New Functionality

Most of the functionality of MATLAB's audioplayer class is working now. The only two missing pieces of functionality is the ability to specify an audiorecorder object to use. I am not even fully sure what that is for yet. The other piece of missing functionality are the StartFcn, StopFcn, TimerFcn and TimerPeriod properties that require a working timer class. Other than that any code using audioplayer that works in MATLAB should work in Octave too if you compile my code from https://bitbucket.org/bucket_brigade/octave-sound. Here are some examples to try out.

octave:1> sound = randn(2, 441000) - 0.5;
octave:2> player = audioplayer(sound, 44100);
octave:3> play(player);
# wait a little bit
octave:4> pause(player);
# will pause the playback
octave:5> resume(player);
# will resume the playback where it was paused

octave:1> sound = randn(2, 441000) - 0.5;
octave:2> player = audioplayer(sound, 44100, 8);
octave:3> player.BitsPerSample
ans = 8
octave:4> player.Tag = "testing";
octave:5> player.Tag
ans = testing

You can obviously load an audio file if you have one in suitable format using octave's loadaudio function, apply some signal processing on it and play that back.
