This option lets you save to any of several sample rates. Choices are dependent on your Pro Tools system and audio interfaces. Options can include sample rates from 8 kHz to 192 kHz, including sample rates with Pull Up and Pull Down options.
If you choose a sample rate that differs from the original sample rate of the session, the conversion options become available. You can configure the conversion quality, and schedule conversion to occur during, or after, the bounce. See
Sample Rate Conversion Quality for more information.
The following are the more common sample rates, and their applications. Higher sample rates provide better audio fidelity for recording and playback, and also for processing with dynamics, dither (with noise shaping), and analog emulation plug-ins.
This is a supported sample rate for some audio DVDs, and provides the highest quality audio fidelity with compatible audio interfaces (such as the 192 I/O).
You may want to work at a sample rate of 176.4 kHz if the final delivery will be at 44.1 kHz (such as compact disc). This will provide a slightly faster sample rate conversion to 44.1 kHz than from 192 kHz.
This is a supported sample rate for DVD audio and provides high-quality audio fidelity with compatible audio interfaces (such as the 192 I/O, 96 I/O, 96i I/O, 003, and Digi 002).
You may want to work at a sample rate of 88.2 kHz if the final delivery will be at 44.1 kHz (such as compact disc). This will provide a slightly faster sample rate conversion to 44.1 kHz than from 96 kHz.
This is a standard sample rate for Professional and DVD video, as well as some broadcast and recording label archiving, and is supported by DA-88/98, DAT, and ADAT decks.
This is the standard sample rate for compact discs (CD), and is supported by DA-88/98, DAT, and ADAT decks.
For a custom sample rate, click in the sample rate window and manually enter in a value from 4,000 to 200,200 samples.
All available sample rates support pull up and pull down rates, or other specialized rates.
