The sample rate of the input signal. It doesn't pay to increase the
encoding sample rate above that of the input sample rate.
For the lowest audio bit rates it's often recommendable to use the
lowest sample rate for best quality.

(kbit/s).
Settings for the compressed bit rate are available from 56 to 640
kbit/s. Increasing the number in this field increases the audio
bandwidth at the encoder, improving the quality of the audio
transmitted by the encoder. The default is 192 kbit/s. Use the
following data rate ranges for the selected audio mode.
Mode
Stereo 2/0
Dual Mono 1+1
