Chris@2002 1
Chris@2002 2 Changes in Sonic Visualiser 3.2 since the previous release 3.1.1:
Chris@2002 3
Chris@2048 4 - Add ability to zoom closer than one sample per pixel, so as to see
Chris@2048 5 the interpolated signal level between samples
Chris@2048 6
Chris@2002 7 - Add feature to convert and import audio from a CSV data file
Chris@2002 8
Chris@2048 9 - Add some new colour maps, and restore the old Blue on Black one
Chris@2048 10
Chris@2048 11 - Fix failure to pass Nyquist bins correctly to
Chris@2048 12 frequency-domain-input Vamp plugins in some circumstances
Chris@2048 13
cannam@1948 14
cannam@1948 15 Changes in Sonic Visualiser 3.1.1 (Aug 2018) since the previous release 3.1:
cannam@1948 16
cannam@1948 17 - Fix failure to record correctly into an empty session with certain
cannam@1948 18 audio drivers
cannam@1948 19
Chris@1958 20 - Fix failure to run LADSPA plugins at all, except with some unusual
Chris@1958 21 path layouts
Chris@1958 22
Chris@1958 23 - Fix failure to silence sonified notes when rewinding backwards or
Chris@1958 24 jumping back from a loop endpoint
Chris@1958 25
cannam@1948 26 - Fix macOS .dmg image so as to use older HFS+ filesystem for compatibility
cannam@1948 27
Chris@1871 28
Chris@1932 29 Changes in Sonic Visualiser 3.1 (July 2018) since the previous release 3.0.3:
Chris@1871 30
Chris@1871 31 - Add Plugins tab to Preferences dialog, from which you can review
Chris@1871 32 the plugin load paths and see which plugins were loaded from which
Chris@1871 33 locations, and also customise load paths (though the various path
Chris@1871 34 environment variables are still supported)
Chris@1871 35
Chris@1935 36 - Stream the export of audio data and other CSV data so that
Chris@1935 37 very large exports don't hang the UI or run us out of memory
Chris@1935 38 (thanks to Lucas Thompson)
Chris@1935 39
Chris@1935 40 - Ensure vertical scale appears for auto-align layers when there is
Chris@1935 41 nothing else to auto-align them to
Chris@1935 42
Chris@1871 43 - Fix another long-standing Windows-platform wide-char/utf8
Chris@1871 44 conversion problem, with environment variable naming and contents
Chris@1871 45
Chris@1871 46 - Improve handling of incomplete session loads, i.e. situations where
Chris@1871 47 the audio files referred to by a session could not be found -
Chris@1871 48 previously the session could be re-saved immediately thus losing
Chris@1871 49 the audio reference; now at least we disable Save (enabling only
Chris@1871 50 Save As) and show a warning
Chris@1871 51
Chris@1871 52 - Update pane and layer menu shortcuts so that the
Chris@1871 53 waveform/spectrogram/etc shortcuts (Shift+G etc) operate on the
Chris@1871 54 source model in the currently-selected pane rather than the main
Chris@1871 55 model. This is a backward-incompatible change but is a far more
Chris@1871 56 intuitive way for the function to work
Chris@1871 57
Chris@1935 58 - Use dark background for bright colours in time-value/note/etc
Chris@1935 59 layers as well as e.g. waveforms - this is how it was always
Chris@1935 60 "intended to" work, but it is a backward-incompatible change
Chris@1935 61
Chris@1871 62 - Make "Select All" select the whole span of everything that exists,
Chris@1871 63 not just the main model
Chris@1871 64
Chris@1871 65 - Add horizontal scale to Spectrum layer
Chris@1871 66
Chris@1871 67 - Improve spacing and labelling of vertical log scales
Chris@1871 68
Chris@1871 69 - Update build system for better Cap'n Proto version support and to
Chris@1871 70 use Repoint for code management in the repository
Chris@1871 71
