About the Sound Settings Dialog
You use the Sound Settings dialog to change your audio compression settings for either
the QuickTime or AIFF output format. To open this dialog, click the Audio Settings button
in the QuickTime Movie or AIFF Encoder pane.
If a particular audio setting cannot be changed, it remains dimmed. Most audio codecs
allow you to make additional settings. If this is the case, various buttons and controls
become available. Click them to make additional settings.

checkbox
The Sound Settings dialog contains the following items, with various choices for each,
depending on the audio codec you choose in the Format pop-up menu.
• Format: Choose the audio codec you want to add to your setting.
• Channels: Choose the type of channel output, such as mono, stereo, or some type of
multichannel output, depending on the codec.
• Rate: Choose the sample rate you want to use for your media file. The higher the sample
rate, the higher the audio quality, but the larger the file. Downloading a larger file takes
longer and requires more bandwidth.
• Options: This checkbox remains dimmed unless the codec you selected from the Format
pop-up menu offers options. It is recommended that you contact the manufacturers
of these codecs directly for more information about the additional options they offer.
QuickTime Audio Sample Sizes and Rates
If you have the disk space and bandwidth, it is best to leave your audio uncompressed.
Uncompressed audio normally uses 8-bit (phone quality) or 16-bit (CD quality) samples.
Compressor supports up to 64 bits per sample floating point and a maximum sample
rate of 192 kHz.
