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