Allpassphase File

The phase response of a stable, causal all-pass filter is strictly . This means that as frequency increases, the phase angle continuously drops.

), keeping the gain constant while driving a frequency-dependent phase shift. Phase Response and Group Delay

Output: [ y[n] = a x[n] + x[n-1] - a y[n-1] ] The phase response of a stable, causal all-pass

Every allpass filter has a center or "turnover" frequency. At this specific frequency, the phase shift is exactly half of the filter's total phase shift capability (typically shifted by -90 or -180 degrees).

In the world of audio processing, we often focus on filters that change the volume of certain frequencies—like the bass boost on a stereo or a high-cut filter on a synthesizer. However, there is a specialized tool that leaves the volume completely untouched while radically altering the timing of the signal: the . Share public link For more information on the

Next time you’re struggling with a muddy mix or a hollow low end, stop boosting and cutting. Start rotating.
