Clip Indication
Because Pro Tools uses 64-bit floating point calculations for the mixer, there will never be any internal clipping in the mixer. However, it is possible to clip at the converters on your audio interface. It is also possible to clip when writing audio to disk in fixed point audio files (16‑bit or 24-bit files only, 32-bit floating point files will not clip).
Pro Tools meters provide infinite Clip Indication. If clipping occurs, the topmost LED will stay lit.
Clip indicators appear in plug-in, send, and track windows.
To clear a clip indicator:
Click anywhere on the meter.
To clear all clip indicators, do one of the following:
Option-click (Mac) or Alt-click (Windows) any meter.
Choose
Track > Clear All Clip Indicators.
Press Option+C (Mac) or Alt+C (Windows).
