How to add iPod EQ when playing audio with AVPlayer?

Question

I am able to play songs from iPod library using AVPlayer class. Now what I want to do is to insert equalizer to the audio produced.

Anybody has experienced in doing this

Answer 1

There is no way to play MPMediaItem and adding sound equalizer with AVPlayer. We have to use Audio Unit processing.

Answer 2

I have done this leveraging a class provided in the Apple Samples:

Hope this helps.
