Abstract
Late audio buffer processing for intelligently muting audio output when audio buffers are not read fast enough from disk into digital signal processing (DSP) memory. Given a playback audio recorder, each channel of audio is associated with a forward and a reverse late threshold signals which are enabled when the processing of an audio buffer for that channel is delayed. When an audio buffer for that channel is delayed, the late threshold signal sets in motion the muting of that specific audio channel for a predetermined amount of time. If and when the system catches up, normal playback resumes. Otherwise, the channel stays muted.
