Chris@2002 1
Chris@2002 2 Changes in Sonic Visualiser 3.2 since the previous release 3.1.1:
Chris@2002 3
Chris@2048 4 - Add ability to zoom closer than one sample per pixel, so as to see
Chris@2048 5 the interpolated signal level between samples
Chris@2048 6
Chris@2110 7 - Add oversampling control to the spectrogram and spectrum layers
Chris@2110 8
Chris@2110 9 - Highlight and label frequency peaks in the spectrum as the mouse
Chris@2110 10 rolls over them, when enabled in the parameter area
Chris@2110 11
Chris@2002 12 - Add feature to convert and import audio from a CSV data file
Chris@2002 13
Chris@2048 14 - Add some new colour maps, and restore the old Blue on Black one
Chris@2048 15
Chris@2110 16 - Speed up spectrum rendering at high resolutions
Chris@2110 17
Chris@2048 18 - Fix failure to pass Nyquist bins correctly to
Chris@2048 19 frequency-domain-input Vamp plugins in some circumstances
Chris@2048 20
Chris@2110 21 - Fix sometimes incorrect shortcut associations for new-layer menu
Chris@2110 22 items
Chris@2110 23

Chris@2110 25
cannam@1948 26
cannam@1948 27 Changes in Sonic Visualiser 3.1.1 (Aug 2018) since the previous release 3.1:
cannam@1948 28
cannam@1948 29 - Fix failure to record correctly into an empty session with certain
cannam@1948 30 audio drivers
cannam@1948 31
Chris@1958 32 - Fix failure to run LADSPA plugins at all, except with some unusual
Chris@1958 33 path layouts
Chris@1958 34
Chris@1958 35 - Fix failure to silence sonified notes when rewinding backwards or
Chris@1958 36 jumping back from a loop endpoint
Chris@1958 37
cannam@1948 38 - Fix macOS .dmg image so as to use older HFS+ filesystem for compatibility
cannam@1948 39
Chris@1871 40
Chris@1932 41 Changes in Sonic Visualiser 3.1 (July 2018) since the previous release 3.0.3:
Chris@1871 42
Chris@1871 43 - Add Plugins tab to Preferences dialog, from which you can review
Chris@1871 44 the plugin load paths and see which plugins were loaded from which
Chris@1871 45 locations, and also customise load paths (though the various path
Chris@1871 46 environment variables are still supported)
Chris@1871 47
Chris@1935 48 - Stream the export of audio data and other CSV data so that
Chris@1935 49 very large exports don't hang the UI or run us out of memory
Chris@1935 50 (thanks to Lucas Thompson)
Chris@1935 51
Chris@1935 52 - Ensure vertical scale appears for auto-align layers when there is
Chris@1935 53 nothing else to auto-align them to
Chris@1935 54
Chris@1871 55 - Fix another long-standing Windows-platform wide-char/utf8
Chris@1871 56 conversion problem, with environment variable naming and contents
Chris@1871 57
Chris@1871 58 - Improve handling of incomplete session loads, i.e. situations where
Chris@1871 59 the audio files referred to by a session could not be found -
Chris@1871 60 previously the session could be re-saved immediately thus losing
Chris@1871 61 the audio reference; now at least we disable Save (enabling only
Chris@1871 62 Save As) and show a warning
Chris@1871 63
Chris@1871 64 - Update pane and layer menu shortcuts so that the
Chris@1871 65 waveform/spectrogram/etc shortcuts (Shift+G etc) operate on the
Chris@1871 66 source model in the currently-selected pane rather than the main
Chris@1871 67 model. This is a backward-incompatible change but is a far more
Chris@1871 68 intuitive way for the function to work
Chris@1871 69
Chris@1935 70 - Use dark background for bright colours in time-value/note/etc
Chris@1935 71 layers as well as e.g. waveforms - this is how it was always
Chris@1935 72 "intended to" work, but it is a backward-incompatible change
Chris@1935 73
Chris@1871 74 - Make "Select All" select the whole span of everything that exists,
Chris@1871 75 not just the main model
Chris@1871 76
Chris@1871 77 - Add horizontal scale to Spectrum layer
Chris@1871 78
