QUESTION

iOS: Apply audio modifications to Music library content

Asked 2021-Nov-16 at 02:54

I'm working on an iOS/Flutter application, and am trying to work out if it's possible to play audio from the Music library on iOS with audio modifications (e. g. equalization settings) applied.

It seems like I'm looking for a solution that can work with MPMusicPlayerController, since that appears to be the strategy for playing local audio from the user's iOS Music library. I can find examples of applying EQ to audio on iOS (e. g. using AVAudioUnitEQ and AVAudioEngine: SO link, tutorial), but I'm unable to find any resources to help me understand if it's possible to bridge the gap between these resources.

Flutter specific context:

There are Flutter plugins that provide some of the functionality I'm looking for, but don't appear to work together. For example, the just_audio plugin has a robust set of features for modifying audio, but does not work with the local Music application on iOS/MPMusicPlayerController. Other plugins that do work with MPMusicPlayerController, like playify, do not have the ability to modify/transform the audio.

Even though I'm working with Flutter, any general advice on the iOS side would be very helpful. I appreciate any insight someone with more knowledge may be able to share with me!

Updating with my own answer here for future people: It looks like my only path forward (for now) is leaning into into AVAudioEngine directly. This is the rough POC that worked for me:
