The free music practice tool that lets you loop any section, slow down without changing pitch, and train at progressively faster speeds. Works with any instrument.
No account needed. Drop a file and go.
No bloat. Just the tools that actually help you improve.
Click and drag on the waveform to select any section. It repeats seamlessly until you nail it. Fine-tune boundaries with ±0.1 second precision.
Reduce speed from 0.1× to 2× while keeping the original pitch. Hear every note clearly, even in the fastest passages.
Set a start speed, target speed, and step size. RepShed automatically increases tempo after each set of loops — like interval training for musicians.
See your entire track as a scrollable waveform with a minimap. Zoom in for precision, zoom out for overview. Navigate visually.
Hands on your instrument, not your mouse. Space to play, brackets to set loop points, arrows to seek. Full control without leaving position.
All processing happens in your browser with the Web Audio API. No uploads, no servers, no accounts, no tracking. Your music stays yours.

Loop that solo, slow it to 50%, and learn it note by note. Speed Trainer gets you back to full tempo gradually.
Isolate tricky passages in classical pieces or jazz solos. Fine-tune loop boundaries to exact beat positions.
Loop fills and breaks, slow them down to hear every ghost note. Practice along at comfortable speeds.

It's like interval training for musicians. Set a start speed (e.g. 0.5×), a target (e.g. 1.0×), and a step (e.g. 0.05×). RepShed auto-increases the tempo after a set number of loops, building your speed gradually without overwhelming you.
You can adjust loop start and end points with ±0.1 second precision using the fine-tune controls. You can also type exact timestamps.
No. There's no account system. Just open the page and start practicing. Your audio never touches a server.
