¶ Allpass2
Category: 🔊 Audio
¶ Description
Second-order allpass filter. Passes the input signal through unchanged in amplitude but shifts its phase around a break frequency — the building block of phaser effects.
Chain several Allpass2 blocks and mix the result with the dry signal to build a classic phaser. The Frequency input sets the notch / break frequency, and the Radius controls how steep / resonant the phase shift is (typical values are slightly below 1).