Chris@1871 72 - Various other bug fixes
Chris@1871 73
Chris@1702 74
Chris@1702 75 Changes in Sonic Visualiser 3.0.3 (May 2017) since the previous release 3.0.2:
Chris@1702 76
Chris@1702 77 - Improve decisions about where and how to label vertical scales
Chris@1702 78
Chris@1702 79 - Update build support material and documentation to reflect the
Chris@1702 80 official release of Cap'n Proto 0.6 (which we can now use rather
Chris@1702 81 than depending on git builds)
Chris@1702 82
Chris@1669 83
Chris@1669 84 Changes in Sonic Visualiser 3.0.2 (Mar 2017) since the previous release 3.0.1:
Chris@1669 85
Chris@1669 86 - Fix crash when changing parameters for spectrum view
Chris@1669 87
Chris@1669 88 - Fix incorrect measure tool crosshairs in spectrum view
Chris@1669 89
Chris@1669 90 - Update Russian and Czech UI translations (thanks to Alexandre Prokoudine
Chris@1669 91 and Pavel Fric respectively)
Chris@1702 92
Chris@1658 93
Chris@1658 94 Changes in Sonic Visualiser 3.0.1 (Mar 2017) since the previous release 3.0:
Chris@1658 95
Chris@1658 96 - Fix crashes with MIDI devices and speedup/slowdown control on Windows
Chris@1661 97
Chris@1658 98 - Update MIDI input driver layer
Chris@1447 99
Chris@1661 100
Chris@1624 101 Changes in Sonic Visualiser 3.0 (Mar 2017) since the previous release 2.5:
Chris@1447 102
Chris@1516 103 - Add ability to record audio, and ability to change the audio device
Chris@1516 104 for playback or recording in the preferences
Chris@1447 105
Chris@1447 106 - Add complete support for high-resolution (Hi-DPI or retina)
Chris@1511 107 displays, including for layer data rendering as well as UI controls
Chris@1511 108 and icons. This makes the biggest difference when using a retina
Chris@1511 109 Mac, on which previous versions did not render layer data at retina
Chris@1447 110 resolution, but it also improves scaling and rendering of UI
Chris@1447 111 elements on Hi-DPI displays on Windows and Linux
Chris@1447 112
Chris@1451 113 - Add ability to export scalable (SVG) image files
Chris@1451 114
Chris@1447 115 - Run plugins in a separate process, so that if a plugin crashes, it
Chris@1447 116 no longer brings down Sonic Visualiser with it. In every other
Chris@1447 117 respect the behaviour should be unchanged
Chris@1447 118
Chris@1447 119 - Scan plugins on startup in a separate process, and report on any
Chris@1447 120 that crash or won't load
Chris@1447 121
Chris@1527 122 - Add ability to open, display, and analyse very long audio files (of
Chris@1527 123 more than 2^32 sample frames)
Chris@1527 124
Chris@1447 125 - Change mp3 file loading so as to compensate for encoder/decoder
Chris@1447 126 delay and padding (using "gapless playback" logic). While this is a
Chris@1447 127 real improvement, unfortunately it does mean that the initial
Chris@1447 128 padding in mp3 file load has changed from previous versions, which
Chris@1447 129 may mean some sessions saved in previous versions are no longer
Chris@1447 130 correctly aligned. It's not a great idea to use mp3 as a file
Chris@1447 131 format of record, because of differences like this between
Chris@1447 132 decoders. The previous behaviour is still available as a preference.
Chris@1447 133
Chris@1470 134 - Add new Hybrid normalisation type for spectrogram and colour 3d
Chris@1470 135 plot layers. This normalises each column to its peak value and then
Chris@1470 136 scales the normalised values by the log of the peak in order to
Chris@1470 137 restore some distinction in scale between columns with different
Chris@1470 138 levels. It can provide quite visually clear results.
