This patch adds to audio_stream.h inline functions: - audio_stream_align_frames_round_down() - audio_stream_align_frames_round_up() They are useful when an algorithm needs to process a number of frames that is smaller then data size than offered by module API. E.g. when volume component ramps the volume, the block with same gain is smaller than a normal processing period. Signed-off-by: Seppo Ingalsuo <seppo.ingalsuo@linux.intel.com>
This patch fixes an issue where processing smaller parts of the period can break the data align constraints. The frames count value from zc_get() function or from cd->vol_ramp_frames is rounded up to next align compatible frames count. The failure with align constraints appeared as glitches in audio with some 44.1 kHz family sample rates. Signed-off-by: Seppo Ingalsuo <seppo.ingalsuo@linux.intel.com>
