Chris@394 1
Chris@394 2 Changes in Sonic Visualiser 1.8 since the previous release 1.7.2:
Chris@394 3
Chris@394 4 - Sonic Visualiser now registers as a file type handler on OS/X,
Chris@394 5 providing better integration with the desktop generally (Dan Stowell)
Chris@394 6
Chris@394 7 - There is a new function to toggle all Time Rulers at once (key #)
Chris@394 8
Chris@394 9 - Text overlays are now easier to read on dark backgrounds
Chris@394 10
Chris@394 11 - Hidden layers are now ignored when exporting an image (Dan Stowell)
Chris@394 12
Chris@394 13 - A crash when starting a new session or exiting the application
Chris@394 14 after loading a session with saved alignment data has been fixed
Chris@394 15
Chris@394 16 - The duplication of right-button menu functions when multiple files
Chris@394 17 were loaded has been fixed
Chris@394 18
Chris@394 19 - The layer-add menu functions now have shortcuts (Dan Stowell)
Chris@394 20
Chris@394 21 - The codebase has been reorganised into libraries and a configure
Chris@394 22 step added. It should be easier to build and maintain on OS/X and
Chris@394 23 Linux than previously, although it won't make much difference on
Chris@394 24 Windows.
Chris@394 25
Chris@394 26 Changes in Sonic Visualiser 1.7.2 since the previous release 1.7.1:
Chris@394 27
Chris@394 28 - The time-value layer now has an origin line and an option to
Chris@394 29 show derivatives (change from one point to the next) rather than
Chris@394 30 raw values
Chris@394 31
Chris@394 32 - A static initialiser race has been fixed, possibly fixing an
Chris@394 33 occasional crash on startup in Windows
Chris@394 34
Chris@394 35 - A crash when pressing Play straight after New Session has been
Chris@394 36 fixed
Chris@394 37
Chris@394 38 Changes in Sonic Visualiser 1.7.1 since the previous release 1.7:
Chris@394 39
Chris@394 40 - The RDF importer does a better job of assigning labels to layers,
Chris@394 41 layers to panes, and values to labelled regions
Chris@394 42
Chris@394 43 - Interactive editing in the Text layer benefits from the same
Chris@394 44 improvements as made in 1.7 to Note and Region layers
Chris@394 45
Chris@394 46 - The layer data editor window has a text search feature
Chris@394 47
Chris@394 48 - The main window status bar now shows the last label to have passed
Chris@394 49 the playback position in the current layer, at the right end of the
Chris@394 50 status bar
Chris@394 51
Chris@394 52 - The Russian translation has been updated (thanks Alexandre)
Chris@394 53
Chris@394 54 Changes in Sonic Visualiser 1.7 since the previous release 1.6:
Chris@394 55
Chris@394 56 - A new "Insert Item At Selection" function on the Edit menu
Chris@394 57 can be used to create Note and Region layer items whose time
Chris@394 58 extents correspond to the current selection(s)
Chris@394 59
Chris@394 60 - Interactively editing points in the Note and Region layers
Chris@394 61 now works much more smoothly
Chris@394 62
Chris@394 63 - SV can now import MIDI files that use SMPTE timecode for event
Chris@394 64 timing (importing MIDI files using with the more common
Chris@394 65 timebase-based timing was already supported)
Chris@394 66
Chris@394 67 - Time values throughout the display may optionally be shown in
Chris@394 68 seconds and frames at various frame rates
Chris@394 69
Chris@394 70 - A crash on exit in Windows has been fixed
Chris@394 71
Chris@394 72 - A very unobtrusive user survey is now included
Chris@394 73
Chris@394 74 - Various other bug fixes.
Chris@394 75
Chris@394 76 Changes in Sonic Visualiser 1.6 since the previous release 1.5:
Chris@394 77
Chris@394 78 - The Colour 3D Plot layer now supports logarithmic vertical
Chris@394 79 scale and linear interpolation options.
Chris@394 80
Chris@394 81 - A new colour scheme (High Gain) has been added for spectrogram
Chris@394 82 and Colour 3D Plot, which improves readability for some data.
Chris@394 83
Chris@394 84 - Further performance improvements have been made to Colour 3D
Chris@394 85 Plot.
