I see the current playaudio function merely calls
paplay. I take it the project would involve creating a C
extension? I am thinking maybe a simple http://www.music.mcgill.ca/~gary/rtaudio/
playback demonstration would be a good thing to add to the
proposal?
To me, the project involves :
- choosing an open source, cross platform library that handles
at least synchronous recording and playback.
- packaging the necessary functions into an octave class
- writing the ML compatible interfaces to the audiorecorder,
audioplayer classes and play/record ... methods.
Among the candidate libraries :
- rtaudio
(native c++): (+) seams easy to learn (-) not much active.
- portaudio (c with c++
binding): (+) widely used and active, (-) c++ binding is not as
well documented as native c.
- Qt's multimedia
classes (native c++): (+) Qt, as octave's GUI, (-) not as
low-level as above mentioned (but maybe enough)
For packaging in an octave class there are examples in octave-forge
(see e.g. serial_class in the instrument-control
package). The resulting octave_audio class could then be used
to write the interface to core audiorecorder and audioplayer
classes.
