Allpassphase Guide

Consider a transient sound—a sharp click or a snare drum hit. This transient is composed of a wide spectrum of frequencies. If an allpass filter shifts the phase of the high frequencies relative to the low frequencies, those frequency components no longer align perfectly in time. The result? The peak amplitude of the transient is reduced, the waveform becomes asymmetrical, and the "punch" is softened—even though the frequency spectrum (the EQ) looks identical.

: Increase the number of filter stages to stack the filters, making the squishy phase effect dramatically more intense. ⚡ Best Creative Use Cases allpassphase
