7 Sample Rate Support

The DRE/DRC algorithm does not support all sampling rates and all channel combinations. Table 7-1 shows the sample rates and the corresponding number of channels supported at that sample rate by the DRE/DRC algorithm. For sample rates from 16 or 14.7 kHz to 96 or 88.2 kHz, the DRE/DRC algorithm supports all two analog channels. At a 192 or 176.4 kHz sample rate, DRE/DRC is restricted to just one channel.
