Sonic Visualiser 4.5 + x64

- Add option to switch off the interpolation used in the waveform
view for zoom levels closer than one pixel per frame: sometimes it
can be an unnecessary distraction. With interpolation switched off,
the individual samples are shown as unconnected points instead

- Make it possible to toggle segment colouring in the segmentation
view of the time value layer, as well as toggling segment division
lines

- When importing CSV files, if a column heading indicates a likely
unit for the column, use it by default; also remember last user
settings for the import dialog

- Ensure the Choose Default Template option on the templates menu can
be reached even when no file is loaded

- Give the spectrum layer the same effective scale range as it had
before the dB scale fix in v4.4, fixing the accidental halving of
the visible range for that layer in v4.4

- Fix hang when opening two plugin parameter dialogs at once

- Fix crash when rendering slice or spectrum layers scrolled to
earlier than the start of the audio or later than the end

- Fix crash when more than one audio file is supplied at the command
line with a default session template that requires regenerating one
or more feature extraction layers and layer generation produces an
error or warning

- Fix failure to exit fully if the window is closed before plugin
scan is complete at startup

34 - Add Box annotation layer type, typically used for time-frequency
5   boxes to be annotated over a spectrogram. Because this introduces a
6   new layer type into the session file format, the major version
7   number has been bumped to v4.0. Sessions saved from v4.0 can still
8   be opened in earlier versions of Sonic Visualiser, but any Box
9   layers will not be loaded
1011 - Fix behaviour of auto-align layers on top of waveform: they can now
12   be aligned in the vertical scale, if they have a unit of V and the
13   waveform is of a single channel in linear or dB mode
1415 - Make the UI more readable in macOS "dark mode"
1617 - Fix sluggishness in starting and stopping playback when using
18   PulseAudio v13.0+

4
- Add ability to record audio, and ability to change the audio device
5
for playback or recording in the preferences
6
7
- Add complete support for high-resolution (Hi-DPI or retina)
8
displays, including for layer data rendering as well as UI controls
9
and icons. This makes the biggest difference when using a retina
10
Mac, on which previous versions did not render layer data at retina
11
resolution, but it also improves scaling and rendering of UI
12
elements on Hi-DPI displays on Windows and Linux
13
14
- Add ability to export scalable (SVG) image files
15
16
- Run plugins in a separate process, so that if a plugin crashes, it
17
no longer brings down Sonic Visualiser with it. In every other
18
respect the behaviour should be unchanged
19
20
- Scan plugins on startup in a separate process, and report on any
21
that crash or won't load
22
23
- Add ability to open, display, and analyse very long audio files (of
24
more than 2^32 sample frames)
25
26
- Change mp3 file loading so as to compensate for encoder/decoder
27
delay and padding (using "gapless playback" logic). While this is a
28
real improvement, unfortunately it does mean that the initial
29
padding in mp3 file load has changed from previous versions, which
30
may mean some sessions saved in previous versions are no longer
31
correctly aligned. It's not a great idea to use mp3 as a file
32
format of record, because of differences like this between
33
decoders. The previous behaviour is still available as a preference.
34
35
- Add new Hybrid normalisation type for spectrogram and colour 3d
36
plot layers. This normalises each column to its peak value and then
37
scales the normalised values by the log of the peak in order to
38
restore some distinction in scale between columns with different
39
levels. It can provide quite visually clear results.
40
41
- Add function to subdivide time instant layers into regular
42
intervals (and its inverse)
43
44
- Add new preference for default colour scales
45
46
- Add a basic ability to zoom (in the frequency axis) to the spectrum
47
48
- Switch to using combined level/pan controls in layer property boxes
49
and for the main volume control
50
51
- Make CSV file reader better able to handle files with varying
52
numbers of columns
53
54
- Fix a number of problems on Windows with loading and saving some
55
file formats to filenames not representable in system codepage
56
57
- Add "What's New" dialog
58
59
- Finally switch the Windows build to 64-bit by default (with
60
adapters to run either 32- or 64-bit plugins)

- Add unit-converter dialog, for converting between various pitch and timing units

- Fix failure to reload note layers from session file

- Use a more sensible scale for the play-speed dial

- Fix crash when importing very wide CSV files

- Fix generation of wrong layer type from some CSV files

- Fix failure to export last instant in a time-instant layer

Fix a crash when rendering certain colour 3d plot layers

- Add support for left/right scrolling using a two-finger touchpad
5
gesture (where available)
6
7
- Make the octave numbering into a configurable option, and change
8
the default. Previously Sonic Visualiser labelled middle-C as "C3";
9
now it labels middle-C as "C4", a more common standard in the world
10
outside MIDI sequencer software. The previous system is available
11
as an option in the Preferences. This affects only the visible
12
labels: there is no change to analysis or to the file format
13
14
- Sonify time-value layers. Any time-value curve whose scale unit is
15
set to Hz will now acquire a playback toggle control; this control
16
is off by default, but if it is switched on, the curve will be
17
played back using a variable-frequency sound generator
18
19
- Add support for playback of note layers with non-MIDI frequencies
20
(formerly the note playback was limited to exact MIDI pitch)
21
22
- Change the default playback sample for note layers from piano to an
23
electric piano with sustain. The piano sample is still available,
24
and any sessions saved using it should continue to use it
25
26
- Add keyboard shortcuts to cycle the current layer (in addition to
27
the existing ones to cycle the current pane)
28
29
- Fix various bugs related to layer ordering: layer tabs re-ordering
30
themselves randomly when new layer added, layers being ordered
31
randomly when saving and reloading a session
32
33
- Fix incorrect interaction with non-Unicode usernames when creating
34
temporary and template directories on Windows
35
36
- Shade the start and end of the main audio file, to make them easier
37
to see for files that start or end in silence
38
39
- Speed up rendering and scrolling in time-value layers
40
41
- Make it possible to import CSV files directly into Note layers by
42
adding Pitch as a data type in the CSV file import dialog
43
44
- Fix problems with keyboard shortcuts when using Qt5 on OS/X. This
45
is the first release in which the official builds use Qt5 for all
46
platforms.

- Add a startup welcome dialog that also explains what SV makes

network connections for and allows user to forbid them

- Add "Export Audio Data" feature

- Show piano keyboard scale in note and time-value layers as well

as spectrogram, where vertical scale is log Hz; also show

numerical scale in note and region layers when not auto-aligned

- Speed up CSV file import and avoid showing crazily wide window

for CSV file format dialog when file has lots of columns

- Fix incorrectly saved window geometry when exiting from maximised

state

- Reduce number of timer wakeups when idle

- Add American English translation and make choice of translation

into a preference (defaulting to system locale)

- Permit installation to non-default location with Windows installer

- Fix inaccurate scale auto-align between time-value layers and
8
others
9
- Fix failure to open files specified on command line (or via

Open With) on Windows

- Reset cyclical counters and switch back to navigate mode when
12
a new session is started

- Fix incorrect handling of FixedSampleRate outputs (Vamp SDK fix)

- Add discrete-curve mode for time-value layers (for curves with gaps)
8
- Update code to build against Qt5
