Allpassphase ⟶ «EXCLUSIVE»

The is a unique tool that lives entirely in this second dimension. Unlike a low-pass or high-pass filter, an all-pass filter doesn't change the volume of a sound at all. Instead, it only manipulates the allpassphase —the timing relationship between different frequencies.

This shift is most dramatic near the filter’s cutoff frequency, where the "group delay" (the actual time delay felt by the signal) is at its peak. Conclusion allpassphase