Chris@1871 79 - Improve spacing and labelling of vertical log scales
Chris@1871 80
Chris@1871 81 - Update build system for better Cap'n Proto version support and to
Chris@1871 82 use Repoint for code management in the repository
Chris@1871 83
Chris@1871 84 - Various other bug fixes
Chris@1871 85
Chris@1702 86
Chris@1702 87 Changes in Sonic Visualiser 3.0.3 (May 2017) since the previous release 3.0.2:
Chris@1702 88
Chris@1702 89 - Improve decisions about where and how to label vertical scales
Chris@1702 90
Chris@1702 91 - Update build support material and documentation to reflect the
Chris@1702 92 official release of Cap'n Proto 0.6 (which we can now use rather
Chris@1702 93 than depending on git builds)
Chris@1702 94
Chris@1669 95
Chris@1669 96 Changes in Sonic Visualiser 3.0.2 (Mar 2017) since the previous release 3.0.1:
Chris@1669 97
Chris@1669 98 - Fix crash when changing parameters for spectrum view
Chris@1669 99
Chris@1669 100 - Fix incorrect measure tool crosshairs in spectrum view
Chris@1669 101
Chris@1669 102 - Update Russian and Czech UI translations (thanks to Alexandre Prokoudine
Chris@1669 103 and Pavel Fric respectively)
Chris@1702 104
Chris@1658 105
Chris@1658 106 Changes in Sonic Visualiser 3.0.1 (Mar 2017) since the previous release 3.0:
Chris@1658 107
Chris@1658 108 - Fix crashes with MIDI devices and speedup/slowdown control on Windows
Chris@1661 109
Chris@1658 110 - Update MIDI input driver layer
Chris@1447 111
Chris@1661 112
Chris@1624 113 Changes in Sonic Visualiser 3.0 (Mar 2017) since the previous release 2.5:
Chris@1447 114
Chris@1516 115 - Add ability to record audio, and ability to change the audio device
Chris@1516 116 for playback or recording in the preferences
Chris@1447 117
Chris@1447 118 - Add complete support for high-resolution (Hi-DPI or retina)
Chris@1511 119 displays, including for layer data rendering as well as UI controls
Chris@1511 120 and icons. This makes the biggest difference when using a retina
Chris@1511 121 Mac, on which previous versions did not render layer data at retina
Chris@1447 122 resolution, but it also improves scaling and rendering of UI
Chris@1447 123 elements on Hi-DPI displays on Windows and Linux
Chris@1447 124
Chris@1451 125 - Add ability to export scalable (SVG) image files
Chris@1451 126
Chris@1447 127 - Run plugins in a separate process, so that if a plugin crashes, it
Chris@1447 128 no longer brings down Sonic Visualiser with it. In every other
Chris@1447 129 respect the behaviour should be unchanged
Chris@1447 130
Chris@1447 131 - Scan plugins on startup in a separate process, and report on any
Chris@1447 132 that crash or won't load
Chris@1447 133
Chris@1527 134 - Add ability to open, display, and analyse very long audio files (of
Chris@1527 135 more than 2^32 sample frames)
Chris@1527 136
Chris@1447 137 - Change mp3 file loading so as to compensate for encoder/decoder
Chris@1447 138 delay and padding (using "gapless playback" logic). While this is a
Chris@1447 139 real improvement, unfortunately it does mean that the initial
Chris@1447 140 padding in mp3 file load has changed from previous versions, which
Chris@1447 141 may mean some sessions saved in previous versions are no longer
Chris@1447 142 correctly aligned. It's not a great idea to use mp3 as a file
Chris@1447 143 format of record, because of differences like this between
Chris@1447 144 decoders. The previous behaviour is still available as a preference.
Chris@1447 145
Chris@1470 146 - Add new Hybrid normalisation type for spectrogram and colour 3d
Chris@1470 147 plot layers. This normalises each column to its peak value and then
Chris@1470 148 scales the normalised values by the log of the peak in order to
Chris@1470 149 restore some distinction in scale between columns with different
Chris@1470 150 levels. It can provide quite visually clear results.
