Make the dreamy slowed + reverb edit of any song — adjustable speed, reverb mix, and tail length, with live preview. Free, no account, no upload.
Slowed + reverb recreates the dreamy, washed-out edit all over TikTok and YouTube. It slows the track down and mixes in a synthetic reverb, and because slowing playback also lowers the pitch — like a record at a slower speed — you get that signature detuned, hazy feel. You control the speed, the reverb mix, and how long the reverb tail rings out, all with a live preview.
Most edits sit between 80% and 90% speed with a 2–3 second reverb tail; push the tail longer for a more ambient, distant sound. The pitch drop is intentional here — if instead you want to slow a track down while keeping the original pitch, the speed changer does that with time-stretching. Background on pitch and speed: how to pitch shift without ruining vocals.
Two things happen at once: the track is played back slower, and a reverb is mixed in. Slowing the playback also lowers the pitch — that slightly detuned, dreamy quality is the whole point of the 'slowed' sound, not a bug. The reverb, generated synthetically in code, adds the spacious, washed-out tail the style is known for. You control the speed, the reverb amount, and how long the reverb tail lasts, with a live preview.
Because playback speed and pitch are linked when you simply slow a recording down — like a record played at a slower RPM. That pitch drop is exactly the slowed aesthetic, so this tool leaves them linked on purpose. If instead you want to slow a track down while keeping the original pitch, the dedicated speed changer does that with time-stretching.
Most slowed + reverb edits sit between 80% and 90% speed — enough to feel slowed without dragging. For reverb, a mix of 30–45% with a tail of 2 to 3 seconds gives the classic dreamy wash; push the tail longer for a more ambient, distant feel. It's all live, so play the track and move the sliders until it feels right, then export.
Both change in step with the speed. At the default 85% the song plays about 2.8 semitones lower, at 80% about 3.9 semitones, and at the slider's minimum of 70% about 6.2 semitones, roughly half an octave. The length grows by the same ratio: a three-minute song at 85% runs about 3:32, plus the reverb tail you set, which is added to the end so it can fade out naturally.
Yes. Drag the reverb mix to 0% and you get a plain slowed version with no reverb at all. Leave the speed at 100% and only the reverb is applied, keeping the original tempo and pitch. If reverb on its own is what you're after, the audio reverb tool gives you more control, with presets from a small room to a cathedral plus pre-delay and brightness settings.
