Mix your signal with delayed copies whose delay time is constantly moving, so the copies drift slightly in pitch and sound like several performances playing together.
Upload standard audio formats (MP3, WAV, FLAC, AAC, etc.) or listen to the test tone generator while adjusting Voices, Rate, Depth, Stereo Spread, and Mix.

Frequently Asked Questions
Chorus mixes your audio signal with delayed copies whose delay time is constantly moving. The copies drift slightly sharp and flat in pitch, creating a rich ensemble sound. You can load WAV, MP3, M4A, AAC, OGG, Opus, and FLAC files.
Chorus uses delay times around 12 ms without feedback, sounding like separate doubled voices. A flanger uses shorter sub-10 ms delays with feedback to create jet-like sweeping comb filtering.
1 voice gives subtle movement, 2 voices provides classic vocal/guitar chorus, and 3 voices produces a dense ensemble pad effect.
Stereo Spread offsets the modulation phase between left and right channels, making voices sweep in opposite directions to widen the stereo soundstage.
