471 - Further performance improvements have been made to Colour 3D
Chris@394 472 Plot.
Chris@394 473
Chris@394 474 - Various other bug fixes.
Chris@394 475
Chris@675 476
Chris@1520 477 Changes in Sonic Visualiser 1.5 (Mar 2009) since the previous release 1.4:
Chris@394 478
Chris@394 479 - You can now insert time instants, time values, and notes using
Chris@394 480 a MIDI device during playback. If a time value or note layer is
Chris@394 481 current it will be used for insertion (giving a value equal to
Chris@394 482 the pitch class, or the played note, respectively); otherwise an
Chris@394 483 existing or new time instants layer will be used just as it is
Chris@394 484 when inserting instants using the PC keyboard. Using a MIDI
Chris@394 485 device should give better timing than using the PC keyboard.
Chris@394 486
Chris@394 487 - There is a new Activity Log window with a (purely informative) list
Chris@394 488 of events and user interactions that happen while SV is running.
Chris@394 489
Chris@394 490 - The spectrogram has somewhat improved graphical scaling, and
Chris@394 491 this is now the default (being much faster than the 4x oversampled
Chris@394 492 method). The previous default is still available as a preference.
Chris@394 493
Chris@394 494 - Visualisation of very dense colour plots (such as spectrograms
Chris@394 495 calculated by plugins) is substantially faster in this release.
Chris@394 496
Chris@394 497 - Spectrogram display is now faster in many circumstances.
Chris@394 498
Chris@394 499 - Alignment using the MATCH plugin is faster on OS/X than before.
Chris@394 500
Chris@394 501 - SV will take into account RDF plugin descriptions, if available,
Chris@394 502 in order to make somewhat better decisions about display of plugin
Chris@394 503 outputs (for example, placing segmentation data into a layer with
Chris@394 504 segmentation plot type).
Chris@394 505
Chris@394 506 - You can now switch layers by clicking on the spare area at the left
Chris@394 507 end of the pane that is also used for the current pane indicator.
Chris@394 508
Chris@394 509 - The vertical black lines dividing segments in the time value
Chris@394 510 layer's segmentation plot style are now optional.
Chris@394 511
Chris@394 512 - Several widget layout bugs on OS/X have been fixed.
Chris@394 513
Chris@394 514 - Several serious crashing, deadlock, and data corruption bugs have
Chris@394 515 been fixed.
Chris@394 516
Chris@394 517
Chris@1520 518 Changes in Sonic Visualiser 1.4 (Dec 2008) since the previous release 1.3:
Chris@394 519
Chris@394 520 - SV now has a Region layer type, used for display of features with
Chris@394 521 durations. It also supports Vamp v2.0 plugins that provide durations
Chris@394 522 for features.
Chris@394 523
Chris@394 524 - Layer data can now be imported from RDF described using the Audio
Chris@394 525 Features Ontology, as well as from the existing text file types. SV
Chris@394 526 can also export annotation layer data to RDF/Turtle, although in a
Chris@394 527 somewhat simplistic manner at present.
Chris@394 528
Chris@394 529 - You can search for transforms by text in the new "Find a Transform"
Chris@394 530 dialog. This searches both installed plugins, and plugins that have
Chris@394 531 not been installed but that have descriptions available on the
Chris@394 532 semantic web.
Chris@394 533
Chris@394 534 - You can now zoom and scroll vertically in the time-value, note,
Chris@394 535 and colour 3d plot layers.
Chris@394 536
Chris@394 537 - Sonic Visualiser can now load sessions from uncompressed XML files
Chris@394 538 as well as its own compressed-XML .sv format. Files with extension
Chris@394 539 .xml that contain suitable session data will be loaded as sessions.
Chris@394 540 Note that .xml extension files still do not show up in the default
Chris@394 541 file load filter. This is intentional, as there may be any kind of
Chris@394 542 data in them -- if you want to load uncompressed session files from
Chris@394 543 XML, you need to know you're doing it.
Chris@394 544
Chris@394 545 - Several crashes and other bugs have been fixed.
Chris@394 546
Chris@675 547
Chris@1520 548 Changes in Sonic Visualiser 1.3 (Jul 2008) since the previous release 1.2:
Chris@394 549
Chris@394 550 - There is a new spreadsheet-style data viewer and editor for
Chris@394 551 viewing and editing the data in some types of annotation layer.