Chris@1470 151
Chris@1447 152 - Add function to subdivide time instant layers into regular
Chris@1447 153 intervals (and its inverse)
Chris@1447 154
Chris@1447 155 - Add new preference for default colour scales
Chris@1447 156
Chris@1578 157 - Add a basic ability to zoom (in the frequency axis) to the spectrum
Chris@1624 158
Chris@1447 159 - Switch to using combined level/pan controls in layer property boxes
Chris@1447 160 and for the main volume control
Chris@1447 161
Chris@1520 162 - Make CSV file reader better able to handle files with varying
Chris@1520 163 numbers of columns
Chris@1520 164
Chris@1516 165 - Fix a number of problems on Windows with loading and saving some
Chris@1516 166 file formats to filenames not representable in system codepage
Chris@1516 167
Chris@1520 168 - Add "What's New" dialog
Chris@1520 169
Chris@1527 170 - Finally switch the Windows build to 64-bit by default (with
Chris@1447 171 adapters to run either 32- or 64-bit plugins)
Chris@1451 172
Chris@1447 173
Chris@1520 174 Changes in Sonic Visualiser 2.5 (Oct 2015) since the previous release 2.4.1:
Chris@1072 175
Chris@1072 176 - Add unit-converter dialog, for converting between various pitch and
Chris@1072 177 timing units
Chris@1072 178
Chris@1072 179 - Fix failure to reload note layers from session file
Chris@1072 180
Chris@1072 181 - Use a more sensible scale for the play-speed dial
Chris@1072 182
Chris@1072 183 - Fix crash when importing very wide CSV files
Chris@1072 184
Chris@1072 185 - Fix generation of wrong layer type from some CSV files
Chris@1072 186
Chris@1072 187 - Fix failure to export last instant in a time-instant layer
Chris@1072 188
Chris@1457 189
Chris@1520 190 Changes in Sonic Visualiser 2.4.1 (Oct 2014) since the previous release 2.4:
Chris@876 191
Chris@876 192 - Fix a crash when rendering certain colour 3d plot layers
Chris@716 193
Chris@1457 194
Chris@1520 195 Changes in Sonic Visualiser 2.4 (Sep 2014) since the previous release 2.3:
Chris@714 196
Chris@776 197 - Add support for left/right scrolling using a two-finger touchpad
Chris@776 198 gesture (where available)
Chris@776 199
Chris@716 200 - Make the octave numbering into a configurable option, and change
Chris@716 201 the default. Previously Sonic Visualiser labelled middle-C as "C3";
Chris@716 202 now it labels middle-C as "C4", a more common standard in the world
Chris@776 203 outside MIDI sequencer software. The previous system is available
Chris@776 204 as an option in the Preferences. This affects only the visible
Chris@776 205 labels: there is no change to analysis or to the file format
Chris@714 206
Chris@714 207 - Sonify time-value layers. Any time-value curve whose scale unit is
Chris@714 208 set to Hz will now acquire a playback toggle control; this control
Chris@714 209 is off by default, but if it is switched on, the curve will be
Chris@714 210 played back using a variable-frequency sound generator
Chris@714 211
Chris@714 212 - Add support for playback of note layers with non-MIDI frequencies
Chris@714 213 (formerly the note playback was limited to exact MIDI pitch)
Chris@714 214
Chris@714 215 - Change the default playback sample for note layers from piano to an
Chris@714 216 electric piano with sustain. The piano sample is still available,
Chris@714 217 and any sessions saved using it should continue to use it
Chris@714 218
Chris@867 219 - Add a cancel button for Vamp plugin processing: currently,
Chris@867 220 cancelling a transform results in a part-complete layer rather than
Chris@867 221 removing the results
Chris@867 222
Chris@790 223 - Add keyboard shortcuts to cycle the current layer (in addition to
Chris@790 224 the existing ones to cycle the current pane)
Chris@790 225
Chris@790 226 - Fix various bugs related to layer ordering: layer tabs re-ordering
Chris@790 227 themselves randomly when new layer added, layers being ordered
Chris@791 228 randomly when saving and reloading a session
Chris@790 229
Chris@848 230 - Fix incorrect interaction with non-Unicode usernames when creating
Chris@848 231 temporary and template directories on Windows
Chris@848 232
Chris@714 233 - Shade the start and end of the main audio file, to make them easier
Chris@714 234 to see for files that start or end in silence
Chris@714 235
Chris@714 236 - Speed up rendering and scrolling in time-value layers
Chris@714 237
Chris@714 238 - Make it possible to import CSV files directly into Note layers by
Chris@714 239 adding Pitch as a data type in the CSV file import dialog
Chris@675 240
Chris@856 241 - Fix play pointer jump to wrong frame when clicking on row in the
Chris@856 242 layer edit dialog
Chris@856 243
Chris@848 244 - Fix problems with keyboard shortcuts when using Qt5 on OS/X. This
Chris@848 245 is the first release in which the official builds use Qt5 for all
Chris@848 246 platforms.
Chris@848 247
Chris@675 248
Chris@1520 249 Changes in Sonic Visualiser 2.3 (Dec 2013) since the previous release 2.2:
Chris@675 250
Chris@675 251 - Add a startup welcome dialog that also explains what SV makes
Chris@675 252 network connections for and allows user to forbid them
Chris@675 253
Chris@675 254 - Add "Export Audio Data" feature
Chris@675 255
Chris@675 256 - Show piano keyboard scale in note and time-value layers as well
Chris@675 257 as spectrogram, where vertical scale is log Hz; also show
Chris@675 258 numerical scale in note and region layers when not auto-aligned
Chris@675 259
Chris@675 260 - Speed up CSV file import and avoid showing crazily wide window
Chris@675 261 for CSV file format dialog when file has lots of columns
Chris@675 262
Chris@675 263 - Fix incorrectly saved window geometry when exiting from maximised
Chris@675 264 state
Chris@675 265
Chris@675 266 - Reduce number of timer wakeups when idle
Chris@675 267
Chris@675 268 - Add American English translation and make choice of translation
Chris@675 269 into a preference (defaulting to system locale)
Chris@675 270
Chris@675 271 - Permit installation to non-default location with Windows installer
Chris@675 272 build
Chris@714 273
Chris@608 274
Chris@1520 275 Changes in Sonic Visualiser 2.2 (July 2013) since the previous release 2.1:
Chris@608 276
Chris@608 277 - Build with support for hidpi ("retina") text on OS/X
Chris@675 278
Chris@608 279 - Fix very slow analysis when using Ogg or FLAC files decoded
Chris@608 280 via libsndfile
Chris@675 281
Chris@608 282 - Fix inaccurate scale auto-align between time-value layers and
Chris@608 283 others
Chris@675 284
Chris@608 285 - Fix failure to open files specified on command line (or via
Chris@608 286 Open With) on Windows
Chris@675 287
Chris@608 288 - Reset cyclical counters and switch back to navigate mode when
Chris@608 289 a new session is started
Chris@579 290
Chris@675 291
Chris@1520 292 Changes in Sonic Visualiser 2.1 (May 2013) since the previous release 2.0.1:
Chris@579 293
Chris@579 294 - Fix incorrect handling of FixedSampleRate outputs (Vamp SDK fix)
Chris@675 295
Chris@579 296 - Make it easier to see results from transforms that return a single point
Chris@675 297
Chris@579 298 - Make labelling clearer on time-value layers
Chris@675 299
Chris@579 300 - Add discrete-curve mode for time-value layers (for curves with gaps)
Chris@675 301
Chris@579 302 - Update code to build against Qt5
Chris@523 303
Chris@675 304
Chris@523 305 Changes in Sonic Visualiser 2.0.1 since the previous release 2.0:
Chris@523 306
Chris@523 307 - Fix incorrect samplerate in reading m4a files on OS/X
Chris@512 308
Chris@675 309
Chris@1520 310 Changes in Sonic Visualiser 2.0 (July 2012) since the previous release 1.9:
Chris@512 311
Chris@512 312 - Support 64-bit builds on OS/X (using CoreAudio instead of
Chris@512 313 obsolete QuickTime audio file reader)
Chris@512 314
Chris@512 315 - Simplify RDF reading and fix some bugs. Now requires Dataquay
Chris@512 316 (http://breakfastquay.com/dataquay/) rather than using Redland
Chris@512 317 directly. Release builds use Sord/Serd rather than Redland
Chris@512 318
Chris@512 319 - Add a fullscreen mode on the F11 key
Chris@471 320
Chris@675 321
Chris@1520 322 Changes in Sonic Visualiser 1.9 (Oct 2011) since the previous release 1.8:
Chris@471 323
Chris@471 324 - Add session templates; save session as template; apply template to
Chris@471 325 session
Chris@471 326
Chris@471 327 - Tidy up the file open logic so as to remove the dialog asking how
Chris@471 328 to open a file, where possible
Chris@471 329
Chris@471 330 - Various bug fixes.
