Audio Unit looks like a Core audio concept, but I see that it has many custom configurations, so I'm thinking can I use audio unit's setting on an AVAudioPlayer? but first, what is an audio unit?

    Audio Units are interface services provided by the operating system to generate, process, receive, or otherwise manipulate streams of audio in near-real-time with minimal latency.

From Apple documentation:

"iOS provides audio processing plug-ins that support mixing, equalization, format conversion, and realtime input/output for recording, playback, offline rendering, and live conversation such as for VoIP (Voice over Internet Protocol). You can dynamically load and use these powerful and flexible plug-ins, known as audio units"
