iPhone Audio Effects

I'm searching for Library, Framework or SDK for add audio effects in Ob开发者_StackOverflow社区jective-C, like reverber, echo etc...

Somebody knowns something?

Probably the best solution is to find a C library for the effects that you need. (Objective C code can call C library routines without any difficulty).

FMOD is a great suite of audio processing effects and runs well on iPhone.

There are a few good open-source collections, mda-vst, for example, but you'll have to hook them into iOS audio frameworks yourself. I'm not aware of any that are ready to go for iOS off the shelf.
