I am interested in doing some signal processing on the audio channels of
a QuickTime Movie. I can retrieve the
buffer using MovieAudioExtractionFillBuffer, but the available examples
specify the buffer as type Byte*. I am
interested in decomposing the buffer into the left and right channel
data sample arrays. I assume that these are 16 bit
audio samples, but I have yet to find a method that returns the two
separate (left and right) arrays or the appropriate
Cocoa data type to use with such sample data. Any ideas or examples?
Thanks,
