3. Select the Audio tab.
Note: To use a newly created preset (See Creating New Presets).
4. Check (optionally) the Audio Enabled checkbox. When checked, the audio for your
broadcast is included. When unchecked, audio is absent from your broadcast. This
is the preferred method of producing video-only broadcasts because the presence
of silent audio uses bandwidth.
5. Select the encoder to use.
6. Click Options to view and/or set the encoder options. Many, but not all encoders
have options that are specific to the encoder.
Note: If the Options button is greyed-out, no options are available.
7. Select the audio bit rate from the Rate menu. The higher the value you choose, the
better the quality, but more bandwidth is required.
8. Select Bits Per Sample. This is how much data each sample of audio uses. The
higher the value, the better the quality, but more bandwidth is required.
9. Select the number of channels: Mono or Stereo. Mono uses less bandwidth than
stereo, but stereo is more pleasing to the listener.
10. Click Save to save your settings.
