The only option is the codecflavor.MPEG-3 audio file format. The only option is the bit rate (in bps).Note: Stereo or Mono is specified automatically: bit rates below64 000 are mono, 80 000 and above are stereo. If the inputis mono, then the output is also mono.Make-up of the Enhanced AAC Plus codecBit rateUse this option to specify the bit-rate value for an audio stream in bits persecond (bps). Different bit-rate ranges are available for different audioencoders.Note: This option is not available for the RealAudio encoder.Use joint stereo (AAC audio encoder only)Joint stereo coding removes redundancies between the left and right audiochannels of stereo sources. Select this option to encode channel redundanciesand differences separately. Using this setting can reduce the bit rate by asmuch as half, but it also might introduce some artifacts. Clear the Use jointstereo check box if you want the redundant portions to be encoded twice.36
