Hi Ollie

I will answer both postings in one mail.

> Have you thought about how to realize the ratio/limiting behavior

The ratio is simply the modulation amount at the VCA.

> How do you like the sound of your compressor

I found, that it acts quite crude. It definitely requires a linear VCA
instead of a exponential. Also: If you put a passive highpass in the
analysis signal path, then the action becomes more musical.

I use it not often, but it is interesting if you split a signal with the
A121 in different frequency bands, and the different bands then are
handled by different compression ratios (VCA modulation amounts).

This is called a Ducker. Some commercial noise gates and also some
compressors can act as duckers (LA Audio did some).
