Chris@1447 1
Chris@1447 2 Changes in Sonic Visualiser 3.0 since the previous release 2.5:
Chris@1447 3
Chris@1447 4 - Add ability to record audio, and ability to change audio device for
Chris@1447 5 playback or recording in the preferences
Chris@1447 6
Chris@1447 7 - Add complete support for high-resolution (Hi-DPI or retina)
Chris@1447 8 displays, spanning layer data rendering and UI controls and
Chris@1447 9 icons. This makes the biggest difference when using a retina Mac,
Chris@1447 10 on which previous versions did not render layer data at retina
Chris@1447 11 resolution, but it also improves scaling and rendering of UI
Chris@1447 12 elements on Hi-DPI displays on Windows and Linux
Chris@1447 13
Chris@1447 14 - Add ability to open, display, and analyse very long audio files (of
Chris@1447 15 more than 2^32 sample frames)
Chris@1447 16
Chris@1451 17 - Add ability to export scalable (SVG) image files
Chris@1451 18
Chris@1447 19 - Run plugins in a separate process, so that if a plugin crashes, it
Chris@1447 20 no longer brings down Sonic Visualiser with it. In every other
Chris@1447 21 respect the behaviour should be unchanged
Chris@1447 22
Chris@1447 23 - Scan plugins on startup in a separate process, and report on any
Chris@1447 24 that crash or won't load
Chris@1447 25
Chris@1447 26 - Change mp3 file loading so as to compensate for encoder/decoder
Chris@1447 27 delay and padding (using "gapless playback" logic). While this is a
Chris@1447 28 real improvement, unfortunately it does mean that the initial
Chris@1447 29 padding in mp3 file load has changed from previous versions, which
Chris@1447 30 may mean some sessions saved in previous versions are no longer
Chris@1447 31 correctly aligned. It's not a great idea to use mp3 as a file
Chris@1447 32 format of record, because of differences like this between
Chris@1447 33 decoders. The previous behaviour is still available as a preference.
Chris@1447 34
Chris@1447 35 - Add function to subdivide time instant layers into regular
Chris@1447 36 intervals (and its inverse)
Chris@1447 37
Chris@1447 38 - Add new preference for default colour scales
Chris@1447 39
Chris@1447 40 - Switch to using combined level/pan controls in layer property boxes
Chris@1447 41 and for the main volume control
Chris@1447 42
Chris@1447 43 - Finally switch the Windows built to 64-bit by default (with
Chris@1447 44 adapters to run either 32- or 64-bit plugins)
Chris@1451 45
Chris@1447 46
Chris@1072 47 Changes in Sonic Visualiser 2.5 since the previous release 2.4.1:
Chris@1072 48
Chris@1072 49 - Add unit-converter dialog, for converting between various pitch and
Chris@1072 50 timing units
Chris@1072 51
Chris@1072 52 - Fix failure to reload note layers from session file
Chris@1072 53
Chris@1072 54 - Use a more sensible scale for the play-speed dial
Chris@1072 55
Chris@1072 56 - Fix crash when importing very wide CSV files
Chris@1072 57
Chris@1072 58 - Fix generation of wrong layer type from some CSV files
Chris@1072 59
Chris@1072 60 - Fix failure to export last instant in a time-instant layer
Chris@1072 61
Chris@1457 62
Chris@876 63 Changes in Sonic Visualiser 2.4.1 since the previous release 2.4:
Chris@876 64
Chris@876 65 - Fix a crash when rendering certain colour 3d plot layers
Chris@716 66
Chris@1457 67
Chris@714 68 Changes in Sonic Visualiser 2.4 since the previous release 2.3:
Chris@714 69
Chris@776 70 - Add support for left/right scrolling using a two-finger touchpad
Chris@776 71 gesture (where available)
Chris@776 72
Chris@716 73 - Make the octave numbering into a configurable option, and change
Chris@716 74 the default. Previously Sonic Visualiser labelled middle-C as "C3";
Chris@716 75 now it labels middle-C as "C4", a more common standard in the world
