Hello,
I have a string of audio units set up, a mixer -> an output(remote io)
WAV files are played fine by this, as there is no generator for file readers
in iPhone, I have WAV files stored on buffers which the mixer then pulls
off using a callback function.
I want to play MP3 files now with this as well though, so I have a
couple questions...
First, would I use a converter unit somewhere in this mix? And if so how?
Second, If the converter unit wouldnt handle this type of conversion,
would I use
AudioFile API to take MP3 files and make them PCM first?
Ideally I would like to pull parts of the MP3 , convert them to PCM
and feed them to the
mixer for various signal processing. I am just totally lost on how to
do this in iPhone
Thanks for any help!
-Russ
