How to apply audio effects in iOS

I use AVPlayer to play audio(streaming or local file). For this audio I want to apply some effects - boost volume, skip silence, reduce noise, change speed(in 0.1 intervals).

I did same thing in android by creating own player, decoding different audio formats into pcm data and then using some c libraries to modify it. It was quite complicated.

Is it possible to do with AVPlayer or how can I do that? Something like modifying audio already decoded by AVPlayer. Is there some ios api (AVAudioEngine?) or frameworks (audioKit?) which can do this?

Thanks!

IMHO the best solution is to use https://github.com/audiokit/AudioKit as it is well maintained and supports most of the requirements you listed.

Another approach is to import the C library you used in the Android project and have a wrapper around it so it can easily used in ObjectiveC/Swift. With this approach you will have less code to maintain and you guarantee similar results between the two platforms. Do you care to share more about this code ?