Chris@776 76 outside MIDI sequencer software. The previous system is available
Chris@776 77 as an option in the Preferences. This affects only the visible
Chris@776 78 labels: there is no change to analysis or to the file format
Chris@714 79
Chris@714 80 - Sonify time-value layers. Any time-value curve whose scale unit is
Chris@714 81 set to Hz will now acquire a playback toggle control; this control
Chris@714 82 is off by default, but if it is switched on, the curve will be
Chris@714 83 played back using a variable-frequency sound generator
Chris@714 84
Chris@714 85 - Add support for playback of note layers with non-MIDI frequencies
Chris@714 86 (formerly the note playback was limited to exact MIDI pitch)
Chris@714 87
Chris@714 88 - Change the default playback sample for note layers from piano to an
Chris@714 89 electric piano with sustain. The piano sample is still available,
Chris@714 90 and any sessions saved using it should continue to use it
Chris@714 91
Chris@867 92 - Add a cancel button for Vamp plugin processing: currently,
Chris@867 93 cancelling a transform results in a part-complete layer rather than
Chris@867 94 removing the results
Chris@867 95
Chris@790 96 - Add keyboard shortcuts to cycle the current layer (in addition to
Chris@790 97 the existing ones to cycle the current pane)
Chris@790 98
Chris@790 99 - Fix various bugs related to layer ordering: layer tabs re-ordering
Chris@790 100 themselves randomly when new layer added, layers being ordered
Chris@791 101 randomly when saving and reloading a session
Chris@790 102
Chris@848 103 - Fix incorrect interaction with non-Unicode usernames when creating
Chris@848 104 temporary and template directories on Windows
Chris@848 105
Chris@714 106 - Shade the start and end of the main audio file, to make them easier
Chris@714 107 to see for files that start or end in silence
Chris@714 108
Chris@714 109 - Speed up rendering and scrolling in time-value layers
Chris@714 110
Chris@714 111 - Make it possible to import CSV files directly into Note layers by
Chris@714 112 adding Pitch as a data type in the CSV file import dialog
Chris@675 113
Chris@856 114 - Fix play pointer jump to wrong frame when clicking on row in the
Chris@856 115 layer edit dialog
Chris@856 116
Chris@848 117 - Fix problems with keyboard shortcuts when using Qt5 on OS/X. This
Chris@848 118 is the first release in which the official builds use Qt5 for all
Chris@848 119 platforms.
Chris@848 120
Chris@675 121
Chris@675 122 Changes in Sonic Visualiser 2.3 since the previous release 2.2:
Chris@675 123
Chris@675 124 - Add a startup welcome dialog that also explains what SV makes
Chris@675 125 network connections for and allows user to forbid them
Chris@675 126
Chris@675 127 - Add "Export Audio Data" feature
Chris@675 128
Chris@675 129 - Show piano keyboard scale in note and time-value layers as well
Chris@675 130 as spectrogram, where vertical scale is log Hz; also show
Chris@675 131 numerical scale in note and region layers when not auto-aligned
Chris@675 132
Chris@675 133 - Speed up CSV file import and avoid showing crazily wide window
Chris@675 134 for CSV file format dialog when file has lots of columns
Chris@675 135
Chris@675 136 - Fix incorrectly saved window geometry when exiting from maximised
Chris@675 137 state
Chris@675 138
Chris@675 139 - Reduce number of timer wakeups when idle
Chris@675 140
Chris@675 141 - Add American English translation and make choice of translation
Chris@675 142 into a preference (defaulting to system locale)
Chris@675 143
Chris@675 144 - Permit installation to non-default location with Windows installer
Chris@675 145 build
Chris@714 146
Chris@608 147
Chris@608 148 Changes in Sonic Visualiser 2.2 since the previous release 2.1:
