I'm using ALSA API (alsa-lib 1.0.25) for writing an audio application
for an embedded product.
This is my understanding of the sw_params configuration api: (Can
someone please confirm if the explanation is correct?)
snd_pcm_sw_params_set_start_threshold -- sets the minimum no. of
frames before which playback will not start.
snd_pcm_sw_params_stop_threshold -- sets the minimum no. of frames
when the playback stops (not completely clear)
snd_pcm_sw_params_set_silence_threshold -- sets the no. of frames for
inserting silence (equal to set by set_silence_size) when frames is
less than the value set.
Any info will be of help.
