System for switching between buffers when receiving bursty audio by computing loop jump indicator plus loop start address for read operations in selected buffer

摘要

Method and apparatus for wavetable style playback of audio data received from a bursty source is disclosed. Incoming audio data is directed to one buffer while another buffer is available for playback to permit simultaneous buffer filling and playback. When a buffer becomes full of newly received data, the buffers exchange roles. Methods and apparatus for efficiently and accurately controlling addressing of the buffers for playback are disclosed.