Chris@394 86
Chris@394 87 - Various other bug fixes.
Chris@394 88
Chris@394 89 Changes in Sonic Visualiser 1.5 since the previous version 1.4:
Chris@394 90
Chris@394 91 - You can now insert time instants, time values, and notes using
Chris@394 92 a MIDI device during playback. If a time value or note layer is
Chris@394 93 current it will be used for insertion (giving a value equal to
Chris@394 94 the pitch class, or the played note, respectively); otherwise an
Chris@394 95 existing or new time instants layer will be used just as it is
Chris@394 96 when inserting instants using the PC keyboard. Using a MIDI
Chris@394 97 device should give better timing than using the PC keyboard.
Chris@394 98
Chris@394 99 - There is a new Activity Log window with a (purely informative) list
Chris@394 100 of events and user interactions that happen while SV is running.
Chris@394 101
Chris@394 102 - The spectrogram has somewhat improved graphical scaling, and
Chris@394 103 this is now the default (being much faster than the 4x oversampled
Chris@394 104 method). The previous default is still available as a preference.
Chris@394 105
Chris@394 106 - Visualisation of very dense colour plots (such as spectrograms
Chris@394 107 calculated by plugins) is substantially faster in this release.
Chris@394 108
Chris@394 109 - Spectrogram display is now faster in many circumstances.
Chris@394 110
Chris@394 111 - Alignment using the MATCH plugin is faster on OS/X than before.
Chris@394 112
Chris@394 113 - SV will take into account RDF plugin descriptions, if available,
Chris@394 114 in order to make somewhat better decisions about display of plugin
Chris@394 115 outputs (for example, placing segmentation data into a layer with
Chris@394 116 segmentation plot type).
Chris@394 117
Chris@394 118 - You can now switch layers by clicking on the spare area at the left
Chris@394 119 end of the pane that is also used for the current pane indicator.
Chris@394 120
Chris@394 121 - The vertical black lines dividing segments in the time value
Chris@394 122 layer's segmentation plot style are now optional.
Chris@394 123
Chris@394 124 - Several widget layout bugs on OS/X have been fixed.
Chris@394 125
Chris@394 126 - Several serious crashing, deadlock, and data corruption bugs have
Chris@394 127 been fixed.
Chris@394 128
Chris@394 129
Chris@394 130 New features in Sonic Visualiser 1.4 since the previous version 1.3:
Chris@394 131
Chris@394 132 - SV now has a Region layer type, used for display of features with
Chris@394 133 durations. It also supports Vamp v2.0 plugins that provide durations
Chris@394 134 for features.
Chris@394 135
Chris@394 136 - Layer data can now be imported from RDF described using the Audio
Chris@394 137 Features Ontology, as well as from the existing text file types. SV
Chris@394 138 can also export annotation layer data to RDF/Turtle, although in a
Chris@394 139 somewhat simplistic manner at present.
Chris@394 140
Chris@394 141 - You can search for transforms by text in the new "Find a Transform"
Chris@394 142 dialog. This searches both installed plugins, and plugins that have
Chris@394 143 not been installed but that have descriptions available on the
Chris@394 144 semantic web.
Chris@394 145
Chris@394 146 - You can now zoom and scroll vertically in the time-value, note,
Chris@394 147 and colour 3d plot layers.
Chris@394 148
Chris@394 149 - Sonic Visualiser can now load sessions from uncompressed XML files
Chris@394 150 as well as its own compressed-XML .sv format. Files with extension
Chris@394 151 .xml that contain suitable session data will be loaded as sessions.
Chris@394 152 Note that .xml extension files still do not show up in the default
Chris@394 153 file load filter. This is intentional, as there may be any kind of
Chris@394 154 data in them -- if you want to load uncompressed session files from
Chris@394 155 XML, you need to know you're doing it.
Chris@394 156
Chris@394 157 - Several crashes and other bugs have been fixed.
Chris@394 158
Chris@394 159 Changes in Sonic Visualiser 1.3 since the previous version 1.2:
Chris@394 160
Chris@394 161 - There is a new spreadsheet-style data viewer and editor for
Chris@394 162 viewing and editing the data in some types of annotation layer.
Chris@394 163
Chris@394 164 - Alignments are now saved to the session file.
