C24 Module Hardware Description

December 15, 2008

Figure 2-22

describes the audio programming interface options, which are defined by AT

commands.

Figure 2-22: Audio Programming Interface

Audio Algorithms

The C24 audio interface features advanced speech processing algorithms for echo suppression,
noise suppression and side-tone feedback

Enabling or disabling the algorithms can be configured separately for each audio path and
operating mode through the AT command interface.

The C24 also supports EVRC, EVRC-B and 13K speech coding algorithms, which are used by
the CDMA network. These algorithms are configured and operated by the CDMA network
provider.

Table 2-12

gives the speech processing features.
