From Rane pro audio reference:
"From our example, for every input increase of 1.6 dB above the hinge point, the output only increases 1 dB, and for every input decrease of 1.6 dB below the hinge point, the output only decreases 1 dB."
http://www.rane.com/par-c.htmlAuthor is describing the earliest compressors which use a hinge point, instead of a threshold. I'd like to hear that in action. Are there any modern devices that work in this way?
