Chris@2175 13
Chris@2175 14
Chris@2175 15 Changes in Sonic Visualiser 3.2 (Dec 2018) since the previous release 3.1.1:
Chris@2002 16
Chris@2048 17 - Add ability to zoom closer than one sample per pixel, so as to see
Chris@2048 18 the interpolated signal level between samples
Chris@2048 19
Chris@2110 20 - Add oversampling control to the spectrogram and spectrum layers
Chris@2110 21
Chris@2110 22 - Highlight and label frequency peaks in the spectrum as the mouse
Chris@2110 23 rolls over them, when enabled in the parameter area
Chris@2110 24
Chris@2002 25 - Add feature to convert and import audio from a CSV data file
Chris@2002 26
Chris@2048 27 - Add some new colour maps, and restore the old Blue on Black one
Chris@2048 28
Chris@2110 29 - Speed up spectrum rendering at high resolutions

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