Gain reduction for tanh~?
Nov 17 2012 | 7:17 am
I'd like to make a fader that turns up tanh~'s input, while simultaneously turning down it's output. Currently I am just scaling down the maximum output using the scale object. Problem is the it gets too loud in the middle part of the range. I think if I applied
a inverse gaussian curve to the output, that would work, but I don't understand how to do that yet. Any ideas?

- Dec 03 2012 | 2:44 amHow did Wales do? Thanks for the thoughts and the patch, I think you are right about tanh~ sounding subjectively louder without actually being turned up. This is a little trickier than I thought, especially if it's "subjective" volume I'm attenuating. Another issue is using an audio source that is not at unity gain (like a live guitar loop), it may need a different volume curve.