Chris@394 165
Chris@394 166 - The spectrogram layer is usually somewhat faster than it was.
Chris@394 167
Chris@394 168 - You can now hold Shift while dragging to move an item, in order
Chris@394 169 to override the initial drag resistance introduced in 1.2.
Chris@394 170
Chris@394 171 - The gross mis-labelling of time lines in the ruler has been fixed.
Chris@394 172
Chris@394 173 - There is a new, somewhat provisional PulseAudio output driver.
Chris@394 174
Chris@394 175 - Several other bug fixes.
Chris@394 176
Chris@394 177 New features in Sonic Visualiser 1.2, since the previous version 1.0:
Chris@394 178
Chris@394 179 - SV now supports time-alignment of multiple performances of a work
Chris@394 180 loaded at the same time. This option is enabled when the MATCH Vamp
Chris@394 181 plugin is installed. When alignment is switched on and more than one
Chris@394 182 audio file is open, SV will assume that all open files are
Chris@394 183 differently timed performances of the same work, and will calculate
Chris@394 184 time alignments for them. Playback will then play only a single file
Chris@394 185 at a time, and the playback cursors in other files will track at the
Chris@394 186 varying speeds to try to ensure that each is at the same point in the
Chris@394 187 underlying score. This enables effective comparison of several such
Chris@394 188 files, as well as a meaningful way to switch from one performance to
Chris@394 189 another during playback (ensuring that the switch happens at the
Chris@394 190 correct point in the performance being switched to).
Chris@394 191
Chris@394 192 - There is a new Image layer, which can display images from the
Chris@394 193 local filesystem or retrieved via HTTP or FTP.
Chris@394 194
Chris@394 195 - A new measurement tool has been added. With the measurement tool
Chris@394 196 selected, dragging in a pane draws a rectangle labelled with the
Chris@394 197 scale values for its start and end corners and its size. You can
Chris@394 198 have any number of measurements present at once; they are associated
Chris@394 199 with the top layer, their scale values depend on the scale for that
Chris@394 200 layer, and they are only shown when that layer is at the top and the
Chris@394 201 measurement tool is active. Measurements are saved and reloaded in
Chris@394 202 the session file. Drawing measurements can be undone and redone, and
Chris@394 203 a measurement can be deleted by hitting Del when highlighted. Note
Chris@394 204 that the measurement tool shows the scale values associated with the
Chris@394 205 pixel positions of the mouse when dragging, not any values associated
Chris@394 206 with actual features present in the audio or its analysis (e.g. the
Chris@394 207 values are not rounded to the nearest spectrogram bin).
Chris@394 208
Chris@394 209 - You can double-click using the measurement tool in the spectrogram
Chris@394 210 to get an instant measurement rectangle for a feature. This is a
Chris@394 211 purely graphical feature that works by calculating the boundary of a
Chris@394 212 contiguous region of pixels "similar to" the one you double-clicked
Chris@394 213 on; it does not use audio analysis. Adjusting the gain and colour
Chris@394 214 scheme etc of the spectrogram will (by design) affect the
Chris@394 215 measurements obtained this way.
Chris@394 216
Chris@394 217 - The spectrum can now optionally show frequency estimates of peaks
Chris@394 218 aligned with a piano keyboard along the horizontal axis (this needs
Chris@394 219 some refinement).
Chris@394 220
Chris@394 221 - The harmonic cursor in the spectrogram has moved from the Select
Chris@394 222 tool to the Measurement tool. There is now a similar harmonic cursor
Chris@394 223 in the spectrum. Both of them show more information as text
Chris@394 224 alongside the cursor than previously.
Chris@394 225
Chris@394 226 - There is a new Erase tool for erasing individual points from an
Chris@394 227 editable layer.
Chris@394 228
Chris@394 229 - Several keyboard shortcuts have changed -- all of the Alt+key
Chris@394 230 shortcuts now either use Ctrl or a plain keypress with no modifier,
Chris@394 231 to avoid clashes with window manager shortcuts and to make them
Chris@394 232 easier to use and remember
Chris@394 233
Chris@394 234 - The playback controls are now in a Playback menu as well as the
Chris@394 235 toolbar.
Chris@394 236
Chris@394 237 - There is a new key and mouse control reference under Help (or press
Chris@394 238 F2).
