Notes
Echo cancellation: System voice processing (echo cancellation + noise suppression for voice chat) — not Krisp-style ML denoising.
Audio file reading/writing: Read/write Core Audio formats (CAF, WAV, AIFF, m4a…).
Audio level metering: Built-in level metering on AVAudioPlayer/AVAudioRecorder.
Audio playback: AVAudioPlayer for files/buffers; AVAudioEngine for graphs. Built into the OS — no dependency.
Microphone recording: AVAudioRecorder for files; AVAudioEngine.inputNode for buffers.
Audio session management: The system audio session itself — category, activation, routing.
Spatial audio: 3D positional mixing via AVAudioEnvironmentNode and spatial mixing attributes.
Audio synthesis / DSP: Render-block synthesis via AVAudioSourceNode; AVAudioUnit hosts DSP.
