Phaser
Sweep six all-pass stages through the sound and blend them with the original.
Every parameter, explained
Cycle time
200 ms to 10000 ms · Default 4000 msThe duration of the sweeping cycle. Longer values create gradual movement.
Sweep depth
0% to 100% · Default 70%The frequency range covered by the six moving all-pass stages. Higher values make the sweep more pronounced.
Mix
0% to 100% · Default 50%The balance of original and phase-shifted audio. The characteristic notches are strongest with both present, around 50%.
A good place to start
Try the sample or upload a short recording. Apply the defaults, compare Original and Result, then adjust one parameter at a time. Revisions on this page start from your original recording.
What to listen for
The moving phase shifts create notches when mixed with the dry signal. A 50% mix gives the clearest sweeping character.
Compare a quiet passage and a busy passage at a comfortable listening volume. The player volume changes playback only; it does not change the downloaded audio.
Can I combine this with other effects?
Yes. Open the combination studio and choose this effect along with any others. Effects run in the displayed order, and completed stages are reused. Changing or removing an earlier effect rebuilds the affected stages.
Once processing finishes, compare the result and download MP3 or WAV. MP3 encoding runs locally and does not apply the effects again.
