annotate audioio/AudioCoreAudioTarget.h @ 180:98ba77e0d897
* Merge from sv-match-alignment branch (excluding alignment-specific document).
- add aggregate wave model (not yet complete enough to be added as a true
model in a layer, but there's potential)
- add play solo mode
- add alignment model -- unused in plain SV
- fix two plugin leaks
- add m3u playlist support (opens all files at once, potentially hazardous)
- fix retrieval of pre-encoded URLs
- add ability to resample audio files on import, so as to match rates with
other files previously loaded; add preference for same
- add preliminary support in transform code for range and rate of transform
input
- reorganise preferences dialog, move dark-background option to preferences,
add option for temporary directory location