Chris@608 149
Chris@608 150 - Build with support for hidpi ("retina") text on OS/X
Chris@675 151
Chris@608 152 - Fix very slow analysis when using Ogg or FLAC files decoded
Chris@608 153 via libsndfile
Chris@675 154
Chris@608 155 - Fix inaccurate scale auto-align between time-value layers and
Chris@608 156 others
Chris@675 157
Chris@608 158 - Fix failure to open files specified on command line (or via
Chris@608 159 Open With) on Windows
Chris@675 160
Chris@608 161 - Reset cyclical counters and switch back to navigate mode when
Chris@608 162 a new session is started
Chris@579 163
Chris@675 164
Chris@579 165 Changes in Sonic Visualiser 2.1 since the previous release 2.0.1:
Chris@579 166
Chris@579 167 - Fix incorrect handling of FixedSampleRate outputs (Vamp SDK fix)
Chris@675 168
Chris@579 169 - Make it easier to see results from transforms that return a single point
Chris@675 170
Chris@579 171 - Make labelling clearer on time-value layers
Chris@675 172
Chris@579 173 - Add discrete-curve mode for time-value layers (for curves with gaps)
Chris@675 174
Chris@579 175 - Update code to build against Qt5
Chris@523 176
Chris@675 177
Chris@523 178 Changes in Sonic Visualiser 2.0.1 since the previous release 2.0:
Chris@523 179
Chris@523 180 - Fix incorrect samplerate in reading m4a files on OS/X
Chris@512 181
Chris@675 182
Chris@512 183 Changes in Sonic Visualiser 2.0 since the previous release 1.9:
Chris@512 184
Chris@512 185 - Support 64-bit builds on OS/X (using CoreAudio instead of
Chris@512 186 obsolete QuickTime audio file reader)
Chris@512 187
Chris@512 188 - Simplify RDF reading and fix some bugs. Now requires Dataquay
Chris@512 189 (http://breakfastquay.com/dataquay/) rather than using Redland
Chris@512 190 directly. Release builds use Sord/Serd rather than Redland
Chris@512 191
Chris@512 192 - Add a fullscreen mode on the F11 key
Chris@471 193
Chris@675 194
Chris@471 195 Changes in Sonic Visualiser 1.9 since the previous release 1.8:
Chris@471 196
Chris@471 197 - Add session templates; save session as template; apply template to
Chris@471 198 session
Chris@471 199
Chris@471 200 - Tidy up the file open logic so as to remove the dialog asking how
Chris@471 201 to open a file, where possible
Chris@471 202
Chris@471 203 - Various bug fixes.
Chris@394 204
Chris@675 205
Chris@394 206 Changes in Sonic Visualiser 1.8 since the previous release 1.7.2:
Chris@394 207
Chris@394 208 - Sonic Visualiser now registers as a file type handler on OS/X,
Chris@394 209 providing better integration with the desktop generally (Dan Stowell)
Chris@394 210
Chris@394 211 - There is a new function to toggle all Time Rulers at once (key #)
Chris@394 212
Chris@407 213 - The CSV import dialog has been overhauled, allowing more flexible
Chris@407 214 selection of purpose for each column
Chris@407 215
Chris@394 216 - Text overlays are now easier to read on dark backgrounds
Chris@394 217
Chris@394 218 - Hidden layers are now ignored when exporting an image (Dan Stowell)
Chris@394 219
Chris@394 220 - A crash when starting a new session or exiting the application
Chris@394 221 after loading a session with saved alignment data has been fixed
Chris@394 222
Chris@394 223 - The duplication of right-button menu functions when multiple files
Chris@394 224 were loaded has been fixed
Chris@394 225
Chris@394 226 - The layer-add menu functions now have shortcuts (Dan Stowell)
Chris@394 227
Chris@394 228 - The codebase has been reorganised into libraries and a configure
Chris@394 229 step added. It should be easier to build and maintain on OS/X and
Chris@394 230 Linux than previously, although it won't make much difference on
Chris@394 231 Windows.
Chris@394 232
Chris@397 233 - A Czech translation is now included (thanks to Pavel Fric).
