audiodsp [Interfaces] Detailed Description The audiodsp interface is used to control sound hardware, if equipped. Classes struct   player_audiodsp_data   Data.

The audiodsp interface reads the audio stream from /dev/dsp (which is assumed to be associated with a sound card connected to a microphone) and performs some analysis on it. Five frequency/amplitude pairs are then returned as data. typedef struct player_audiodsp_cmd player_audiodsp_cmd_t   Command. 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). typedef struct player_audiodsp_config player_audiodsp_config_t   Configuration request : Get/set audio properties. Configuration request: Get/set audio configuration. Request/reply packet for getting and setting the audio configuration.
