AudioSuite Processing
Preferences
Before you begin using AudioSuite plug-ins, use
the Preferences dialog (Setups > Preferences >
Processing) to configure default AudioSuite op-
tions according to your needs. These options in-
clude the default dither setting, a dither on/off
checkbox, and the AudioSuite buffer size op-
tion.
AudioSuite Dither When selected, dither is ap-
plied during certain AudioSuite processes (such
as Normalize and Gain), using the dither algo-
rithm selected in the Dither Plug-In pop-up
menu. Dither is most useful when working with
low-level files that contain a fade in or fade out.
Dither Plug-in AudioSuite plug-ins always create
files that inherit the session’s bit depth. With
the Dither Plug-In pop-up menu you can choose
the dither algorithm used for dithering higher-
bit source files during AudioSuite processing.
Edit Settings Accesses options for the currently
selected Default Dither plug-in. In the case of
the Digidesign Dither plug-in, this lets you to
turn noise shaping on or off.
Bit Depth Selects the default bit depth used by
the dither function during AudioSuite process-
ing. Bit depth can be set to 16-, 18-, 20-, or 24-
bit.
AudioSuite Buffer Size Selects the size of
Pro Tools memory buffer for processing and pre-
viewing AudioSuite plug-ins. Choices are Mini,
Small, Medium, Large, or Jumbo. In general,
choosing a smaller buffer speeds up AudioSuite
previewing functions. Choosing a larger buffer
speeds up AudioSuite processing of audio files.
To configure the AudioSuite Buffer Size:
1 Choose Setups > Preferences.
2 Click Processing.
3 Select an AudioSuite Buffer Size.
Though the default setting will work well for
most situations, you may want to set the buffer
according to your current task. Before you audi-
tion an AudioSuite plug-in, set this buffer to
Mini or Small. Then, when you are ready to pro-
cess a file, reset it to Large or Jumbo.
4 Click Done.
