7.3 Supported Codec
Following table shows the supported codec and suggested sample rate and corresponding bit rate. The Bit Rate
of NuOne, NuLite, and NuSound could be configurable. For example, using 8K sample rate, the bit rate could be
8Kbps (1bit per sample) or 12Kbps (1.5 bit per sample) or 16Kbps (2 bit per sample). Details please refer to
document in SDS.
