Sound Level Meter Peak Reset

Controls: Options >> Sound Level Meter >> Reset
Macro: SPLreset

The Sound Level Meter has continuous peak hold: It always retains peak values since the last Reset, and allows you to view them at any time.

Reset is a momentary button that clears both the Peak and PeakTC maxmimum values for all Sound Level Meter Channels. It also resets the Response Time internal states to cause an immediate total decay to zero.


Macro Notes:

SPLreset= resets the held SPL values and Response states. Any value given in the SPLreset= command is ignored.
