Riff Looper & Slow-Downer
The transcriber’s best friend: open any audio file from your device, drag two markers around the riff or solo you’re chasing, and loop it as slow as 25% speed with the pitch preserved. Turn on train mode and every clean pass nudges the tempo back up toward full speed. Everything runs in your browser — the audio never leaves your device, and it works offline.
Slow it down, loop it, speed it back up. No uploads, no account, no install — just you and the lick until you own it.
Loop & slow down your audio
Loop: 0:00.0 – 0:00.0
Markers and speed are remembered per file on this device. Pitch is preserved as you slow down (on every modern browser).
Why practice with a looper?
Slowing a phrase down until every note is clean — then creeping the tempo back up — is how players have always learned solos. This tool does what desktop slow-downer apps do, free and in the browser: your recording, your loop, pitch intact. Pair it with the metronome’s speed trainer for the same ramp on your own playing, or study the lick library where every phrase ships with tab and audio.
