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