Audio Cross Clipper is a dynamics block with two audio inputs and one audio output. The first input is tested against the Upper Clip (0 to 1) and Lower Clip (-1 to 0) thresholds: while it stays between them the second input passes through to the output, and when it crosses a threshold the output is held at that threshold value. Gain Out (-60 to +60 dB) sets the output level.
Each tick it reads the first input, compares it with the two clip limits, and either passes the second input or clamps the output to the exceeded limit, then applies the output gain. It processes one sample-frame per tick, in step with WaveWarp's sample-per-sample engine.
