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@407 9 - The CSV import dialog has been overhauled, allowing more flexible
Chris@407 10 selection of purpose for each column
Chris@407 11
Chris@394 12 - Text overlays are now easier to read on dark backgrounds
Chris@394 13
Chris@394 14 - Hidden layers are now ignored when exporting an image (Dan Stowell)
Chris@394 15
Chris@394 16 - A crash when starting a new session or exiting the application
Chris@394 17 after loading a session with saved alignment data has been fixed
Chris@394 18
Chris@394 19 - The duplication of right-button menu functions when multiple files
Chris@394 20 were loaded has been fixed
Chris@394 21
Chris@394 22 - The layer-add menu functions now have shortcuts (Dan Stowell)
Chris@394 23
Chris@394 24 - The codebase has been reorganised into libraries and a configure
Chris@394 25 step added. It should be easier to build and maintain on OS/X and
Chris@394 26 Linux than previously, although it won't make much difference on
Chris@394 27 Windows.
Chris@394 28
Chris@397 29 - A Czech translation is now included (thanks to Pavel Fric).
Chris@397 30
Chris@394 31 Changes in Sonic Visualiser 1.7.2 since the previous release 1.7.1:
Chris@394 32
Chris@394 33 - The time-value layer now has an origin line and an option to
Chris@394 34 show derivatives (change from one point to the next) rather than
Chris@394 35 raw values
Chris@394 36
Chris@394 37 - A static initialiser race has been fixed, possibly fixing an
Chris@394 38 occasional crash on startup in Windows
Chris@394 39
Chris@394 40 - A crash when pressing Play straight after New Session has been
Chris@394 41 fixed
Chris@394 42
Chris@394 43 Changes in Sonic Visualiser 1.7.1 since the previous release 1.7:
Chris@394 44
Chris@394 45 - The RDF importer does a better job of assigning labels to layers,
Chris@394 46 layers to panes, and values to labelled regions
Chris@394 47
Chris@394 48 - Interactive editing in the Text layer benefits from the same
Chris@394 49 improvements as made in 1.7 to Note and Region layers
Chris@394 50
Chris@394 51 - The layer data editor window has a text search feature
Chris@394 52
Chris@394 53 - The main window status bar now shows the last label to have passed
Chris@394 54 the playback position in the current layer, at the right end of the
Chris@394 55 status bar
Chris@394 56
Chris@394 57 - The Russian translation has been updated (thanks Alexandre)
Chris@394 58
Chris@394 59 Changes in Sonic Visualiser 1.7 since the previous release 1.6:
Chris@394 60
Chris@394 61 - A new "Insert Item At Selection" function on the Edit menu
Chris@394 62 can be used to create Note and Region layer items whose time
Chris@394 63 extents correspond to the current selection(s)
Chris@394 64
Chris@394 65 - Interactively editing points in the Note and Region layers
Chris@394 66 now works much more smoothly
Chris@394 67
Chris@394 68 - SV can now import MIDI files that use SMPTE timecode for event
Chris@394 69 timing (importing MIDI files using with the more common
Chris@394 70 timebase-based timing was already supported)
Chris@394 71
Chris@394 72 - Time values throughout the display may optionally be shown in
Chris@394 73 seconds and frames at various frame rates
Chris@394 74
Chris@394 75 - A crash on exit in Windows has been fixed
Chris@394 76
Chris@394 77 - A very unobtrusive user survey is now included
Chris@394 78
Chris@394 79 - Various other bug fixes.
Chris@394 80
Chris@394 81 Changes in Sonic Visualiser 1.6 since the previous release 1.5:
Chris@394 82
Chris@394 83 - The Colour 3D Plot layer now supports logarithmic vertical
Chris@394 84 scale and linear interpolation options.
Chris@394 85
Chris@394 86 - A new colour scheme (High Gain) has been added for spectrogram
Chris@394 87 and Colour 3D Plot, which improves readability for some data.
Chris@394 88
Chris@394 89 - Further performance improvements have been made to Colour 3D
Chris@394 90 Plot.
Chris@394 91
Chris@394 92 - Various other bug fixes.
