Allpassphase [updated]
When the phase-shifted signal is mixed back with the dry signal, certain frequencies cancel each other out (destructive interference), creating moving notches in the audio spectrum. 2. Phase Alignment in Mixing and Live Sound
A phaser effect creates a "swirling" sound by mixing the original signal with an allpass-filtered version. Because the allpass filter shifts the phase of specific frequencies, summing the wet (shifted) and dry (original) signals causes frequency cancellation (notches) at those specific frequencies, which move over time to create the sweeping sound.

Essential for creating "Phaser" effects. When a phase-shifted signal is mixed with the original "dry" signal, it creates notches in the frequency response. Best Use Cases
While the magnitude remains unchanged, the phase response does not. An allpass filter introduces a frequency-dependent time delay. This delay causes a phase shift that varies across the frequency spectrum. When the phase-shifted signal is mixed back with
An all-pass filter is a type of electronic filter that allows all frequencies to pass through with minimal attenuation, while modifying the phase response of the signal. Unlike other types of filters, such as low-pass or high-pass filters, which attenuate certain frequency ranges, an all-pass filter affects the phase of the signal without changing its amplitude.