Chris@394 331
Chris@675 332
Chris@1520 333 Changes in Sonic Visualiser 1.8 (Apr 2011) since the previous release 1.7.2:
Chris@394 334
Chris@394 335 - Sonic Visualiser now registers as a file type handler on OS/X,
Chris@394 336 providing better integration with the desktop generally (Dan Stowell)
Chris@394 337
Chris@394 338 - There is a new function to toggle all Time Rulers at once (key #)
Chris@394 339
Chris@407 340 - The CSV import dialog has been overhauled, allowing more flexible
Chris@407 341 selection of purpose for each column
Chris@407 342
Chris@394 343 - Text overlays are now easier to read on dark backgrounds
Chris@394 344
Chris@394 345 - Hidden layers are now ignored when exporting an image (Dan Stowell)
Chris@394 346
Chris@394 347 - A crash when starting a new session or exiting the application
Chris@394 348 after loading a session with saved alignment data has been fixed
Chris@394 349
Chris@394 350 - The duplication of right-button menu functions when multiple files
Chris@394 351 were loaded has been fixed
Chris@394 352
Chris@394 353 - The layer-add menu functions now have shortcuts (Dan Stowell)
Chris@394 354
Chris@394 355 - The codebase has been reorganised into libraries and a configure
Chris@394 356 step added. It should be easier to build and maintain on OS/X and
Chris@394 357 Linux than previously, although it won't make much difference on
Chris@394 358 Windows.
Chris@394 359
Chris@397 360 - A Czech translation is now included (thanks to Pavel Fric).
Chris@397 361
Chris@675 362
Chris@1520 363 Changes in Sonic Visualiser 1.7.2 (May 2010) since the previous release 1.7.1:
Chris@394 364
Chris@394 365 - The time-value layer now has an origin line and an option to
Chris@394 366 show derivatives (change from one point to the next) rather than
Chris@394 367 raw values
Chris@394 368
Chris@394 369 - A static initialiser race has been fixed, possibly fixing an
Chris@394 370 occasional crash on startup in Windows
Chris@394 371
Chris@394 372 - A crash when pressing Play straight after New Session has been
Chris@394 373 fixed
Chris@394 374
Chris@675 375
Chris@1520 376 Changes in Sonic Visualiser 1.7.1 (Oct 2009) since the previous release 1.7:
Chris@394 377
Chris@394 378 - The RDF importer does a better job of assigning labels to layers,
Chris@394 379 layers to panes, and values to labelled regions
Chris@394 380
Chris@394 381 - Interactive editing in the Text layer benefits from the same
Chris@394 382 improvements as made in 1.7 to Note and Region layers
Chris@394 383
Chris@394 384 - The layer data editor window has a text search feature
Chris@394 385
Chris@394 386 - The main window status bar now shows the last label to have passed
Chris@394 387 the playback position in the current layer, at the right end of the
Chris@394 388 status bar
Chris@394 389

Chris@1520 393 Changes in Sonic Visualiser 1.7 (Sep 2009) since the previous release 1.6:
Chris@394 394
Chris@394 395 - A new "Insert Item At Selection" function on the Edit menu
Chris@394 396 can be used to create Note and Region layer items whose time
Chris@394 397 extents correspond to the current selection(s)
Chris@394 398
Chris@394 399 - Interactively editing points in the Note and Region layers
Chris@394 400 now works much more smoothly
Chris@394 401
Chris@394 402 - SV can now import MIDI files that use SMPTE timecode for event
Chris@394 403 timing (importing MIDI files using with the more common
Chris@394 404 timebase-based timing was already supported)
Chris@394 405
Chris@394 406 - Time values throughout the display may optionally be shown in
Chris@394 407 seconds and frames at various frame rates
Chris@1520 408
Chris@394 409 - A crash on exit in Windows has been fixed
Chris@394 410
Chris@394 411 - A very unobtrusive user survey is now included

Chris@394 417
Chris@394 418 - The Colour 3D Plot layer now supports logarithmic vertical
Chris@394 419 scale and linear interpolation options.
Chris@394 420
Chris@394 421 - A new colour scheme (High Gain) has been added for spectrogram
Chris@394 422 and Colour 3D Plot, which improves readability for some data.
