Hi at all, i have done an Iphone project. It read 3 or more .caf files in a background process with AudioUnit and AUGraph to mix them.
/usr/bin/afconvert -f caff -d LEI16 myfile.mp3 myfile.caf
I have the control of the Audio of all the files and the control af the global volume. The program is ok when audio files are not compressed (caf). (BUT THAT FILES ARE TOO MUCH BIG... about 13 Mb x file and i must download them from Internet)
If i use mp3 files, i have files that are smaller. i sow that iphone is very slow to load 3 or four files at time becouse it need to decompress them i think!
What is the best way to mix files using AUGRAPH?????... What kind of format is better to use??
