GustKit runs the FFmpeg aphaser filter. Light uses input gain 0.4, output gain 0.74, a delay of 1 ms, decay 0.2, speed 0.3 Hz and a triangular sweep. Medium uses 0.4, 0.74, 3 ms, 0.4, 0.5 Hz and a sine sweep. Deep uses 0.6, 0.85, 5 ms, 0.8, 1.2 Hz and a sine sweep. MP3, WAV, M4A, OGG and FLAC keep their type. The clock time stays about the same.

A phase sweep, not a flanger

Audio flanger mixes one short delay that moves. Audio tremolo raises and lowers the volume. Chorus adds extra voices. This page runs aphaser, which sweeps the phase of the sound. It does not change the pitch on purpose. A video belongs on the video pages.

The audio stays in this tab

How to check the phaser

1. Play the download next to the original. 2. Light should sweep a little. Deep should sweep harder. 3. If the file type changed, you opened a different page.
