Signal Tools Leq(A) Metering Controls

Window

The Leq(A) window menu lets you choose the length of time the signal is measured before an average value is calculated. Settings range from 1 second to 2 minutes.

When the Leq(A) meter is in INF (infinite) mode it is constantly averaging the signal without a floating averaging window.

Reset

The Reset button lets you manually reset the start time of the Leq(A) measurement window.

Auto Reset

When enabled, causes the start time of the Leq(A) measurement window to be automatically reset whenever playback starts in Pro Tools.

Hold on Stop

When enabled, causes the Leq(A) measurement window timer to pause when playback stops, and resume when playback begins again.

In any of the Loop Transport modes, the measurement start time is automatically reset each time playback goes back to the beginning of the loop.