Chris@1470 139
Chris@1447 140 - Add function to subdivide time instant layers into regular
Chris@1447 141 intervals (and its inverse)
Chris@1447 142
Chris@1447 143 - Add new preference for default colour scales
Chris@1447 144
Chris@1578 145 - Add a basic ability to zoom (in the frequency axis) to the spectrum
Chris@1624 146
Chris@1447 147 - Switch to using combined level/pan controls in layer property boxes
Chris@1447 148 and for the main volume control
Chris@1447 149
Chris@1520 150 - Make CSV file reader better able to handle files with varying
Chris@1520 151 numbers of columns
Chris@1520 152
Chris@1516 153 - Fix a number of problems on Windows with loading and saving some
Chris@1516 154 file formats to filenames not representable in system codepage
Chris@1516 155
Chris@1520 156 - Add "What's New" dialog
Chris@1520 157
Chris@1527 158 - Finally switch the Windows build to 64-bit by default (with
Chris@1447 159 adapters to run either 32- or 64-bit plugins)
Chris@1451 160
Chris@1447 161
Chris@1520 162 Changes in Sonic Visualiser 2.5 (Oct 2015) since the previous release 2.4.1:
Chris@1072 163
Chris@1072 164 - Add unit-converter dialog, for converting between various pitch and
Chris@1072 165 timing units
Chris@1072 166
Chris@1072 167 - Fix failure to reload note layers from session file
Chris@1072 168
Chris@1072 169 - Use a more sensible scale for the play-speed dial
Chris@1072 170
Chris@1072 171 - Fix crash when importing very wide CSV files
Chris@1072 172
Chris@1072 173 - Fix generation of wrong layer type from some CSV files
Chris@1072 174
Chris@1072 175 - Fix failure to export last instant in a time-instant layer
Chris@1072 176
Chris@1457 177
Chris@1520 178 Changes in Sonic Visualiser 2.4.1 (Oct 2014) since the previous release 2.4:
Chris@876 179
Chris@876 180 - Fix a crash when rendering certain colour 3d plot layers
Chris@716 181
Chris@1457 182
Chris@1520 183 Changes in Sonic Visualiser 2.4 (Sep 2014) since the previous release 2.3:
Chris@714 184
Chris@776 185 - Add support for left/right scrolling using a two-finger touchpad
Chris@776 186 gesture (where available)
Chris@776 187
Chris@716 188 - Make the octave numbering into a configurable option, and change
Chris@716 189 the default. Previously Sonic Visualiser labelled middle-C as "C3";
Chris@716 190 now it labels middle-C as "C4", a more common standard in the world
Chris@776 191 outside MIDI sequencer software. The previous system is available
Chris@776 192 as an option in the Preferences. This affects only the visible
Chris@776 193 labels: there is no change to analysis or to the file format
Chris@714 194
Chris@714 195 - Sonify time-value layers. Any time-value curve whose scale unit is
Chris@714 196 set to Hz will now acquire a playback toggle control; this control
Chris@714 197 is off by default, but if it is switched on, the curve will be
Chris@714 198 played back using a variable-frequency sound generator
Chris@714 199
Chris@714 200 - Add support for playback of note layers with non-MIDI frequencies
Chris@714 201 (formerly the note playback was limited to exact MIDI pitch)
Chris@714 202
Chris@714 203 - Change the default playback sample for note layers from piano to an
Chris@714 204 electric piano with sustain. The piano sample is still available,
Chris@714 205 and any sessions saved using it should continue to use it
Chris@714 206
Chris@867 207 - Add a cancel button for Vamp plugin processing: currently,
Chris@867 208 cancelling a transform results in a part-complete layer rather than
Chris@867 209 removing the results
Chris@867 210
Chris@790 211 - Add keyboard shortcuts to cycle the current layer (in addition to
Chris@790 212 the existing ones to cycle the current pane)
Chris@790 213
Chris@790 214 - Fix various bugs related to layer ordering: layer tabs re-ordering
Chris@790 215 themselves randomly when new layer added, layers being ordered
Chris@791 216 randomly when saving and reloading a session
Chris@790 217
Chris@848 218 - Fix incorrect interaction with non-Unicode usernames when creating
Chris@848 219 temporary and template directories on Windows
Chris@848 220
Chris@714 221 - Shade the start and end of the main audio file, to make them easier
Chris@714 222 to see for files that start or end in silence
Chris@714 223
Chris@714 224 - Speed up rendering and scrolling in time-value layers
Chris@714 225
Chris@714 226 - Make it possible to import CSV files directly into Note layers by
Chris@714 227 adding Pitch as a data type in the CSV file import dialog
Chris@675 228
Chris@856 229 - Fix play pointer jump to wrong frame when clicking on row in the
Chris@856 230 layer edit dialog
Chris@856 231
Chris@848 232 - Fix problems with keyboard shortcuts when using Qt5 on OS/X. This
Chris@848 233 is the first release in which the official builds use Qt5 for all
Chris@848 234 platforms.
