To customize sound settings for export:

- Choose "Movie to QuickTime Movie" from the Export pop-up menu.
- Click Options.
- In the Sound area of the Movie Settings dialog, click Settings and then choose your options:
Format: Choose the compressor (codec) you want to use for compressing sound. For general use and Internet delivery of music, MPEG-4 Audio (AAC) is recommended.
Channels: Choose between mono (1 channel) or stereo (2 channels).
Rate: Digitized sound is made up of sound samples. The more samples per second, the higher the sound quality. To maintain quality, music requires a higher sampling rate than spoken voice because music uses a wider range of frequencies. Audio CDs use a sampling rate of 44.1 kHz.
Render Settings: Choose the quality of the signal processing that will be used; higher quality settings take longer to process.
Other options: To see additional options specific to your chosen codec, if any, click the Options button. if it's available.