Chris@394 239
Chris@394 240 - You can double-click on a pane in navigate mode to jump to a time.
Chris@394 241
Chris@394 242 - All of the single-colour layers (waveform, time values etc) now
Chris@394 243 allow you to define your own colours as well as using the built-in
Chris@394 244 set. The colour of a layer is now shown next to its name on the pane.
Chris@394 245
Chris@394 246 - When you add a new single-colour layer it will use a default colour
Chris@394 247 that is not yet in use in another layer (if there is one).
Chris@394 248
Chris@394 249 - Single-colour layers can now optionally have black backgrounds (with
Chris@394 250 a set of lighter colours in the default colour palette that use black
Chris@394 251 backgrounds by default).
Chris@394 252
Chris@394 253 - There's a new Printer colour scheme in the spectrogram with only a
Chris@394 254 small number of grey shades.
Chris@394 255
Chris@394 256 - Vertical zoom in a log-scaled spectrogram is much more intuitive;
Chris@394 257 it now leaves the point that was in the centre of the visible area in
Chris@394 258 the centre after zoom, instead of the point that was in the centre of
Chris@394 259 the linear range corresponding to the visible area.
Chris@394 260
Chris@394 261 - You can now turn a colour 3d plot layer upside down by clicking the
Chris@394 262 Invert Vertical Scale button.
Chris@394 263
Chris@394 264 - There's a new Layer Summary window which shows the panes and
Chris@394 265 layer data in a tree layout. This is very simplistic at the moment.
Chris@394 266
Chris@394 267 - Each pane now has an [X] button at its top left, which removes that
Chris@394 268 pane when clicked.
Chris@394 269
Chris@394 270 - There's a new Solo play mode toggle button; when active, only the
Chris@394 271 currently selected pane is played. This is also the default when
Chris@394 272 time alignment is in use.
Chris@394 273
Chris@394 274 - Rewind/ffwd now stay confined to the selection if Play Selection is
Chris@394 275 enabled; also, the rewind and ffwd "one step" buttons are now enabled
Chris@394 276 even if there is no time instants layer for them to align to (they
Chris@394 277 align to the time ruler instead and so jump in steps of a size
Chris@394 278 dependent on the zoom level).
Chris@394 279
Chris@394 280 - You can now export note layers to MIDI.
Chris@394 281
Chris@394 282 - MIDI note velocity is partially supported. Note velocity is
Chris@394 283 retained when importing and exporting MIDI and is used in playback,
Chris@394 284 but it is not yet shown in the display and cannot yet be edited.
Chris@394 285
Chris@394 286 - You can now drag-and-drop files (of whatever type) onto SV from
Chris@394 287 other programs such as file managers or web browsers.
Chris@394 288
Chris@394 289 - mp3 files (and Ogg, but they aren't supported on Windows at the
Chris@394 290 moment) are now decoded in a background thread so you can see the
Chris@394 291 start of the track without waiting for the rest to decode.
Chris@394 292
Chris@394 293 - Mac builds of SV can now load AAC/mp4 files and anything else
Chris@394 294 supported by QuickTime.
Chris@394 295
Chris@394 296 - There is now an option to resample audio files on import if they
Chris@394 297 don't match the samplerate of the first file loaded. By default this
Chris@394 298 is switched off, as it affects the visible waveform. The default
Chris@394 299 behaviour is unchanged (play at the wrong rate). There is still no
Chris@394 300 option to handle multiple rates "correctly" (i.e. by resampling
Chris@394 301 on playback and showing the waveforms at different resolutions
Chris@394 302 according to each one's underlying rate) and there probably never
Chris@394 303 will be.
Chris@394 304
Chris@394 305 - SV can now open .m3u playlist files, though it's a hazardous thing
Chris@394 306 to do as it simply loads all the files in the playlist at once.
Chris@394 307
Chris@394 308 - SV now has various options for how to number tapped time instants
Chris@394 309 (bar/beat, plain counter, time in seconds, tempo etc).
Chris@394 310
Chris@394 311 - The official builds use Qt 4.3, which fixes some nasty
Chris@394 312 bugs in the file dialog that the version 1.0 builds suffered from.
Chris@394 313
