17 In recent years, audio digital signal processors (DSP) were integrated
68 streaming compressed data to a DSP, with the assumption that the
75 DSP, eg. Android HAL or PulseAudio sinks. By construction, regular

216 So we need to pass this to DSP. This metadata is extracted from ID3/MP4 headers
218 interface to pass this information to the DSP. Also DSP and userspace needs to

233 This is called when end of file is reached. The userspace can inform DSP that
234 EOF is reached and now DSP can start skipping padding delay. Also next write

249 - DSP switches to second track
290 coupling between the DSP and the host stack, limiting power savings.