Chris@397 234
Chris@675 235
Chris@394 236 Changes in Sonic Visualiser 1.7.2 since the previous release 1.7.1:
Chris@394 237
Chris@394 238 - The time-value layer now has an origin line and an option to
Chris@394 239 show derivatives (change from one point to the next) rather than
Chris@394 240 raw values
Chris@394 241
Chris@394 242 - A static initialiser race has been fixed, possibly fixing an
Chris@394 243 occasional crash on startup in Windows
Chris@394 244
Chris@394 245 - A crash when pressing Play straight after New Session has been
Chris@394 246 fixed
Chris@394 247
Chris@675 248
Chris@394 249 Changes in Sonic Visualiser 1.7.1 since the previous release 1.7:
Chris@394 250
Chris@394 251 - The RDF importer does a better job of assigning labels to layers,
Chris@394 252 layers to panes, and values to labelled regions
Chris@394 253
Chris@394 254 - Interactive editing in the Text layer benefits from the same
Chris@394 255 improvements as made in 1.7 to Note and Region layers
Chris@394 256
Chris@394 257 - The layer data editor window has a text search feature
Chris@394 258
Chris@394 259 - The main window status bar now shows the last label to have passed
Chris@394 260 the playback position in the current layer, at the right end of the
Chris@394 261 status bar
Chris@394 262
Chris@394 263 - The Russian translation has been updated (thanks Alexandre)
Chris@394 264
Chris@675 265
Chris@394 266 Changes in Sonic Visualiser 1.7 since the previous release 1.6:
Chris@394 267
Chris@394 268 - A new "Insert Item At Selection" function on the Edit menu
Chris@394 269 can be used to create Note and Region layer items whose time
Chris@394 270 extents correspond to the current selection(s)
Chris@394 271
Chris@394 272 - Interactively editing points in the Note and Region layers
Chris@394 273 now works much more smoothly
Chris@394 274
Chris@394 275 - SV can now import MIDI files that use SMPTE timecode for event
Chris@394 276 timing (importing MIDI files using with the more common
Chris@394 277 timebase-based timing was already supported)
Chris@394 278
Chris@394 279 - Time values throughout the display may optionally be shown in
Chris@394 280 seconds and frames at various frame rates
Chris@394 281
Chris@394 282 - A crash on exit in Windows has been fixed
Chris@394 283
Chris@394 284 - A very unobtrusive user survey is now included
Chris@394 285
Chris@394 286 - Various other bug fixes.
Chris@394 287
Chris@675 288
Chris@394 289 Changes in Sonic Visualiser 1.6 since the previous release 1.5:
Chris@394 290
Chris@394 291 - The Colour 3D Plot layer now supports logarithmic vertical
Chris@394 292 scale and linear interpolation options.
Chris@394 293
Chris@394 294 - A new colour scheme (High Gain) has been added for spectrogram
Chris@394 295 and Colour 3D Plot, which improves readability for some data.
Chris@394 296
Chris@394 297 - Further performance improvements have been made to Colour 3D
Chris@394 298 Plot.
Chris@394 299
Chris@394 300 - Various other bug fixes.
Chris@394 301
Chris@675 302
Chris@394 303 Changes in Sonic Visualiser 1.5 since the previous version 1.4:
Chris@394 304
Chris@394 305 - You can now insert time instants, time values, and notes using
Chris@394 306 a MIDI device during playback. If a time value or note layer is
Chris@394 307 current it will be used for insertion (giving a value equal to
Chris@394 308 the pitch class, or the played note, respectively); otherwise an
Chris@394 309 existing or new time instants layer will be used just as it is
Chris@394 310 when inserting instants using the PC keyboard. Using a MIDI
Chris@394 311 device should give better timing than using the PC keyboard.
Chris@394 312
Chris@394 313 - There is a new Activity Log window with a (purely informative) list
Chris@394 314 of events and user interactions that happen while SV is running.
