Abstract
An audio processing circuit may have a first path for processing multi-bit audio signals in parallel with a second path for processing single-bit audio signals. The parallel paths may share a common input node for receiving audio data and a common output node for reproducing audio at a transducer. Each path may have a volume control for adjusting an output of the path. The audio processing circuit may determine a type of an audio signal received at the input. The path not corresponding to the detected type of the audio signal is muted, and the path corresponding to the detected type of audio signal is unmuted.