Chris@848 235
Chris@675 236
Chris@1520 237 Changes in Sonic Visualiser 2.3 (Dec 2013) since the previous release 2.2:
Chris@675 238
Chris@675 239 - Add a startup welcome dialog that also explains what SV makes
Chris@675 240 network connections for and allows user to forbid them
Chris@675 241
Chris@675 242 - Add "Export Audio Data" feature
Chris@675 243
Chris@675 244 - Show piano keyboard scale in note and time-value layers as well
Chris@675 245 as spectrogram, where vertical scale is log Hz; also show
Chris@675 246 numerical scale in note and region layers when not auto-aligned
Chris@675 247
Chris@675 248 - Speed up CSV file import and avoid showing crazily wide window
Chris@675 249 for CSV file format dialog when file has lots of columns
Chris@675 250
Chris@675 251 - Fix incorrectly saved window geometry when exiting from maximised
Chris@675 252 state
Chris@675 253
Chris@675 254 - Reduce number of timer wakeups when idle
Chris@675 255
Chris@675 256 - Add American English translation and make choice of translation
Chris@675 257 into a preference (defaulting to system locale)
Chris@675 258
Chris@675 259 - Permit installation to non-default location with Windows installer
Chris@675 260 build
Chris@714 261
Chris@608 262
Chris@1520 263 Changes in Sonic Visualiser 2.2 (July 2013) since the previous release 2.1:
Chris@608 264
Chris@608 265 - Build with support for hidpi ("retina") text on OS/X
Chris@675 266
Chris@608 267 - Fix very slow analysis when using Ogg or FLAC files decoded
Chris@608 268 via libsndfile
Chris@675 269
Chris@608 270 - Fix inaccurate scale auto-align between time-value layers and
Chris@608 271 others
Chris@675 272
Chris@608 273 - Fix failure to open files specified on command line (or via
Chris@608 274 Open With) on Windows
Chris@675 275
Chris@608 276 - Reset cyclical counters and switch back to navigate mode when
Chris@608 277 a new session is started
Chris@579 278
Chris@675 279
Chris@1520 280 Changes in Sonic Visualiser 2.1 (May 2013) since the previous release 2.0.1:
Chris@579 281
Chris@579 282 - Fix incorrect handling of FixedSampleRate outputs (Vamp SDK fix)
Chris@675 283
Chris@579 284 - Make it easier to see results from transforms that return a single point
Chris@675 285
Chris@579 286 - Make labelling clearer on time-value layers
Chris@675 287
Chris@579 288 - Add discrete-curve mode for time-value layers (for curves with gaps)
Chris@675 289
Chris@579 290 - Update code to build against Qt5
Chris@523 291
Chris@675 292
Chris@523 293 Changes in Sonic Visualiser 2.0.1 since the previous release 2.0:
Chris@523 294
Chris@523 295 - Fix incorrect samplerate in reading m4a files on OS/X
Chris@512 296
Chris@675 297
Chris@1520 298 Changes in Sonic Visualiser 2.0 (July 2012) since the previous release 1.9:
Chris@512 299
Chris@512 300 - Support 64-bit builds on OS/X (using CoreAudio instead of
Chris@512 301 obsolete QuickTime audio file reader)
Chris@512 302
Chris@512 303 - Simplify RDF reading and fix some bugs. Now requires Dataquay
Chris@512 304 (http://breakfastquay.com/dataquay/) rather than using Redland
Chris@512 305 directly. Release builds use Sord/Serd rather than Redland
Chris@512 306
Chris@512 307 - Add a fullscreen mode on the F11 key
Chris@471 308
Chris@675 309
Chris@1520 310 Changes in Sonic Visualiser 1.9 (Oct 2011) since the previous release 1.8:
Chris@471 311
Chris@471 312 - Add session templates; save session as template; apply template to
Chris@471 313 session
Chris@471 314
Chris@471 315 - Tidy up the file open logic so as to remove the dialog asking how
Chris@471 316 to open a file, where possible
Chris@471 317
Chris@471 318 - Various bug fixes.
