SLOWED + REVERB
The Vibe
Slowed and reverb is the viral TikTok / YouTube remix style that takes a song, slows its tempo, often pitches it down a few semitones, and layers heavy spacious reverb on top. The result feels dreamy, nostalgic and cinematic — perfect for moody edits, vlogs, study playlists and aesthetic content.
Speed · Pitch · Reverb
Our generator bundles the three effects you need: a speed slider (0.25x–4x), a pitch shifter (±12 semitones) and a real convolution reverb with Subtle → Cathedral presets. Stack them to recreate the classic slowed+reverb sound in seconds.
Privacy First
Your audio never leaves your device. All processing — time-stretch, pitch-shift and reverb — runs locally with the Web Audio API. No uploads, no accounts, no watermarks on the exported WAV.
Drop the tempo to classic slowed values like 0.85x or 0.75x to get that stretched, hazy feel — without turning vocals into a chipmunk.
Add real convolution reverb with Subtle, Room, Hall and Cathedral presets. Great for the spacious, wet, late-night vibe everyone loves.
Shift pitch ±12 semitones. Pitch down −2 / −3 for the signature moody edit sound, or up for nightcore-style variations.
Hear the slowed + reverb sound instantly while you drag sliders. No render wait, no guesswork — dial in the perfect vibe live.
Drop in MP3, WAV, FLAC, OGG, AAC or M4A. Any format your browser can decode works — no conversion required.
Render the full slowed, pitched and reverbed track to a high-quality WAV with an extra reverb tail baked into the end.
It's a tool that takes any audio file, slows its playback speed, optionally pitches it down, and applies reverb to create the iconic 'slowed + reverb' remix style popularized on TikTok and YouTube.

A classic starting point is Speed 0.85x, Pitch −2 semitones, Reverb 'Hall' (around 75%). Fine-tune from there based on the track.
We generate a stereo algorithmic impulse response and feed the audio through a ConvolverNode, then blend it against the dry signal using the Reverb slider.
Yes. By default the tool ties speed and pitch together (like a tape deck). To preserve pitch, pitch-shift up by the matching semitones when you slow down.
Yes. Enable the 'Loop Section' toggle and set start/end times to repeat a specific part — perfect for finding the best hook for an edit.
Yes. The exported WAV is rendered with the current speed, pitch, and reverb settings baked in, plus a 2.5-second reverb tail appended to the end.
Absolutely — the slowed + reverb aesthetic is one of the most popular audio styles on short-form video. Render to WAV and upload straight into your editor.
Yes. Many users turn pop, R&B, and anime OP tracks into slowed + reverb lo-fi versions for background / study playlists.
Yes. Instead of slowing down, set speed to 1.25x–1.5x and pitch up +3 to +5 semitones for a nightcore feel — with or without reverb.
The tool itself is free to use. Make sure you have the rights to remix and distribute any source audio you process.
