What makes a song “slowed + reverb”?
The sound comes from playing audio more slowly, like turning down the speed of a record. Tempo and pitch fall together. That darker, stretched character is the point — it is not tempo-preserving time stretch.
Reverb adds reflections after the direct sound. This maker uses a real convolution response, so the tail behaves like a room or plate instead of a simple echo.

Four useful starting points
Slowed + reverb
Start around 0.85× with a large hall and 35% reverb. Lower the mix if vocals lose clarity.
Daycore
Daycore is essentially slowed-down audio. Use Slowed Only, then add a small amount of reverb only if the track needs space.
Sped up
Try 1.15× to 1.25×. Faster is not always better; keep transients clear and stop before vocals become harsh.
Nightcore
Nightcore is sped up and brighter because the pitch rises with the speed. The 1.30× preset adds a light plate reverb.
Use audio responsibly
Make versions of your own tracks or music you have rights to. Changing speed or adding reverb does not give you permission to distribute someone else’s recording.
Slowed + Reverb FAQ
Does slowing a song lower its pitch?
Yes. This tool changes playback rate, so tempo and pitch move together. At 0.85× the song becomes slower and lower, which creates the familiar warped sound.
What is a good slowed + reverb setting?
Start with 0.85× speed, the Large Hall space, and 35% reverb. Then reduce the mix for dense songs or raise it for sparse, atmospheric music.
Is daycore the same as slowed music?
In practical terms, yes. Daycore usually means a track slowed down so its pitch also drops. Choose Slowed Only for the cleanest starting point.
What makes nightcore different from sped-up audio?
Nightcore is a sped-up style where the raised pitch and bright energy are central to the sound. The Nightcore preset starts at 1.30× with a light plate reverb.
Are my files uploaded?
No. Decoding, preview, reverb, rendering, and download preparation happen in your browser. Your file never leaves your device.
Can I download MP3 and WAV?
Yes. Render once, then download a 320 kbps MP3 or a lossless WAV. There is no signup and no watermark.