Chris@394 319
Chris@675 320
Chris@1520 321 Changes in Sonic Visualiser 1.8 (Apr 2011) since the previous release 1.7.2:
Chris@394 322
Chris@394 323 - Sonic Visualiser now registers as a file type handler on OS/X,
Chris@394 324 providing better integration with the desktop generally (Dan Stowell)
Chris@394 325
Chris@394 326 - There is a new function to toggle all Time Rulers at once (key #)
Chris@394 327
Chris@407 328 - The CSV import dialog has been overhauled, allowing more flexible
Chris@407 329 selection of purpose for each column
Chris@407 330
Chris@394 331 - Text overlays are now easier to read on dark backgrounds
Chris@394 332
Chris@394 333 - Hidden layers are now ignored when exporting an image (Dan Stowell)
Chris@394 334
Chris@394 335 - A crash when starting a new session or exiting the application
Chris@394 336 after loading a session with saved alignment data has been fixed
Chris@394 337
Chris@394 338 - The duplication of right-button menu functions when multiple files
Chris@394 339 were loaded has been fixed
Chris@394 340
Chris@394 341 - The layer-add menu functions now have shortcuts (Dan Stowell)
Chris@394 342
Chris@394 343 - The codebase has been reorganised into libraries and a configure
Chris@394 344 step added. It should be easier to build and maintain on OS/X and
Chris@394 345 Linux than previously, although it won't make much difference on
Chris@394 346 Windows.
Chris@394 347
Chris@397 348 - A Czech translation is now included (thanks to Pavel Fric).
Chris@397 349
Chris@675 350
Chris@1520 351 Changes in Sonic Visualiser 1.7.2 (May 2010) since the previous release 1.7.1:
Chris@394 352
Chris@394 353 - The time-value layer now has an origin line and an option to
Chris@394 354 show derivatives (change from one point to the next) rather than
Chris@394 355 raw values
Chris@394 356
Chris@394 357 - A static initialiser race has been fixed, possibly fixing an
Chris@394 358 occasional crash on startup in Windows
Chris@394 359
Chris@394 360 - A crash when pressing Play straight after New Session has been
Chris@394 361 fixed
Chris@394 362
Chris@675 363
Chris@1520 364 Changes in Sonic Visualiser 1.7.1 (Oct 2009) since the previous release 1.7:
Chris@394 365
Chris@394 366 - The RDF importer does a better job of assigning labels to layers,
Chris@394 367 layers to panes, and values to labelled regions
Chris@394 368
Chris@394 369 - Interactive editing in the Text layer benefits from the same
Chris@394 370 improvements as made in 1.7 to Note and Region layers
Chris@394 371
Chris@394 372 - The layer data editor window has a text search feature
Chris@394 373
Chris@394 374 - The main window status bar now shows the last label to have passed
Chris@394 375 the playback position in the current layer, at the right end of the
Chris@394 376 status bar
Chris@394 377
Chris@394 378 - The Russian translation has been updated (thanks Alexandre)
Chris@394 379
Chris@675 380
Chris@1520 381 Changes in Sonic Visualiser 1.7 (Sep 2009) since the previous release 1.6:
Chris@394 382
Chris@394 383 - A new "Insert Item At Selection" function on the Edit menu
Chris@394 384 can be used to create Note and Region layer items whose time
Chris@394 385 extents correspond to the current selection(s)
Chris@394 386
Chris@394 387 - Interactively editing points in the Note and Region layers
Chris@394 388 now works much more smoothly
Chris@394 389
Chris@394 390 - SV can now import MIDI files that use SMPTE timecode for event
Chris@394 391 timing (importing MIDI files using with the more common
Chris@394 392 timebase-based timing was already supported)
Chris@394 393
Chris@394 394 - Time values throughout the display may optionally be shown in
Chris@394 395 seconds and frames at various frame rates
Chris@1520 396
Chris@394 397 - A crash on exit in Windows has been fixed
Chris@394 398
Chris@394 399 - A very unobtrusive user survey is now included
Chris@394 400
Chris@394 401 - Various other bug fixes.
Chris@394 402
Chris@675 403
Chris@1520 404 Changes in Sonic Visualiser 1.6 (Jun 2009) since the previous release 1.5:
Chris@394 405
Chris@394 406 - The Colour 3D Plot layer now supports logarithmic vertical
Chris@394 407 scale and linear interpolation options.
Chris@394 408
Chris@394 409 - A new colour scheme (High Gain) has been added for spectrogram
Chris@394 410 and Colour 3D Plot, which improves readability for some data.
Chris@394 411
Chris@394 412 - Further performance improvements have been made to Colour 3D
Chris@394 413 Plot.
