Answer 1

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

I recommend you to make the equalizer using NVDSP: github.com/bartolsthoorn/NVDSP It's really easy. – Torray

@bartolsthoorn how would you play songs from the iPod library with NVDSP. Novocaine does not allow you to play songs from the iPod library. Also can you provide some sample code? – Ectoblast

Fedry can you help me a lil with EQ using Novocaine? – Hinds

Answer 2

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

Hope this helps.

The sample is about displaying level meter. I cannot find anything related to equalizer. – Militia