Chris@394 552
Chris@394 553 - Alignments are now saved to the session file.
Chris@394 554
Chris@394 555 - The spectrogram layer is usually somewhat faster than it was.
Chris@394 556
Chris@394 557 - You can now hold Shift while dragging to move an item, in order
Chris@394 558 to override the initial drag resistance introduced in 1.2.
Chris@394 559
Chris@394 560 - The gross mis-labelling of time lines in the ruler has been fixed.
Chris@394 561
Chris@394 562 - There is a new, somewhat provisional PulseAudio output driver.
Chris@394 563
Chris@394 564 - Several other bug fixes.
Chris@394 565
Chris@675 566
Chris@1520 567 Changes in Sonic Visualiser 1.2 (Feb 2008) since the previous release 1.0:
Chris@394 568
Chris@394 569 - SV now supports time-alignment of multiple performances of a work
Chris@394 570 loaded at the same time. This option is enabled when the MATCH Vamp
Chris@394 571 plugin is installed. When alignment is switched on and more than one
Chris@394 572 audio file is open, SV will assume that all open files are
Chris@394 573 differently timed performances of the same work, and will calculate
Chris@394 574 time alignments for them. Playback will then play only a single file
Chris@394 575 at a time, and the playback cursors in other files will track at the
Chris@394 576 varying speeds to try to ensure that each is at the same point in the
Chris@394 577 underlying score. This enables effective comparison of several such
Chris@394 578 files, as well as a meaningful way to switch from one performance to
Chris@394 579 another during playback (ensuring that the switch happens at the
Chris@394 580 correct point in the performance being switched to).
Chris@394 581
Chris@394 582 - There is a new Image layer, which can display images from the
Chris@394 583 local filesystem or retrieved via HTTP or FTP.
Chris@394 584
Chris@394 585 - A new measurement tool has been added. With the measurement tool
Chris@394 586 selected, dragging in a pane draws a rectangle labelled with the
Chris@394 587 scale values for its start and end corners and its size. You can
Chris@394 588 have any number of measurements present at once; they are associated
Chris@394 589 with the top layer, their scale values depend on the scale for that
Chris@394 590 layer, and they are only shown when that layer is at the top and the
Chris@394 591 measurement tool is active. Measurements are saved and reloaded in
Chris@394 592 the session file. Drawing measurements can be undone and redone, and
Chris@394 593 a measurement can be deleted by hitting Del when highlighted. Note
Chris@394 594 that the measurement tool shows the scale values associated with the
Chris@394 595 pixel positions of the mouse when dragging, not any values associated
Chris@394 596 with actual features present in the audio or its analysis (e.g. the
Chris@394 597 values are not rounded to the nearest spectrogram bin).
Chris@394 598
Chris@394 599 - You can double-click using the measurement tool in the spectrogram
Chris@394 600 to get an instant measurement rectangle for a feature. This is a
Chris@394 601 purely graphical feature that works by calculating the boundary of a
Chris@394 602 contiguous region of pixels "similar to" the one you double-clicked
Chris@394 603 on; it does not use audio analysis. Adjusting the gain and colour
Chris@394 604 scheme etc of the spectrogram will (by design) affect the
Chris@394 605 measurements obtained this way.
Chris@394 606
Chris@394 607 - The spectrum can now optionally show frequency estimates of peaks
Chris@394 608 aligned with a piano keyboard along the horizontal axis (this needs
Chris@394 609 some refinement).
Chris@394 610
Chris@394 611 - The harmonic cursor in the spectrogram has moved from the Select
Chris@394 612 tool to the Measurement tool. There is now a similar harmonic cursor
Chris@394 613 in the spectrum. Both of them show more information as text
Chris@394 614 alongside the cursor than previously.
Chris@394 615
Chris@394 616 - There is a new Erase tool for erasing individual points from an
Chris@394 617 editable layer.
Chris@394 618
Chris@394 619 - Several keyboard shortcuts have changed -- all of the Alt+key
Chris@394 620 shortcuts now either use Ctrl or a plain keypress with no modifier,
Chris@394 621 to avoid clashes with window manager shortcuts and to make them
Chris@394 622 easier to use and remember
Chris@394 623
Chris@394 624 - The playback controls are now in a Playback menu as well as the
Chris@394 625 toolbar.
