A MovieAudio is actually any source that provides a sequence of audio samples. That could include an AVI file, a microphone, or an internet TV station.
The difference between a MovieAudio and a
MovieAudioCursor
is like the difference between a filename and a file handle. The MovieAudio just indicates a particular movie. TheMovieAudioCursor
is what allows access.Inheritance diagram