Chris@394 315
Chris@394 316 - The spectrogram has somewhat improved graphical scaling, and
Chris@394 317 this is now the default (being much faster than the 4x oversampled
Chris@394 318 method). The previous default is still available as a preference.
Chris@394 319
Chris@394 320 - Visualisation of very dense colour plots (such as spectrograms
Chris@394 321 calculated by plugins) is substantially faster in this release.
Chris@394 322
Chris@394 323 - Spectrogram display is now faster in many circumstances.
Chris@394 324
Chris@394 325 - Alignment using the MATCH plugin is faster on OS/X than before.
Chris@394 326
Chris@394 327 - SV will take into account RDF plugin descriptions, if available,
Chris@394 328 in order to make somewhat better decisions about display of plugin
Chris@394 329 outputs (for example, placing segmentation data into a layer with
Chris@394 330 segmentation plot type).
Chris@394 331
Chris@394 332 - You can now switch layers by clicking on the spare area at the left
Chris@394 333 end of the pane that is also used for the current pane indicator.
Chris@394 334
Chris@394 335 - The vertical black lines dividing segments in the time value
Chris@394 336 layer's segmentation plot style are now optional.
Chris@394 337
Chris@394 338 - Several widget layout bugs on OS/X have been fixed.
Chris@394 339
Chris@394 340 - Several serious crashing, deadlock, and data corruption bugs have
Chris@394 341 been fixed.
Chris@394 342
Chris@394 343
Chris@394 344 New features in Sonic Visualiser 1.4 since the previous version 1.3:
Chris@394 345
Chris@394 346 - SV now has a Region layer type, used for display of features with
Chris@394 347 durations. It also supports Vamp v2.0 plugins that provide durations
Chris@394 348 for features.
Chris@394 349
Chris@394 350 - Layer data can now be imported from RDF described using the Audio
Chris@394 351 Features Ontology, as well as from the existing text file types. SV
Chris@394 352 can also export annotation layer data to RDF/Turtle, although in a
Chris@394 353 somewhat simplistic manner at present.
Chris@394 354
Chris@394 355 - You can search for transforms by text in the new "Find a Transform"
Chris@394 356 dialog. This searches both installed plugins, and plugins that have
Chris@394 357 not been installed but that have descriptions available on the
Chris@394 358 semantic web.
Chris@394 359
Chris@394 360 - You can now zoom and scroll vertically in the time-value, note,
Chris@394 361 and colour 3d plot layers.
Chris@394 362
Chris@394 363 - Sonic Visualiser can now load sessions from uncompressed XML files
Chris@394 364 as well as its own compressed-XML .sv format. Files with extension
Chris@394 365 .xml that contain suitable session data will be loaded as sessions.
Chris@394 366 Note that .xml extension files still do not show up in the default
Chris@394 367 file load filter. This is intentional, as there may be any kind of
Chris@394 368 data in them -- if you want to load uncompressed session files from
Chris@394 369 XML, you need to know you're doing it.
Chris@394 370
Chris@394 371 - Several crashes and other bugs have been fixed.
Chris@394 372
Chris@675 373
Chris@394 374 Changes in Sonic Visualiser 1.3 since the previous version 1.2:
Chris@394 375
Chris@394 376 - There is a new spreadsheet-style data viewer and editor for
Chris@394 377 viewing and editing the data in some types of annotation layer.
Chris@394 378
Chris@394 379 - Alignments are now saved to the session file.
Chris@394 380
Chris@394 381 - The spectrogram layer is usually somewhat faster than it was.
Chris@394 382
Chris@394 383 - You can now hold Shift while dragging to move an item, in order
Chris@394 384 to override the initial drag resistance introduced in 1.2.
Chris@394 385
Chris@394 386 - The gross mis-labelling of time lines in the ruler has been fixed.
Chris@394 387
Chris@394 388 - There is a new, somewhat provisional PulseAudio output driver.
Chris@394 389
Chris@394 390 - Several other bug fixes.