Chris@394 423
Chris@394 424 - Further performance improvements have been made to Colour 3D
Chris@394 425 Plot.
Chris@394 426
Chris@394 427 - Various other bug fixes.
Chris@394 428
Chris@675 429
Chris@1520 430 Changes in Sonic Visualiser 1.5 (Mar 2009) since the previous release 1.4:
Chris@394 431
Chris@394 432 - You can now insert time instants, time values, and notes using
Chris@394 433 a MIDI device during playback. If a time value or note layer is
Chris@394 434 current it will be used for insertion (giving a value equal to
Chris@394 435 the pitch class, or the played note, respectively); otherwise an
Chris@394 436 existing or new time instants layer will be used just as it is
Chris@394 437 when inserting instants using the PC keyboard. Using a MIDI
Chris@394 438 device should give better timing than using the PC keyboard.
Chris@394 439
Chris@394 440 - There is a new Activity Log window with a (purely informative) list
Chris@394 441 of events and user interactions that happen while SV is running.
Chris@394 442
Chris@394 443 - The spectrogram has somewhat improved graphical scaling, and
Chris@394 444 this is now the default (being much faster than the 4x oversampled
Chris@394 445 method). The previous default is still available as a preference.
Chris@394 446
Chris@394 447 - Visualisation of very dense colour plots (such as spectrograms
Chris@394 448 calculated by plugins) is substantially faster in this release.
Chris@394 449
Chris@394 450 - Spectrogram display is now faster in many circumstances.
Chris@394 451
Chris@394 452 - Alignment using the MATCH plugin is faster on OS/X than before.
Chris@394 453
Chris@394 454 - SV will take into account RDF plugin descriptions, if available,
Chris@394 455 in order to make somewhat better decisions about display of plugin
Chris@394 456 outputs (for example, placing segmentation data into a layer with
Chris@394 457 segmentation plot type).
Chris@394 458
Chris@394 459 - You can now switch layers by clicking on the spare area at the left
Chris@394 460 end of the pane that is also used for the current pane indicator.
Chris@394 461
Chris@394 462 - The vertical black lines dividing segments in the time value
Chris@394 463 layer's segmentation plot style are now optional.
Chris@394 464
Chris@394 465 - Several widget layout bugs on OS/X have been fixed.
Chris@394 466
Chris@394 467 - Several serious crashing, deadlock, and data corruption bugs have
Chris@394 468 been fixed.
Chris@394 469
Chris@394 470
Chris@1520 471 Changes in Sonic Visualiser 1.4 (Dec 2008) since the previous release 1.3:
Chris@394 472
Chris@394 473 - SV now has a Region layer type, used for display of features with
Chris@394 474 durations. It also supports Vamp v2.0 plugins that provide durations
Chris@394 475 for features.
Chris@394 476
Chris@394 477 - Layer data can now be imported from RDF described using the Audio
Chris@394 478 Features Ontology, as well as from the existing text file types. SV
Chris@394 479 can also export annotation layer data to RDF/Turtle, although in a
Chris@394 480 somewhat simplistic manner at present.
Chris@394 481
Chris@394 482 - You can search for transforms by text in the new "Find a Transform"
Chris@394 483 dialog. This searches both installed plugins, and plugins that have
Chris@394 484 not been installed but that have descriptions available on the
Chris@394 485 semantic web.
Chris@394 486
Chris@394 487 - You can now zoom and scroll vertically in the time-value, note,
Chris@394 488 and colour 3d plot layers.
Chris@394 489
Chris@394 490 - Sonic Visualiser can now load sessions from uncompressed XML files
Chris@394 491 as well as its own compressed-XML .sv format. Files with extension
Chris@394 492 .xml that contain suitable session data will be loaded as sessions.
Chris@394 493 Note that .xml extension files still do not show up in the default
Chris@394 494 file load filter. This is intentional, as there may be any kind of
Chris@394 495 data in them -- if you want to load uncompressed session files from
Chris@394 496 XML, you need to know you're doing it.
Chris@394 497
Chris@394 498 - Several crashes and other bugs have been fixed.
Chris@394 499
Chris@675 500
Chris@1520 501 Changes in Sonic Visualiser 1.3 (Jul 2008) since the previous release 1.2:
Chris@394 502
Chris@394 503 - There is a new spreadsheet-style data viewer and editor for
Chris@394 504 viewing and editing the data in some types of annotation layer.
