Stereo hard- and soft-knee signal compression algorithms
PAUs: 1
The stereo hard- and soft-knee compressors are very similar algorithms and provide identical parameters
and user interface. Both algorithms compress (reduce) the signal level when the signal exceeds a threshold.
The amount of compression is expressed as a ratio. The compression ratio is the inverse of the slope of the
compressor input/output characteristic. The amount of compression is based on the sum of the
magnitudes of the left and right channels. A compression ratio of 1:1 will have no effect on the signal. An
inÞnite ratio, will compress all signal levels above the threshold level to the threshold level (zero slope).
For ratios in between inÞnite and 1:1, increasing the input will increase the output, but by less than it
would if there was no compression. The threshold is expressed as a decibel level relative to digital full-
scale (dBFS) where 0 dBFS is digital full-scale and all other available values are negative.