Chris@394 414
Chris@394 415 - Various other bug fixes.
Chris@394 416
Chris@675 417
Chris@1520 418 Changes in Sonic Visualiser 1.5 (Mar 2009) since the previous release 1.4:
Chris@394 419
Chris@394 420 - You can now insert time instants, time values, and notes using
Chris@394 421 a MIDI device during playback. If a time value or note layer is
Chris@394 422 current it will be used for insertion (giving a value equal to
Chris@394 423 the pitch class, or the played note, respectively); otherwise an
Chris@394 424 existing or new time instants layer will be used just as it is
Chris@394 425 when inserting instants using the PC keyboard. Using a MIDI
Chris@394 426 device should give better timing than using the PC keyboard.
Chris@394 427
Chris@394 428 - There is a new Activity Log window with a (purely informative) list
Chris@394 429 of events and user interactions that happen while SV is running.
Chris@394 430
Chris@394 431 - The spectrogram has somewhat improved graphical scaling, and
Chris@394 432 this is now the default (being much faster than the 4x oversampled
Chris@394 433 method). The previous default is still available as a preference.
Chris@394 434
Chris@394 435 - Visualisation of very dense colour plots (such as spectrograms
Chris@394 436 calculated by plugins) is substantially faster in this release.
Chris@394 437
Chris@394 438 - Spectrogram display is now faster in many circumstances.
Chris@394 439
Chris@394 440 - Alignment using the MATCH plugin is faster on OS/X than before.
Chris@394 441
Chris@394 442 - SV will take into account RDF plugin descriptions, if available,
Chris@394 443 in order to make somewhat better decisions about display of plugin
Chris@394 444 outputs (for example, placing segmentation data into a layer with
Chris@394 445 segmentation plot type).
Chris@394 446
Chris@394 447 - You can now switch layers by clicking on the spare area at the left
Chris@394 448 end of the pane that is also used for the current pane indicator.
Chris@394 449
Chris@394 450 - The vertical black lines dividing segments in the time value
Chris@394 451 layer's segmentation plot style are now optional.
Chris@394 452
Chris@394 453 - Several widget layout bugs on OS/X have been fixed.
Chris@394 454
Chris@394 455 - Several serious crashing, deadlock, and data corruption bugs have
Chris@394 456 been fixed.
Chris@394 457
Chris@394 458
Chris@1520 459 Changes in Sonic Visualiser 1.4 (Dec 2008) since the previous release 1.3:
Chris@394 460
Chris@394 461 - SV now has a Region layer type, used for display of features with
Chris@394 462 durations. It also supports Vamp v2.0 plugins that provide durations
Chris@394 463 for features.
Chris@394 464
Chris@394 465 - Layer data can now be imported from RDF described using the Audio
Chris@394 466 Features Ontology, as well as from the existing text file types. SV
Chris@394 467 can also export annotation layer data to RDF/Turtle, although in a
Chris@394 468 somewhat simplistic manner at present.
Chris@394 469
Chris@394 470 - You can search for transforms by text in the new "Find a Transform"
Chris@394 471 dialog. This searches both installed plugins, and plugins that have
Chris@394 472 not been installed but that have descriptions available on the
Chris@394 473 semantic web.
Chris@394 474
Chris@394 475 - You can now zoom and scroll vertically in the time-value, note,
Chris@394 476 and colour 3d plot layers.
Chris@394 477
Chris@394 478 - Sonic Visualiser can now load sessions from uncompressed XML files
Chris@394 479 as well as its own compressed-XML .sv format. Files with extension
Chris@394 480 .xml that contain suitable session data will be loaded as sessions.
Chris@394 481 Note that .xml extension files still do not show up in the default
Chris@394 482 file load filter. This is intentional, as there may be any kind of
Chris@394 483 data in them -- if you want to load uncompressed session files from
Chris@394 484 XML, you need to know you're doing it.
Chris@394 485
Chris@394 486 - Several crashes and other bugs have been fixed.
Chris@394 487
Chris@675 488
Chris@1520 489 Changes in Sonic Visualiser 1.3 (Jul 2008) since the previous release 1.2:
Chris@394 490
Chris@394 491 - There is a new spreadsheet-style data viewer and editor for
Chris@394 492 viewing and editing the data in some types of annotation layer.
