List of all members.

Detailed Description

Command: tone / chirp to play.

The audiodsp interface accepts commands to produce fixed-frequency tones or binary phase shift keyed(BPSK) chirps through /dev/dsp (which is assumed to be associated with a sound card to which a speaker is attached). The command subtype, which should be PLAYER_AUDIODSP_PLAY_TONE, PLAYER_AUDIODSP_PLAY_CHIRP, or PLAYER_AUDIODSP_REPLAY, determines what to do.
