Interleave Peak/VU Toggles interleaved or stacked display of VU/PPM meters with the corresponding channel meters.
Routing channels to hardware outputs
You can change channel assignments from the Audio tab in the Preferences dialog or the Channel Meters window. Changing the setting
in either location updates your preferences and affects all open data windows.
To change a channel’s output device using the Channel Meters window, click the channel number and choose a new output port from

For more information on changing channel assignments in the Preferences dialog, see Audio tab on page 322.
Using the VU/PPM meters
You can display volume unit (VU) and peak program (PPM) meters in the Channel Meters and Hardware Meters windows to help you
determine the perceived loudness of your audio signal (peak program meters provide faster response times to volume increases than
VU meters). For more information on channel meters, see Using the channel meters on page 44. For more information on hardware meters, see
Using the hardware meters on page 111.
VU/PPM meters are especially helpful when you’re mastering. Comparing two audio files’ VU/PPM readings will help take the guesswork
out of matching levels.
Right-click the Channel Meters or Hardware Meters window and choose Show VU/PPM from the shortcut menu to toggle the display of
the VU/PPM meters.
VU/PPM readings should fall near the 0 (or reference) mark. 0 VU is merely a reference level, and your signal may exceed 0 VU. To prevent
clipping, keep an eye on your peak meters. Peak levels should never exceed 0 dB. You can use the Status tab in the Preferences dialog to
calibrate the VU/PPM meters to their associated levels on the peak meters and adjust the VU meters’ sensitivity. For more information, see
Status tab on page 320.
