Slowed and Reverb Generator

It is a remix of a song that plays slower and lower, with reverb added so it sounds distant and dreamy. Slowing the song lowers its pitch, like a record played too slowly, and the reverb fills the gaps with a soft echo. The style draws on chopped and screwed hip-hop and on vaporwave, and became popular on YouTube and TikTok.

Open the song in the generator above. It starts at 0.85x speed with 40% reverb and the pitch lowered to match, the classic slowed + reverb sound. Press play, move Speed and Reverb until it sounds right, then choose MP3 or WAV and press Save.

Most slowed + reverb uses 0.80x to 0.90x speed with 30% to 50% reverb, and 0.85x with 40% is the classic choice. For songs with a lot of words, 20% to 30% reverb keeps the lyrics clear. For instrumental, ambient or late-night edits, try 0.75x with 60% or more. If the voice sounds too deep, move Speed closer to 1.00x.

Playing a recording slower makes every sound wave repeat less often, which we hear as a lower pitch, like a record or tape running too slowly. Slowed + reverb keeps that effect on purpose. With Follow speed on, the pitch drops exactly as much as it would on a slower record: 2.81 semitones at 0.85x and a full octave at 0.50x.

Yes. Turn off Follow speed and set Pitch to 0, and the song plays slower in its original key, with the reverb still on. With Follow speed off you can choose any pitch from −12 to +12 semitones.

Slowing a song stretches it: the length is divided by the speed, so a 4:00 song at 0.85x lasts 4:42. The reverb then rings out for about 3 seconds after the last note, so the saved file is 4:45. The length next to the original already includes that fade.

Nightcore is the opposite: the song plays faster and higher, and the Nightcore Maker on this site makes it. Daycore is a slowed and lowered version too, usually with little or no reverb, so Reverb at 0% to 10% gives that sound. Vaporwave is a genre of its own, built from slowed, looped samples of 1980s and 1990s pop, R&B and lounge music, and slowed + reverb borrows its hazy sound.

Changing the speed and adding reverb does not change who owns a song. A slowed version of someone else’s track is still their music, so TikTok and YouTube treat it like the original: it may be matched to the rights holder’s recording, which can mean the sound is muted, the video is blocked in some countries or the rights holder earns from it. Songs you made yourself, music you have a license for and tracks whose owners allow edits are the safest to post. Each platform explains its music rules in its help pages.

MP3, WAV, M4A, FLAC and OGG audio, plus common video files such as MP4, MOV and WebM, where the soundtrack is used. Each file can be up to 500 MB. You can save the result as MP3 at 320 kbps or as WAV, at the same sample rate as your file.

No. Your browser opens, slows down, adds the reverb and saves the song on your own device, and nothing is sent to a server. Reloading or closing the page clears it.
