Hello. Does anyone know what the numbers represent in the editor window for the Phaseplant SHAPER effects module? Thanks.

I'm guessing it's a waveshaper and it's positive and negative from zero to digital full scale (probably at 64 bits fixed point). So each input sample level is graphed to an output sample level. Usually there's a way to turn off bipolar mode for waveshapers so you don't have to worry about matching the positive and negative values if you want symmetrical distortion.

This would be the same if the shaper was mapping any set of values to any other. In coding it's often much simpler to map all your values between 0 and 1. It makes for simpler math.

This helps. Just need to wrap my head around the graph since, as you mentioned, they display it as bipolar with no other option. Thanks for your reply.

In digital processing, samples are usually between -1 and 1 where both -1 and 1 correspond to 0dBFS.

So the numbers simple represent the value of the sample going into the shaper. Everything outside that range seems to get hard clipped.
