Hello all,
I am new to Core Audio and would like to take a movies sound and
stretch the duration preserving pitch.
I understand Tiger has an audio unit for this, but I don't know its
subtype.
Presumably I have to start an audio extraction session, feed the data
to the audio unit and write to a file. What is the simplest way to
write to a file? Does an audio unit exist that writes to a file?
BTW, I don't think such a thing as an movie audio addition API exists,
does it? So I will have to copy the sound file to the movie in the end.
TIA,
Jan
