Sample Rate

The project sample rate determines the number of samples per second Soundtrack Pro
uses for audio playback and export. When you add audio files to your project, their
sample rate is matched (upsampled or downsampled) on the fly to the project sample
rate. The available sample rates are 32 kHz, 44.1 kHz, 48 kHz, 88.2 kHz, and 96 kHz. The
default is 44.1 kHz, which is the standard for CD-quality audio recording.

Note: Digital video projects, including video for DVD, often use a 48 kHz sample rate.
When creating a score for a video, be sure you save and export your project at the
same sample rate the final video project will use.

To set the sample rate:

m

Choose the sample rate from the Sample Rate pop-up menu.

Note: If you open your project on a computer that cannot support the project sample
rate, the project is resampled to the nearest rate the hardware supports for playback.
When you export your project, it is exported at the project sample rate, regardless of
hardware limitations. For more information on hardware sample rates, see Chapter 1,
