Chapter 2: Hardware Interface Description Unlike basic audio mode, which provides predefined audio paths, the advanced audio mode provides full control over the C24 audio interface and its parameters, and differentiates between each type of audio sound. Table 2-11 describes the advanced mode audio programming features. These features are only a part of the complete advanced audio AT command set. Table 2-11: Advanced Mode Commands Command Description AT+MAPATH Sets the input device for voice, and the output devices for voice, DTMF tones, rings and alerts. AT+MAFEAT Enables and disables the speech processing algorithms - Echo suppression, noise suppression and sidetone. AT+MAVOL Sets the gain (amplification) level of the selected analog output device. AT+MMICG Sets the gain (amplification) level of the selected analog input device. AT+MADIGITAL Switches between analog and digital audio paths. Audio Programming Interface The C24 incorporates a unique audio programming interface, through AT commands, which controls the following audio features: • Audio Path - Defines the input and output devices for speech, DTMF tones, rings and alerts. • Audio Gain - Defines the amplification (gain) level for input and output audio devices. • Audio Algorithm - Defines the speech processing features for voice calls.