Chris@394 93
Chris@394 94 Changes in Sonic Visualiser 1.5 since the previous version 1.4:
Chris@394 95
Chris@394 96 - You can now insert time instants, time values, and notes using
Chris@394 97 a MIDI device during playback. If a time value or note layer is
Chris@394 98 current it will be used for insertion (giving a value equal to
Chris@394 99 the pitch class, or the played note, respectively); otherwise an
Chris@394 100 existing or new time instants layer will be used just as it is
Chris@394 101 when inserting instants using the PC keyboard. Using a MIDI
Chris@394 102 device should give better timing than using the PC keyboard.
Chris@394 103
Chris@394 104 - There is a new Activity Log window with a (purely informative) list
Chris@394 105 of events and user interactions that happen while SV is running.
Chris@394 106
Chris@394 107 - The spectrogram has somewhat improved graphical scaling, and
Chris@394 108 this is now the default (being much faster than the 4x oversampled
Chris@394 109 method). The previous default is still available as a preference.
Chris@394 110
Chris@394 111 - Visualisation of very dense colour plots (such as spectrograms
Chris@394 112 calculated by plugins) is substantially faster in this release.
Chris@394 113
Chris@394 114 - Spectrogram display is now faster in many circumstances.
Chris@394 115
Chris@394 116 - Alignment using the MATCH plugin is faster on OS/X than before.
Chris@394 117
Chris@394 118 - SV will take into account RDF plugin descriptions, if available,
Chris@394 119 in order to make somewhat better decisions about display of plugin
Chris@394 120 outputs (for example, placing segmentation data into a layer with
Chris@394 121 segmentation plot type).
Chris@394 122
Chris@394 123 - You can now switch layers by clicking on the spare area at the left
Chris@394 124 end of the pane that is also used for the current pane indicator.
Chris@394 125
Chris@394 126 - The vertical black lines dividing segments in the time value
Chris@394 127 layer's segmentation plot style are now optional.
Chris@394 128
Chris@394 129 - Several widget layout bugs on OS/X have been fixed.
Chris@394 130
Chris@394 131 - Several serious crashing, deadlock, and data corruption bugs have
Chris@394 132 been fixed.
Chris@394 133
Chris@394 134
Chris@394 135 New features in Sonic Visualiser 1.4 since the previous version 1.3:
Chris@394 136
Chris@394 137 - SV now has a Region layer type, used for display of features with
Chris@394 138 durations. It also supports Vamp v2.0 plugins that provide durations
Chris@394 139 for features.
Chris@394 140
Chris@394 141 - Layer data can now be imported from RDF described using the Audio
Chris@394 142 Features Ontology, as well as from the existing text file types. SV
Chris@394 143 can also export annotation layer data to RDF/Turtle, although in a
Chris@394 144 somewhat simplistic manner at present.
Chris@394 145
Chris@394 146 - You can search for transforms by text in the new "Find a Transform"
Chris@394 147 dialog. This searches both installed plugins, and plugins that have
Chris@394 148 not been installed but that have descriptions available on the
Chris@394 149 semantic web.
Chris@394 150
Chris@394 151 - You can now zoom and scroll vertically in the time-value, note,
Chris@394 152 and colour 3d plot layers.
Chris@394 153
Chris@394 154 - Sonic Visualiser can now load sessions from uncompressed XML files
Chris@394 155 as well as its own compressed-XML .sv format. Files with extension
Chris@394 156 .xml that contain suitable session data will be loaded as sessions.
Chris@394 157 Note that .xml extension files still do not show up in the default
Chris@394 158 file load filter. This is intentional, as there may be any kind of
Chris@394 159 data in them -- if you want to load uncompressed session files from
Chris@394 160 XML, you need to know you're doing it.
Chris@394 161
Chris@394 162 - Several crashes and other bugs have been fixed.
Chris@394 163
Chris@394 164 Changes in Sonic Visualiser 1.3 since the previous version 1.2:
Chris@394 165
Chris@394 166 - There is a new spreadsheet-style data viewer and editor for
Chris@394 167 viewing and editing the data in some types of annotation layer.
Chris@394 168
Chris@394 169 - Alignments are now saved to the session file.
Chris@394 170
Chris@394 171 - The spectrogram layer is usually somewhat faster than it was.