Chris@394 391
Chris@675 392
Chris@394 393 New features in Sonic Visualiser 1.2, since the previous version 1.0:
Chris@394 394
Chris@394 395 - SV now supports time-alignment of multiple performances of a work
Chris@394 396 loaded at the same time. This option is enabled when the MATCH Vamp
Chris@394 397 plugin is installed. When alignment is switched on and more than one
Chris@394 398 audio file is open, SV will assume that all open files are
Chris@394 399 differently timed performances of the same work, and will calculate
Chris@394 400 time alignments for them. Playback will then play only a single file
Chris@394 401 at a time, and the playback cursors in other files will track at the
Chris@394 402 varying speeds to try to ensure that each is at the same point in the
Chris@394 403 underlying score. This enables effective comparison of several such
Chris@394 404 files, as well as a meaningful way to switch from one performance to
Chris@394 405 another during playback (ensuring that the switch happens at the
Chris@394 406 correct point in the performance being switched to).
Chris@394 407
Chris@394 408 - There is a new Image layer, which can display images from the
Chris@394 409 local filesystem or retrieved via HTTP or FTP.
Chris@394 410
Chris@394 411 - A new measurement tool has been added. With the measurement tool
Chris@394 412 selected, dragging in a pane draws a rectangle labelled with the
Chris@394 413 scale values for its start and end corners and its size. You can
Chris@394 414 have any number of measurements present at once; they are associated
Chris@394 415 with the top layer, their scale values depend on the scale for that
Chris@394 416 layer, and they are only shown when that layer is at the top and the
Chris@394 417 measurement tool is active. Measurements are saved and reloaded in
Chris@394 418 the session file. Drawing measurements can be undone and redone, and
Chris@394 419 a measurement can be deleted by hitting Del when highlighted. Note
Chris@394 420 that the measurement tool shows the scale values associated with the
Chris@394 421 pixel positions of the mouse when dragging, not any values associated
Chris@394 422 with actual features present in the audio or its analysis (e.g. the
Chris@394 423 values are not rounded to the nearest spectrogram bin).
Chris@394 424
Chris@394 425 - You can double-click using the measurement tool in the spectrogram
Chris@394 426 to get an instant measurement rectangle for a feature. This is a
Chris@394 427 purely graphical feature that works by calculating the boundary of a
Chris@394 428 contiguous region of pixels "similar to" the one you double-clicked
Chris@394 429 on; it does not use audio analysis. Adjusting the gain and colour
Chris@394 430 scheme etc of the spectrogram will (by design) affect the
Chris@394 431 measurements obtained this way.
Chris@394 432
Chris@394 433 - The spectrum can now optionally show frequency estimates of peaks
Chris@394 434 aligned with a piano keyboard along the horizontal axis (this needs
Chris@394 435 some refinement).
Chris@394 436
Chris@394 437 - The harmonic cursor in the spectrogram has moved from the Select
Chris@394 438 tool to the Measurement tool. There is now a similar harmonic cursor
Chris@394 439 in the spectrum. Both of them show more information as text
Chris@394 440 alongside the cursor than previously.
Chris@394 441
Chris@394 442 - There is a new Erase tool for erasing individual points from an
Chris@394 443 editable layer.
Chris@394 444
Chris@394 445 - Several keyboard shortcuts have changed -- all of the Alt+key
Chris@394 446 shortcuts now either use Ctrl or a plain keypress with no modifier,
Chris@394 447 to avoid clashes with window manager shortcuts and to make them
Chris@394 448 easier to use and remember
Chris@394 449
Chris@394 450 - The playback controls are now in a Playback menu as well as the
Chris@394 451 toolbar.
Chris@394 452
Chris@394 453 - There is a new key and mouse control reference under Help (or press
Chris@394 454 F2).
Chris@394 455
Chris@394 456 - You can double-click on a pane in navigate mode to jump to a time.
