Comments

Allpass is a special case of Comb. In the case of an allpass filter, the feed-forward and feedback gains are mirror images, that is, feed_forward = -feedback.. Allpass filters have a flat frequency response, although they have phase responses that vary with frequency.

Issues

Currently only accepts a maximum delay of 0.25 seconds. For greater delays, use the Delay transform.