Chris@394 172
Chris@394 173 - You can now hold Shift while dragging to move an item, in order
Chris@394 174 to override the initial drag resistance introduced in 1.2.
Chris@394 175
Chris@394 176 - The gross mis-labelling of time lines in the ruler has been fixed.
Chris@394 177
Chris@394 178 - There is a new, somewhat provisional PulseAudio output driver.
Chris@394 179
Chris@394 180 - Several other bug fixes.
Chris@394 181
Chris@394 182 New features in Sonic Visualiser 1.2, since the previous version 1.0:
Chris@394 183
Chris@394 184 - SV now supports time-alignment of multiple performances of a work
Chris@394 185 loaded at the same time. This option is enabled when the MATCH Vamp
Chris@394 186 plugin is installed. When alignment is switched on and more than one
Chris@394 187 audio file is open, SV will assume that all open files are
Chris@394 188 differently timed performances of the same work, and will calculate
Chris@394 189 time alignments for them. Playback will then play only a single file
Chris@394 190 at a time, and the playback cursors in other files will track at the
Chris@394 191 varying speeds to try to ensure that each is at the same point in the
Chris@394 192 underlying score. This enables effective comparison of several such
Chris@394 193 files, as well as a meaningful way to switch from one performance to
Chris@394 194 another during playback (ensuring that the switch happens at the
Chris@394 195 correct point in the performance being switched to).
Chris@394 196
Chris@394 197 - There is a new Image layer, which can display images from the
Chris@394 198 local filesystem or retrieved via HTTP or FTP.
Chris@394 199
Chris@394 200 - A new measurement tool has been added. With the measurement tool
Chris@394 201 selected, dragging in a pane draws a rectangle labelled with the
Chris@394 202 scale values for its start and end corners and its size. You can
Chris@394 203 have any number of measurements present at once; they are associated
Chris@394 204 with the top layer, their scale values depend on the scale for that
Chris@394 205 layer, and they are only shown when that layer is at the top and the
Chris@394 206 measurement tool is active. Measurements are saved and reloaded in
Chris@394 207 the session file. Drawing measurements can be undone and redone, and
Chris@394 208 a measurement can be deleted by hitting Del when highlighted. Note
Chris@394 209 that the measurement tool shows the scale values associated with the
Chris@394 210 pixel positions of the mouse when dragging, not any values associated
Chris@394 211 with actual features present in the audio or its analysis (e.g. the
Chris@394 212 values are not rounded to the nearest spectrogram bin).
Chris@394 213
Chris@394 214 - You can double-click using the measurement tool in the spectrogram
Chris@394 215 to get an instant measurement rectangle for a feature. This is a
Chris@394 216 purely graphical feature that works by calculating the boundary of a
Chris@394 217 contiguous region of pixels "similar to" the one you double-clicked
Chris@394 218 on; it does not use audio analysis. Adjusting the gain and colour
Chris@394 219 scheme etc of the spectrogram will (by design) affect the
Chris@394 220 measurements obtained this way.
Chris@394 221
Chris@394 222 - The spectrum can now optionally show frequency estimates of peaks
Chris@394 223 aligned with a piano keyboard along the horizontal axis (this needs
Chris@394 224 some refinement).
Chris@394 225
Chris@394 226 - The harmonic cursor in the spectrogram has moved from the Select
Chris@394 227 tool to the Measurement tool. There is now a similar harmonic cursor
Chris@394 228 in the spectrum. Both of them show more information as text
Chris@394 229 alongside the cursor than previously.
Chris@394 230
Chris@394 231 - There is a new Erase tool for erasing individual points from an
Chris@394 232 editable layer.
Chris@394 233
Chris@394 234 - Several keyboard shortcuts have changed -- all of the Alt+key
Chris@394 235 shortcuts now either use Ctrl or a plain keypress with no modifier,
Chris@394 236 to avoid clashes with window manager shortcuts and to make them
Chris@394 237 easier to use and remember
Chris@394 238
Chris@394 239 - The playback controls are now in a Playback menu as well as the
Chris@394 240 toolbar.
Chris@394 241
Chris@394 242 - There is a new key and mouse control reference under Help (or press
Chris@394 243 F2).
