Hi there

I am using AAC files on my iPhone game for my music tracks.
These are sampled at 44.1KHz.

All my sound effects are uncompressed and sampled at 24KHz.
The FMOD sample rate is left at the default 24KHz.

My question:
Are my music tracks sent back into the FMOD mixer after hardware decoding?
If so I assume my music is sampled back down to 24KHz and there is an associated processing cost that could be avoided.

Can anyone confirm this is the case?

Thank you

Yes, AAC decoding is implemented as a FMOD Codec mixed by the software mixer.

Yes, some (not a lot), FMOD will decode the AAC to the sample rate stored in the file (which is most likely the source file rate). Be aware that using pitch effects on any sound will negate its saving gained by matching rates.
