\brief Utility functions for working with our wxConf (gPrefs)
|
|
|
|
|
|
Audacity uses wxWidgets' wxConfig class to handle preferences.
|
|
See Prefs.h for more information on how it works...
|
|
|
|
\verbatim
|
|
Note: The info below is very outdated and incomplete
|
|
|
|
Preference field specification:
|
|
/
|
|
Version - Audacity Version that created these prefs
|
|
DefaultOpenPath - Default directory for NEW file selector
|
|
/FileFormats
|
|
CopyOrEditUncompressedData - Copy data from uncompressed files or
|
|
[ "copy", "edit"] - edit in place?
|
|
ExportFormat_SF1 - Format to export PCM data in
|
|
(this number is a libsndfile1.0 format)
|
|
/SamplingRate
|
|
DefaultProjectSampleRate- New projects will have this rate
|
|
[ 8000, 11025, 16000, 22050, 44100, 48000 ]
|
|
/AudioIO
|
|
PlaybackDevice - device to use for playback
|
|
RecordingDevice - device to use for recording
|
|
(these are device names understood by PortAudio)
|
|
/Display
|
|
WaveformColor - 0xRRGGBB --since it will be stored in
|
|
ShadowColor - decimal, it will be somewhat
|
|
SpectrumLowColor - non-intuitive to edit, but
|
|
SpectrumHighColor - much easier to parse.
|
|
/Locale
|
|
Language - two-letter language code for translations
|
|
|
|
(*): wxGTK
|
|
(+): wxWin
|
|
($): wxMac
