FS#10449 - Compressor DSP

This patch is a proof-of-concept attempt at reducing gain of samples on the fly using an tanh algorithm to eliminate clipping. The signal is pre-amplified to bring up low level information and then everything above -6dB is increasingly reduced to bring the signal under the clipping limit. This has the effect of reducing dynamic range. So far, it’s not been optimized for speed or anything else; this is just to see if it works.

A different concept was used for the dynamic range compressor DSP.