Chris@394 457
Chris@394 458 - All of the single-colour layers (waveform, time values etc) now
Chris@394 459 allow you to define your own colours as well as using the built-in
Chris@394 460 set. The colour of a layer is now shown next to its name on the pane.
Chris@394 461
Chris@394 462 - When you add a new single-colour layer it will use a default colour
Chris@394 463 that is not yet in use in another layer (if there is one).
Chris@394 464
Chris@394 465 - Single-colour layers can now optionally have black backgrounds (with
Chris@394 466 a set of lighter colours in the default colour palette that use black
Chris@394 467 backgrounds by default).
Chris@394 468
Chris@394 469 - There's a new Printer colour scheme in the spectrogram with only a
Chris@394 470 small number of grey shades.
Chris@394 471
Chris@394 472 - Vertical zoom in a log-scaled spectrogram is much more intuitive;
Chris@394 473 it now leaves the point that was in the centre of the visible area in
Chris@394 474 the centre after zoom, instead of the point that was in the centre of
Chris@394 475 the linear range corresponding to the visible area.
Chris@394 476
Chris@394 477 - You can now turn a colour 3d plot layer upside down by clicking the
Chris@394 478 Invert Vertical Scale button.
Chris@394 479
Chris@394 480 - There's a new Layer Summary window which shows the panes and
Chris@394 481 layer data in a tree layout. This is very simplistic at the moment.
Chris@394 482
Chris@394 483 - Each pane now has an [X] button at its top left, which removes that
Chris@394 484 pane when clicked.
Chris@394 485
Chris@394 486 - There's a new Solo play mode toggle button; when active, only the
Chris@394 487 currently selected pane is played. This is also the default when
Chris@394 488 time alignment is in use.
Chris@394 489
Chris@394 490 - Rewind/ffwd now stay confined to the selection if Play Selection is
Chris@394 491 enabled; also, the rewind and ffwd "one step" buttons are now enabled
Chris@394 492 even if there is no time instants layer for them to align to (they
Chris@394 493 align to the time ruler instead and so jump in steps of a size
Chris@394 494 dependent on the zoom level).
Chris@394 495
Chris@394 496 - You can now export note layers to MIDI.
Chris@394 497
Chris@394 498 - MIDI note velocity is partially supported. Note velocity is
Chris@394 499 retained when importing and exporting MIDI and is used in playback,
Chris@394 500 but it is not yet shown in the display and cannot yet be edited.
Chris@394 501
Chris@394 502 - You can now drag-and-drop files (of whatever type) onto SV from
Chris@394 503 other programs such as file managers or web browsers.
Chris@394 504
Chris@394 505 - mp3 files (and Ogg, but they aren't supported on Windows at the
Chris@394 506 moment) are now decoded in a background thread so you can see the
Chris@394 507 start of the track without waiting for the rest to decode.
Chris@394 508
Chris@394 509 - Mac builds of SV can now load AAC/mp4 files and anything else
Chris@394 510 supported by QuickTime.
Chris@394 511
Chris@394 512 - There is now an option to resample audio files on import if they
Chris@394 513 don't match the samplerate of the first file loaded. By default this
Chris@394 514 is switched off, as it affects the visible waveform. The default
Chris@394 515 behaviour is unchanged (play at the wrong rate). There is still no
Chris@394 516 option to handle multiple rates "correctly" (i.e. by resampling
Chris@394 517 on playback and showing the waveforms at different resolutions
Chris@394 518 according to each one's underlying rate) and there probably never
Chris@394 519 will be.
Chris@394 520
Chris@394 521 - SV can now open .m3u playlist files, though it's a hazardous thing
Chris@394 522 to do as it simply loads all the files in the playlist at once.
Chris@394 523
Chris@394 524 - SV now has various options for how to number tapped time instants
Chris@394 525 (bar/beat, plain counter, time in seconds, tempo etc).
Chris@394 526
Chris@394 527 - The official builds use Qt 4.3, which fixes some nasty
Chris@394 528 bugs in the file dialog that the version 1.0 builds suffered from.
