The Audio Compatibility Patch (ACP) Magisk module is a specialized utility designed to fix "silent" audio processing issues in music and streaming apps like Spotify or Pandora when using equalizers like ViPER4Android.
The most interesting "feature" isn't a setting in an app, but the Zip-Name Trigger system used during installation. The "Interactive" Installation Feature
