Hello,
As of right now I am using ffmpeg to convert from .mp3 --> to .aiff but I would like a native way to do this in xcode but i do not understand how to use AudioConverter.h in AudioToolbox soo if someone could please help me I would be really appreciative.
Thank You Enea
I think the real question is why would you want to? The iphone and AudioQueue has full mp3 support for playback and mixing. I know of no way to do this on the fly in the iPhone. It is a fairly processor intensive task and I doubt you could do it efficiently on the iPhone anyway.
You can use ExtAudioFile to open and convert the file to CAF with PCM data.
Lucius can you please give me some more details i have not worked with sound that much and cannot seem to find any tutorials online
ExtAudioFile can do a fantastic job of this. One reason to take some compressed formats like MP3 and convert to PCM is that there is much less of a latency when playing the sound. An MP3 sound effect, for example, can take close to a second to start playing back, when the same sound in PCM could start almost immediately. I know since I am converting my sounds to PCM at launch time and eliminating the delays I was plagued with.
Go download iPhoneExtAudioFileConvertTest and you will find everything you need to do your own conversions
