4 Choose a sample rate, sample bit depth, and channel configuration from the
pop-up menus.
 Rate: Lower sample rates take less bandwidth but have lower quality. Make sure
your sample rate is compatible with the audio facility you’ll be handing the files off
to. Usually, you should use the sample rate specified in your sequence settings, which
should ideally be the sample rate of the original audio media files.
 96 kHz: This is a high-resolution sample rate that can be easily converted to
48 kHz.
 88.2 kHz: This is a high-resolution sample rate that can be easily converted to
44.1 kHz audio files.
 48 kHz: DV formats and many professional video formats use this sample rate.
 44.1 kHz: This is the sample rate of music CDs and some DAT tapes.
 32 kHz: This corresponds to a consumer sample rate option on DV camcorders.
Unless you have a special reason, avoid this sample rate for audio export.
 Depth: Choose the bit depth used for each sample.
 16-bit: This is the bit depth of DV, DVCAM, and DVCPRO, as well as of music CDs.
If all of your original audio media is 16-bit, and you aren’t routing multiple audio
tracks to the same audio output, choose this option.
 24-bit: A high-resolution bit depth compatible with many third-party capture
cards and external audio interfaces. Choose this option to preserve the highest
possible quality when exporting your files, especially when some of your audio
files are 24-bit, or when you are mixing multiple audio channels together by
routing them to the same output channel.
 Configuration: Choose whether to export a single stereo AIFF file or multiple
AIFF files.
 Channel Grouped: Exports multiple stereo or mono AIFF files based on your
sequence’s audio output groupings.
 Stereo Mixed: Outputs a single stereo AIFF file based on your sequence’s stereo
downmix settings.
5 When you’re ready to export, click Save.
Note: All audio that requires rendering is automatically rendered with a render quality
of High, regardless of the render quality setting.
