Creating MPEG-1 Output Files
• Bit Rate pop-up menu: Choose the bit rate to use for the output audio. Choices are
64 kbps, 128 kbps, 192 kbps, 224 kbps, and 384 kbps. Higher bit rates produce higher
quality audio, but they also produce larger output files.
Note: The 224 kbps and 384 kbps settings are not available when Channels is set to
Mono.