Chris@394 493
Chris@394 494 - Alignments are now saved to the session file.
Chris@394 495
Chris@394 496 - The spectrogram layer is usually somewhat faster than it was.
Chris@394 497
Chris@394 498 - You can now hold Shift while dragging to move an item, in order
Chris@394 499 to override the initial drag resistance introduced in 1.2.
Chris@394 500
Chris@394 501 - The gross mis-labelling of time lines in the ruler has been fixed.
Chris@394 502
Chris@394 503 - There is a new, somewhat provisional PulseAudio output driver.
Chris@394 504
Chris@394 505 - Several other bug fixes.
Chris@394 506
Chris@675 507
Chris@1520 508 Changes in Sonic Visualiser 1.2 (Feb 2008) since the previous release 1.0:
Chris@394 509
Chris@394 510 - SV now supports time-alignment of multiple performances of a work
Chris@394 511 loaded at the same time. This option is enabled when the MATCH Vamp
Chris@394 512 plugin is installed. When alignment is switched on and more than one
Chris@394 513 audio file is open, SV will assume that all open files are
Chris@394 514 differently timed performances of the same work, and will calculate
Chris@394 515 time alignments for them. Playback will then play only a single file
Chris@394 516 at a time, and the playback cursors in other files will track at the
Chris@394 517 varying speeds to try to ensure that each is at the same point in the
Chris@394 518 underlying score. This enables effective comparison of several such
Chris@394 519 files, as well as a meaningful way to switch from one performance to
Chris@394 520 another during playback (ensuring that the switch happens at the
Chris@394 521 correct point in the performance being switched to).
Chris@394 522
Chris@394 523 - There is a new Image layer, which can display images from the
Chris@394 524 local filesystem or retrieved via HTTP or FTP.
Chris@394 525
Chris@394 526 - A new measurement tool has been added. With the measurement tool
Chris@394 527 selected, dragging in a pane draws a rectangle labelled with the
Chris@394 528 scale values for its start and end corners and its size. You can
Chris@394 529 have any number of measurements present at once; they are associated
Chris@394 530 with the top layer, their scale values depend on the scale for that
Chris@394 531 layer, and they are only shown when that layer is at the top and the
Chris@394 532 measurement tool is active. Measurements are saved and reloaded in
Chris@394 533 the session file. Drawing measurements can be undone and redone, and
Chris@394 534 a measurement can be deleted by hitting Del when highlighted. Note
Chris@394 535 that the measurement tool shows the scale values associated with the
Chris@394 536 pixel positions of the mouse when dragging, not any values associated
Chris@394 537 with actual features present in the audio or its analysis (e.g. the
Chris@394 538 values are not rounded to the nearest spectrogram bin).
Chris@394 539
Chris@394 540 - You can double-click using the measurement tool in the spectrogram
Chris@394 541 to get an instant measurement rectangle for a feature. This is a
Chris@394 542 purely graphical feature that works by calculating the boundary of a
Chris@394 543 contiguous region of pixels "similar to" the one you double-clicked
Chris@394 544 on; it does not use audio analysis. Adjusting the gain and colour
Chris@394 545 scheme etc of the spectrogram will (by design) affect the
Chris@394 546 measurements obtained this way.
Chris@394 547
Chris@394 548 - The spectrum can now optionally show frequency estimates of peaks
Chris@394 549 aligned with a piano keyboard along the horizontal axis (this needs
Chris@394 550 some refinement).
Chris@394 551
Chris@394 552 - The harmonic cursor in the spectrogram has moved from the Select
Chris@394 553 tool to the Measurement tool. There is now a similar harmonic cursor
Chris@394 554 in the spectrum. Both of them show more information as text
Chris@394 555 alongside the cursor than previously.
Chris@394 556
Chris@394 557 - There is a new Erase tool for erasing individual points from an
Chris@394 558 editable layer.
Chris@394 559
Chris@394 560 - Several keyboard shortcuts have changed -- all of the Alt+key
Chris@394 561 shortcuts now either use Ctrl or a plain keypress with no modifier,
Chris@394 562 to avoid clashes with window manager shortcuts and to make them
Chris@394 563 easier to use and remember
Chris@394 564
Chris@394 565 - The playback controls are now in a Playback menu as well as the
Chris@394 566 toolbar.
