The All Pass Filter passes all frequencies at equal amplitude but shifts the phase of the signal. This is useful for building phaser effects and other phase-based processing.

Chain multiple All Pass Filters at different frequencies and mix the output with the dry signal to create phaser effects. Modulate the Pitch input with an LFO for the classic sweeping phaser sound.
