The
Sample rate
defines the number of times per second the sound is sampled. A higher sample rate will provide better audio
quality, but also requires a greater bandwidth.
Set the required
Bit rate
depending on the selected encoding. A higher bit rate will give better audio quality. A lower bit rate
may have latency or delay, but will require less bandwidth.
