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