Slowed + Reverb Editor

A slowed + reverb generator is an online audio tool that reduces a song's playback speed and adds a reverb (echo-like) effect. This creates a dreamy, atmospheric, often melancholic sound popular in lo-fi music, TikTok edits, and chill playlists. The effect originated from the chopped-and-screwed hip-hop subgenre and has since spread into vaporwave and ambient remix culture.

Nightcore is a music style where songs are sped up (typically 10-30% faster) and the pitch is raised, resulting in higher, more energetic vocals. It's popular in anime edits, gaming montages, and dance remixes. Use the speed control above 100% with the pitch link enabled to create nightcore versions.

Daycore is the opposite of nightcore — songs are slowed down and the pitch is lowered, creating a deeper, more relaxed sound. It's also called anti-nightcore or simply "slowed." Combined with reverb it becomes the classic "slowed + reverb" effect.

Chopped and screwed is a hip-hop subgenre pioneered by DJ Screw in Houston, Texas during the 1990s. Tracks are significantly slowed ("screwed") and sections are repeated or skipped ("chopped"). This editor lets you recreate similar atmospheric, slowed-down vibes — though full chopping requires manual section work in a DAW.

Upload your audio file (MP3, WAV, FLAC, M4A, or OGG), drop the speed slider below 100%, raise the reverb amount until the room sounds right, optionally boost the low end, then click Render & Save to download as WAV. Everything runs in your browser — no uploads to servers.

Yes — vaporwave often uses the same techniques (slowed playback, heavy reverb, occasional pitch drops). Try 70-80% speed with a generous reverb tail to land in the signature nostalgic, retro-futuristic aesthetic.

The trend traces back to DJ Screw's chopped-and-screwed movement in 1990s Houston hip-hop. It gained mainstream popularity in the 2010s through YouTube and exploded on TikTok in 2020-2021, where creators began posting slowed + reverb edits of pop, R&B, and hip-hop tracks for their atmospheric, emotional quality.

No — derivative works of copyrighted material require licensing. Use your own recordings, public-domain audio, or material you have a sync license for. Many TikTok/Reels uses fall under platform-level licensing arrangements; check your platform's rules.

Default export is 16-bit/44.1 kHz WAV. The paid plugins (RysUpVerb, RysUpShift) ship 24-bit and 32-bit float in your DAW for proper bus processing.

Most tools process audio entirely in your browser via the Web Audio API — your file never leaves your device. AI-powered tools (stem splitting, vocal removal) run on cloud GPUs and the input is deleted immediately after the job finishes.

Every tool accepts MP3, WAV, FLAC, M4A, and OGG up to 50 MB per file. Exports default to high-quality 16-bit WAV.

Yes — every tool is responsive and works in iOS Safari and Android Chrome. Some tools (like the virtual piano) are optimized for multi-touch.
