Critical band equalization and compression

The multiband filter BARK takes the approach to match the reception
characteristic of the final destination of all sound: the ear. The ear
behaves as if it contains a bank of filters, each filter passing
frequencies within the critical band. Two tones separated by more than a
critical bandwidth are received by the ear independently. For this reason
BARK contains a filter bank with 27 bandpass filters matching the critical
bandwidth.

In fact, the human ear have also its own built in compression system which
are based on the critical bands. Consequently BARK incorporates an
independent compression algorithm for each of it?s 27 bands.

Features:
