Bit Depth

This setting lets you select between four different bit-depths for the bounce conversion. Note that Bounce to Disk does not apply dither when converting during or after a bounce to a lower resolution. If you need to bounce to a lower resolution file, use a dither plug-in on a Master Fader track assigned to the bounce source path. This dithers the bounced file, before the Bounce to Disk conversion truncates the bounced file to the selected bit depth resolution. (See Using Dither.)

The following Bit Depth options are available:

8-Bit

This resolution is often used in multimedia applications. If the material you are working with is relatively simple, you can use the Pro Tools “Squeezer” feature for optimal results. See Use Squeezer for details.

16-Bit

This is the Compact Disc standard bit resolution.

If your session is 16-bit, you should still use a dither plug-in on the output mix, because all Pro Tools systems process audio internally at higher bit depths.

24-Bit

This setting provides the highest resolution that is compatible with most audio interfaces. It is useful when you want to create a final mix without losing any resolution (for example, if you are delivering a final mix that will be ready to master).

32-Bit Float

This setting provides the highest resolution for internal Pro Tools mixing and plug-in processing. It is useful when you want to export and re-import loops and sound effects into your Pro Tools session, or when you are exchanging files between Pro Tools sessions.

To set the resolution of the bounced file:

Select a bit depth from the Bit Depthselector.