Chris@394 626
Chris@394 627 - There is a new key and mouse control reference under Help (or press
Chris@394 628 F2).
Chris@394 629
Chris@394 630 - You can double-click on a pane in navigate mode to jump to a time.
Chris@394 631
Chris@394 632 - All of the single-colour layers (waveform, time values etc) now
Chris@394 633 allow you to define your own colours as well as using the built-in
Chris@394 634 set. The colour of a layer is now shown next to its name on the pane.
Chris@394 635
Chris@394 636 - When you add a new single-colour layer it will use a default colour
Chris@394 637 that is not yet in use in another layer (if there is one).
Chris@394 638
Chris@394 639 - Single-colour layers can now optionally have black backgrounds (with
Chris@394 640 a set of lighter colours in the default colour palette that use black
Chris@394 641 backgrounds by default).
Chris@394 642
Chris@394 643 - There's a new Printer colour scheme in the spectrogram with only a
Chris@394 644 small number of grey shades.
Chris@394 645
Chris@394 646 - Vertical zoom in a log-scaled spectrogram is much more intuitive;
Chris@394 647 it now leaves the point that was in the centre of the visible area in
Chris@394 648 the centre after zoom, instead of the point that was in the centre of
Chris@394 649 the linear range corresponding to the visible area.
Chris@394 650
Chris@394 651 - You can now turn a colour 3d plot layer upside down by clicking the
Chris@394 652 Invert Vertical Scale button.
Chris@394 653
Chris@394 654 - There's a new Layer Summary window which shows the panes and
Chris@394 655 layer data in a tree layout. This is very simplistic at the moment.
Chris@394 656
Chris@394 657 - Each pane now has an [X] button at its top left, which removes that
Chris@394 658 pane when clicked.
Chris@394 659
Chris@394 660 - There's a new Solo play mode toggle button; when active, only the
Chris@394 661 currently selected pane is played. This is also the default when
Chris@394 662 time alignment is in use.
Chris@394 663
Chris@394 664 - Rewind/ffwd now stay confined to the selection if Play Selection is
Chris@394 665 enabled; also, the rewind and ffwd "one step" buttons are now enabled
Chris@394 666 even if there is no time instants layer for them to align to (they
Chris@394 667 align to the time ruler instead and so jump in steps of a size
Chris@394 668 dependent on the zoom level).
Chris@394 669
Chris@394 670 - You can now export note layers to MIDI.
Chris@394 671
Chris@394 672 - MIDI note velocity is partially supported. Note velocity is
Chris@394 673 retained when importing and exporting MIDI and is used in playback,
Chris@394 674 but it is not yet shown in the display and cannot yet be edited.
Chris@394 675
Chris@394 676 - You can now drag-and-drop files (of whatever type) onto SV from
Chris@394 677 other programs such as file managers or web browsers.
Chris@394 678
Chris@394 679 - mp3 files (and Ogg, but they aren't supported on Windows at the
Chris@394 680 moment) are now decoded in a background thread so you can see the
Chris@394 681 start of the track without waiting for the rest to decode.
Chris@394 682
Chris@394 683 - Mac builds of SV can now load AAC/mp4 files and anything else
Chris@394 684 supported by QuickTime.
Chris@394 685
Chris@394 686 - There is now an option to resample audio files on import if they
Chris@394 687 don't match the samplerate of the first file loaded. By default this
Chris@394 688 is switched off, as it affects the visible waveform. The default
Chris@394 689 behaviour is unchanged (play at the wrong rate). There is still no
Chris@394 690 option to handle multiple rates "correctly" (i.e. by resampling
Chris@394 691 on playback and showing the waveforms at different resolutions
Chris@394 692 according to each one's underlying rate) and there probably never
Chris@394 693 will be.
Chris@394 694
Chris@394 695 - SV can now open .m3u playlist files, though it's a hazardous thing
Chris@394 696 to do as it simply loads all the files in the playlist at once.
Chris@394 697
Chris@394 698 - SV now has various options for how to number tapped time instants
Chris@394 699 (bar/beat, plain counter, time in seconds, tempo etc).
Chris@394 700
Chris@394 701 - The official builds use Qt 4.3, which fixes some nasty
Chris@394 702 bugs in the file dialog that the version 1.0 builds suffered from.
Chris@394 703
