Allpassphase 🎉

: The height of the wave, which determines how loud it is.

The all-pass filter, captured by the keyword "allpassphase," stands as one of the most elegant and versatile tools in signal processing. Its defining characteristic—constant magnitude response paired with flexible phase manipulation—enables applications ranging from audio phaser effects and loudspeaker alignment to optical dispersion compensation and digital communication equalization. allpassphase

Interestingly, while a standard low-pass or high-pass filter introduces a total phase shift of only 90° per pole, the reflected zero in an all-pass filter adds an extra 90° for every pole, doubling the total phase shift potential per stage. : The height of the wave, which determines how loud it is

This is the most common use case. Imagine you have a kick drum and a bass guitar playing the same note. Even if they are perfectly in time on the grid, the waveforms might be out of phase. This causes the low end to cancel out, making your mix sound thin and weak.

To understand how the plugin works, it is necessary to examine the mechanics of digital audio filters. Traditional equalizers (EQ) change both amplitude and phase: a low-pass filter cuts high-frequency volume while shifting the time arrival of the remaining frequencies.
