WAV and AIF options

When you save in WAV or AIF format, the Save As Options dialog box appears. This dialog box provides a compact group of settings that you can quickly optimize.

General options

File Type
Indicates the file format.

Range
Specifies whether to save the entire file or the currently selected range.

Add To Files Panel
Adds the saved file to the Files panel.

Audio options

Sample Rate
Sets the rate at which audio is digitally sampled. Higher sampling rates support a wider frequency range, increasing audio quality and file size. To determine the proper setting for common output types, see Understanding sample rate.
Note: Though you can work with any sample rate in Soundbooth, your sound card may not be capable of playing all rates properly. To determine supported sample rates, consult the documentation for the card.

Sample Type
Sets the audio bit depth. Higher bit depths provide more dynamic range and reduce distortion, though they increase file size and processing time. To determine the proper setting for common output types, see Understanding bit depth.

Channels
Specifies whether the saved file contains one mono channel, two stereo channels, or six (5.1) surround channels. You can save to an equal or lesser number of channels. (For example, you can save a stereo file to mono, but not a mono file to stereo.)