Chris@394 505
Chris@394 506 - Alignments are now saved to the session file.
Chris@394 507
Chris@394 508 - The spectrogram layer is usually somewhat faster than it was.
Chris@394 509
Chris@394 510 - You can now hold Shift while dragging to move an item, in order
Chris@394 511 to override the initial drag resistance introduced in 1.2.
Chris@394 512
Chris@394 513 - The gross mis-labelling of time lines in the ruler has been fixed.
Chris@394 514
Chris@394 515 - There is a new, somewhat provisional PulseAudio output driver.
Chris@394 516
Chris@394 517 - Several other bug fixes.
Chris@394 518
Chris@675 519
Chris@1520 520 Changes in Sonic Visualiser 1.2 (Feb 2008) since the previous release 1.0:
Chris@394 521
Chris@394 522 - SV now supports time-alignment of multiple performances of a work
Chris@394 523 loaded at the same time. This option is enabled when the MATCH Vamp
Chris@394 524 plugin is installed. When alignment is switched on and more than one
Chris@394 525 audio file is open, SV will assume that all open files are
Chris@394 526 differently timed performances of the same work, and will calculate
Chris@394 527 time alignments for them. Playback will then play only a single file
Chris@394 528 at a time, and the playback cursors in other files will track at the
Chris@394 529 varying speeds to try to ensure that each is at the same point in the
Chris@394 530 underlying score. This enables effective comparison of several such
Chris@394 531 files, as well as a meaningful way to switch from one performance to
Chris@394 532 another during playback (ensuring that the switch happens at the
Chris@394 533 correct point in the performance being switched to).
Chris@394 534
Chris@394 535 - There is a new Image layer, which can display images from the
Chris@394 536 local filesystem or retrieved via HTTP or FTP.
Chris@394 537
Chris@394 538 - A new measurement tool has been added. With the measurement tool
Chris@394 539 selected, dragging in a pane draws a rectangle labelled with the
Chris@394 540 scale values for its start and end corners and its size. You can
Chris@394 541 have any number of measurements present at once; they are associated
Chris@394 542 with the top layer, their scale values depend on the scale for that
Chris@394 543 layer, and they are only shown when that layer is at the top and the
Chris@394 544 measurement tool is active. Measurements are saved and reloaded in
Chris@394 545 the session file. Drawing measurements can be undone and redone, and
Chris@394 546 a measurement can be deleted by hitting Del when highlighted. Note
Chris@394 547 that the measurement tool shows the scale values associated with the
Chris@394 548 pixel positions of the mouse when dragging, not any values associated
Chris@394 549 with actual features present in the audio or its analysis (e.g. the
Chris@394 550 values are not rounded to the nearest spectrogram bin).
Chris@394 551
Chris@394 552 - You can double-click using the measurement tool in the spectrogram
Chris@394 553 to get an instant measurement rectangle for a feature. This is a
Chris@394 554 purely graphical feature that works by calculating the boundary of a
Chris@394 555 contiguous region of pixels "similar to" the one you double-clicked
Chris@394 556 on; it does not use audio analysis. Adjusting the gain and colour
Chris@394 557 scheme etc of the spectrogram will (by design) affect the
Chris@394 558 measurements obtained this way.
Chris@394 559
Chris@394 560 - The spectrum can now optionally show frequency estimates of peaks
Chris@394 561 aligned with a piano keyboard along the horizontal axis (this needs
Chris@394 562 some refinement).
Chris@394 563
Chris@394 564 - The harmonic cursor in the spectrogram has moved from the Select
Chris@394 565 tool to the Measurement tool. There is now a similar harmonic cursor
Chris@394 566 in the spectrum. Both of them show more information as text
Chris@394 567 alongside the cursor than previously.
Chris@394 568
Chris@394 569 - There is a new Erase tool for erasing individual points from an
Chris@394 570 editable layer.
Chris@394 571
Chris@394 572 - Several keyboard shortcuts have changed -- all of the Alt+key
Chris@394 573 shortcuts now either use Ctrl or a plain keypress with no modifier,
Chris@394 574 to avoid clashes with window manager shortcuts and to make them
Chris@394 575 easier to use and remember
Chris@394 576
Chris@394 577 - The playback controls are now in a Playback menu as well as the
Chris@394 578 toolbar.
