The DRE algorithm does not support all sampling rates and all channel combinations. Table 2-12 shows the sample rates and the corresponding number of channels supported at that sample rate by the DRE algorithm. For sample rates from 16 or 14.7 kHz to 48 or 44.1 kHz, the DRE algorithm supports all four analog channels. At a 96 or 88.2 kHz sample rate, the DRE algorithm only supports a maximum of two channels. At a 192 or 176.4 kHz sample rate, DRE is restricted to just one channel.
