15. Select the number of channels: Mono or Stereo. Mono uses less bandwidth than
stereo, but stereo is more pleasing to the listener.
16. Select the audio bit rate, in Kbits (1000 bits) per second, from the Target Bit Rate
menu. This is the target bit rate of your audio. Higher numbers provide better
quality. The connection speed of your audience is a significant factor in
determining your target bit rate. The encoder compresses the audio to
approximate this target. However, at different times during your broadcast the bit
rate may be higher lower than the target rate. The total broadcast bit rate is a
function of video bit rate plus audio bit rate.
17. Select the audio sample rate, in kHz (1000 Hz) per second, from the Sample Rate
menu. This value specifies how many thousands of times per second to sample the
audio in the broadcast. Higher values provide better quality sound, but at greater
bandwidth.
