class compress :?attack:float -> ?release:float -> ?threshold:float -> ?ratio:float -> ?knee:float -> ?rms_window:float -> ?gain:float -> int -> int ->object..end
Hardknee compressor with RMS look-ahead envelope calculation and
adjustable attack/decay. Given parameters are attack and release in
seconds, ratio n means n:1 compression, threshold and knee in dB,
and rms_window in second is the duration for RMS acquisition. gain is
an additional pre-gain.