Chris@394 579
Chris@394 580 - There is a new key and mouse control reference under Help (or press
Chris@394 581 F2).
Chris@394 582
Chris@394 583 - You can double-click on a pane in navigate mode to jump to a time.
Chris@394 584
Chris@394 585 - All of the single-colour layers (waveform, time values etc) now
Chris@394 586 allow you to define your own colours as well as using the built-in
Chris@394 587 set. The colour of a layer is now shown next to its name on the pane.
Chris@394 588
Chris@394 589 - When you add a new single-colour layer it will use a default colour
Chris@394 590 that is not yet in use in another layer (if there is one).
Chris@394 591
Chris@394 592 - Single-colour layers can now optionally have black backgrounds (with
Chris@394 593 a set of lighter colours in the default colour palette that use black
Chris@394 594 backgrounds by default).
Chris@394 595
Chris@394 596 - There's a new Printer colour scheme in the spectrogram with only a
Chris@394 597 small number of grey shades.
Chris@394 598
Chris@394 599 - Vertical zoom in a log-scaled spectrogram is much more intuitive;
Chris@394 600 it now leaves the point that was in the centre of the visible area in
Chris@394 601 the centre after zoom, instead of the point that was in the centre of
Chris@394 602 the linear range corresponding to the visible area.
Chris@394 603
Chris@394 604 - You can now turn a colour 3d plot layer upside down by clicking the
Chris@394 605 Invert Vertical Scale button.
Chris@394 606
Chris@394 607 - There's a new Layer Summary window which shows the panes and
Chris@394 608 layer data in a tree layout. This is very simplistic at the moment.
Chris@394 609
Chris@394 610 - Each pane now has an [X] button at its top left, which removes that
Chris@394 611 pane when clicked.
Chris@394 612
Chris@394 613 - There's a new Solo play mode toggle button; when active, only the
Chris@394 614 currently selected pane is played. This is also the default when
Chris@394 615 time alignment is in use.
Chris@394 616
Chris@394 617 - Rewind/ffwd now stay confined to the selection if Play Selection is
Chris@394 618 enabled; also, the rewind and ffwd "one step" buttons are now enabled
Chris@394 619 even if there is no time instants layer for them to align to (they
Chris@394 620 align to the time ruler instead and so jump in steps of a size
Chris@394 621 dependent on the zoom level).
Chris@394 622
Chris@394 623 - You can now export note layers to MIDI.
Chris@394 624
Chris@394 625 - MIDI note velocity is partially supported. Note velocity is
Chris@394 626 retained when importing and exporting MIDI and is used in playback,
Chris@394 627 but it is not yet shown in the display and cannot yet be edited.
Chris@394 628
Chris@394 629 - You can now drag-and-drop files (of whatever type) onto SV from
Chris@394 630 other programs such as file managers or web browsers.
Chris@394 631
Chris@394 632 - mp3 files (and Ogg, but they aren't supported on Windows at the
Chris@394 633 moment) are now decoded in a background thread so you can see the
Chris@394 634 start of the track without waiting for the rest to decode.
Chris@394 635
Chris@394 636 - Mac builds of SV can now load AAC/mp4 files and anything else
Chris@394 637 supported by QuickTime.
Chris@394 638
Chris@394 639 - There is now an option to resample audio files on import if they
Chris@394 640 don't match the samplerate of the first file loaded. By default this
Chris@394 641 is switched off, as it affects the visible waveform. The default
Chris@394 642 behaviour is unchanged (play at the wrong rate). There is still no
Chris@394 643 option to handle multiple rates "correctly" (i.e. by resampling
Chris@394 644 on playback and showing the waveforms at different resolutions
Chris@394 645 according to each one's underlying rate) and there probably never
Chris@394 646 will be.
Chris@394 647
Chris@394 648 - SV can now open .m3u playlist files, though it's a hazardous thing
Chris@394 649 to do as it simply loads all the files in the playlist at once.
Chris@394 650
Chris@394 651 - SV now has various options for how to number tapped time instants
Chris@394 652 (bar/beat, plain counter, time in seconds, tempo etc).
Chris@394 653
Chris@394 654 - The official builds use Qt 4.3, which fixes some nasty
Chris@394 655 bugs in the file dialog that the version 1.0 builds suffered from.
Chris@394 656
