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