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