Chris@394 567
Chris@394 568 - There is a new key and mouse control reference under Help (or press
Chris@394 569 F2).
Chris@394 570
Chris@394 571 - You can double-click on a pane in navigate mode to jump to a time.
Chris@394 572
Chris@394 573 - All of the single-colour layers (waveform, time values etc) now
Chris@394 574 allow you to define your own colours as well as using the built-in
Chris@394 575 set. The colour of a layer is now shown next to its name on the pane.
Chris@394 576
Chris@394 577 - When you add a new single-colour layer it will use a default colour
Chris@394 578 that is not yet in use in another layer (if there is one).
Chris@394 579
Chris@394 580 - Single-colour layers can now optionally have black backgrounds (with
Chris@394 581 a set of lighter colours in the default colour palette that use black
Chris@394 582 backgrounds by default).
Chris@394 583
Chris@394 584 - There's a new Printer colour scheme in the spectrogram with only a
Chris@394 585 small number of grey shades.
Chris@394 586
Chris@394 587 - Vertical zoom in a log-scaled spectrogram is much more intuitive;
Chris@394 588 it now leaves the point that was in the centre of the visible area in
Chris@394 589 the centre after zoom, instead of the point that was in the centre of
Chris@394 590 the linear range corresponding to the visible area.
Chris@394 591
Chris@394 592 - You can now turn a colour 3d plot layer upside down by clicking the
Chris@394 593 Invert Vertical Scale button.
Chris@394 594
Chris@394 595 - There's a new Layer Summary window which shows the panes and
Chris@394 596 layer data in a tree layout. This is very simplistic at the moment.
Chris@394 597
Chris@394 598 - Each pane now has an [X] button at its top left, which removes that
Chris@394 599 pane when clicked.
Chris@394 600
Chris@394 601 - There's a new Solo play mode toggle button; when active, only the
Chris@394 602 currently selected pane is played. This is also the default when
Chris@394 603 time alignment is in use.
Chris@394 604
Chris@394 605 - Rewind/ffwd now stay confined to the selection if Play Selection is
Chris@394 606 enabled; also, the rewind and ffwd "one step" buttons are now enabled
Chris@394 607 even if there is no time instants layer for them to align to (they
Chris@394 608 align to the time ruler instead and so jump in steps of a size
Chris@394 609 dependent on the zoom level).
Chris@394 610
Chris@394 611 - You can now export note layers to MIDI.
Chris@394 612
Chris@394 613 - MIDI note velocity is partially supported. Note velocity is
Chris@394 614 retained when importing and exporting MIDI and is used in playback,
Chris@394 615 but it is not yet shown in the display and cannot yet be edited.
Chris@394 616
Chris@394 617 - You can now drag-and-drop files (of whatever type) onto SV from
Chris@394 618 other programs such as file managers or web browsers.
Chris@394 619
Chris@394 620 - mp3 files (and Ogg, but they aren't supported on Windows at the
Chris@394 621 moment) are now decoded in a background thread so you can see the
Chris@394 622 start of the track without waiting for the rest to decode.
Chris@394 623
Chris@394 624 - Mac builds of SV can now load AAC/mp4 files and anything else
Chris@394 625 supported by QuickTime.
Chris@394 626
Chris@394 627 - There is now an option to resample audio files on import if they
Chris@394 628 don't match the samplerate of the first file loaded. By default this
Chris@394 629 is switched off, as it affects the visible waveform. The default
Chris@394 630 behaviour is unchanged (play at the wrong rate). There is still no
Chris@394 631 option to handle multiple rates "correctly" (i.e. by resampling
Chris@394 632 on playback and showing the waveforms at different resolutions
Chris@394 633 according to each one's underlying rate) and there probably never
Chris@394 634 will be.
Chris@394 635
Chris@394 636 - SV can now open .m3u playlist files, though it's a hazardous thing
Chris@394 637 to do as it simply loads all the files in the playlist at once.
Chris@394 638
Chris@394 639 - SV now has various options for how to number tapped time instants
Chris@394 640 (bar/beat, plain counter, time in seconds, tempo etc).
Chris@394 641
Chris@394 642 - The official builds use Qt 4.3, which fixes some nasty
Chris@394 643 bugs in the file dialog that the version 1.0 builds suffered from.
Chris@394 644
