How to add a flanger
1. Drop an audio file you already have. A video is refused here. 2. Leave light, or pick medium or deep. 3. Press “Add flanger” and download the same file type.
GustKit runs the FFmpeg flanger filter. Light uses a delay of 0 ms, a depth of 2 ms, no regeneration, a mix of 50 and a speed of 0.3 Hz. Medium uses 1 ms, 4 ms, 15, 71 and 0.5 Hz. Deep uses 2 ms, 6 ms, 35, 85 and 0.8 Hz. MP3, WAV, M4A, OGG and FLAC keep their type. The clock time stays about the same.
A sweeping delay, not a tremolo
Audio tremolo raises and lowers the volume on a pulse. Audio chorus mixes extra voices with a moving delay. Reverb adds short room reflections. This page mixes one short delay that sweeps. It does not change the pitch on purpose. A video belongs on the video pages.
The audio stays in this tab
FFmpeg runs in this browser. GustKit does not fetch audio from a link. Close the tab and the file is gone. Audio up to the limit shown next to the button.
How to check the flanger
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.
Audio tremolo pulses the volume. This page runs the FFmpeg flanger filter and keeps the file type. A short delay sweeps. Nothing is uploaded.
