Audio level
Audio level is a Drivers effect.
What it does
Section titled “What it does”Returns the loudness at the current frame of the sound the Source row picks. It has four sockets: Amplitude, the level of the whole sound, Low, the level of the bottom end, Peak, the loudest single sample, and High, the level of the top end.
The level is measured over a short stretch of time centred on the frame. A layer or clip that has been deleted reads 0. An Audio level saved before the Source row existed and set to a layer reads that layer’s file before its volume.
