# Slowed + Reverb Maker > To make a song slowed and reverb, lower its playback speed (usually to 80–90%) — which also lowers the pitch — and add a long, washy reverb. The tool above does both in your browser: load an MP3, WAV, M4A or OGG file, choose Slowed + reverb (85% speed, 45% reverb), Extra slowed, Sped up or Nightcore (125%), adjust the sliders while it plays, then download a WAV. Processing happens on your device with Web Audio — the file is never uploaded. Use it on music you have the rights to; for an original track to slow down, Kenerate's Music Studio can make one.

Nightcore is the opposite — faster and higher. ### How the tool works Under the hood: - Speed — changes playback rate, so pitch follows (like a record). - Reverb — a convolution reverb with a generated 3-second tail. - Export — rendered offline, sample-accurate, as a WAV.

A: Load the file into the tool above, choose Slowed + reverb (about 85% speed with a long reverb), adjust to taste, and download the WAV. Q: Is the slowed reverb maker free? A: Yes — it runs in your browser with no sign-up, and the WAV download is free. Q: Is my file uploaded? A: No. Everything happens on your device with the Web Audio API; the file never leaves your browser. Q: How do I make nightcore? A: Choose the Nightcore preset (about 125% speed) — speeding up raises the pitch, which is the nightcore sound. Q: Why does slowing down lower the pitch? A: The tool changes playback speed, like a turntable, so pitch moves with speed — that's the characteristic slowed sound. Q: What formats work? A: Most MP3, WAV, M4A and OGG files; the download is a WAV. Q: Can I upload slowed versions of other artists' songs? A: Only if you have the rights. For something you can share freely, make an original track in the Music Studio and slow that down. ## Related pages - AI lofi generator: https://kenerateai.com/ai-lofi-generator - Phonk maker: https://kenerateai.com/phonk-maker - Click track generator: https://kenerateai.com/click-track-generator - AI song extender: https://kenerateai.com/ai-song-extender ## Sources - MDN — ConvolverNode: https://developer.mozilla.org/en-US/docs/Web/API/ConvolverNode