Chris@394 244
Chris@394 245 - You can double-click on a pane in navigate mode to jump to a time.
Chris@394 246
Chris@394 247 - All of the single-colour layers (waveform, time values etc) now
Chris@394 248 allow you to define your own colours as well as using the built-in
Chris@394 249 set. The colour of a layer is now shown next to its name on the pane.
Chris@394 250
Chris@394 251 - When you add a new single-colour layer it will use a default colour
Chris@394 252 that is not yet in use in another layer (if there is one).
Chris@394 253
Chris@394 254 - Single-colour layers can now optionally have black backgrounds (with
Chris@394 255 a set of lighter colours in the default colour palette that use black
Chris@394 256 backgrounds by default).
Chris@394 257
Chris@394 258 - There's a new Printer colour scheme in the spectrogram with only a
Chris@394 259 small number of grey shades.
Chris@394 260
Chris@394 261 - Vertical zoom in a log-scaled spectrogram is much more intuitive;
Chris@394 262 it now leaves the point that was in the centre of the visible area in
Chris@394 263 the centre after zoom, instead of the point that was in the centre of
Chris@394 264 the linear range corresponding to the visible area.
Chris@394 265
Chris@394 266 - You can now turn a colour 3d plot layer upside down by clicking the
Chris@394 267 Invert Vertical Scale button.
Chris@394 268
Chris@394 269 - There's a new Layer Summary window which shows the panes and
Chris@394 270 layer data in a tree layout. This is very simplistic at the moment.
Chris@394 271
Chris@394 272 - Each pane now has an [X] button at its top left, which removes that
Chris@394 273 pane when clicked.
Chris@394 274
Chris@394 275 - There's a new Solo play mode toggle button; when active, only the
Chris@394 276 currently selected pane is played. This is also the default when
Chris@394 277 time alignment is in use.
Chris@394 278
Chris@394 279 - Rewind/ffwd now stay confined to the selection if Play Selection is
Chris@394 280 enabled; also, the rewind and ffwd "one step" buttons are now enabled
Chris@394 281 even if there is no time instants layer for them to align to (they
Chris@394 282 align to the time ruler instead and so jump in steps of a size
Chris@394 283 dependent on the zoom level).
Chris@394 284
Chris@394 285 - You can now export note layers to MIDI.
Chris@394 286
Chris@394 287 - MIDI note velocity is partially supported. Note velocity is
Chris@394 288 retained when importing and exporting MIDI and is used in playback,
Chris@394 289 but it is not yet shown in the display and cannot yet be edited.
Chris@394 290
Chris@394 291 - You can now drag-and-drop files (of whatever type) onto SV from
Chris@394 292 other programs such as file managers or web browsers.
Chris@394 293
Chris@394 294 - mp3 files (and Ogg, but they aren't supported on Windows at the
Chris@394 295 moment) are now decoded in a background thread so you can see the
Chris@394 296 start of the track without waiting for the rest to decode.
Chris@394 297
Chris@394 298 - Mac builds of SV can now load AAC/mp4 files and anything else
Chris@394 299 supported by QuickTime.
Chris@394 300
Chris@394 301 - There is now an option to resample audio files on import if they
Chris@394 302 don't match the samplerate of the first file loaded. By default this
Chris@394 303 is switched off, as it affects the visible waveform. The default
Chris@394 304 behaviour is unchanged (play at the wrong rate). There is still no
Chris@394 305 option to handle multiple rates "correctly" (i.e. by resampling
Chris@394 306 on playback and showing the waveforms at different resolutions
Chris@394 307 according to each one's underlying rate) and there probably never
Chris@394 308 will be.
Chris@394 309
Chris@394 310 - SV can now open .m3u playlist files, though it's a hazardous thing
Chris@394 311 to do as it simply loads all the files in the playlist at once.
Chris@394 312
Chris@394 313 - SV now has various options for how to number tapped time instants
Chris@394 314 (bar/beat, plain counter, time in seconds, tempo etc).
Chris@394 315
Chris@394 316 - The official builds use Qt 4.3, which fixes some nasty
Chris@394 317 bugs in the file dialog that the version 1.0 builds suffered from.
Chris@394 318
