Amazing Slow Downer has been a go-to practice tool for musicians for over two decades. It lets you slow down audio, change pitch, and loop sections — genuinely useful features for learning music. But at $50+ for the desktop version (and recurring costs on mobile), many musicians — especially beginners and students — are priced out.
That's why we built Music Slow Downer: a completely free, browser-based alternative that matches — and in some areas surpasses — everything Amazing Slow Downer offers.

Where Music Slow Downer Goes Further
1. Loop Export
Set an A/B loop, dial in your speed and pitch, and hit ⬇ Export Loop. You'll get a studio-quality WAV file of that exact section, rendered at your chosen settings. Pop it on your phone, burn it to a practice CD, or drop it into your DAW. Amazing Slow Downer can't do this.
2. Frequency Isolation Presets
Need to hear just the bass line? The vocal melody? Switch between six instrument presets — Bass, Guitar, Vocals, Drums, Keys, Highs — or dial in your own low-cut and high-cut frequencies manually. This makes it dramatically easier to pick out the part you're learning.
3. Browser Tab Recording
Practising along to a lesson on a video site or a track on a streaming platform? Click 🎵 Record Tab Audio, select the tab, and the audio is captured directly. No need to download files first — just record, stop, and practice immediately.
4. No Installation, No Account
Open your browser, load a file, and start practising. There's no installer, no sign-up form, no subscription. Your audio stays on your machine — nothing is uploaded to a server.
Who Is This For?
- Beginner musicians who want to slow songs down and learn by ear
- Students on a budget who can't justify $50 on practice software
- Guitar, bass, piano, drums, violin players — any instrument
- Music teachers who want to recommend a free tool to students
- Transcribers picking apart complex arrangements
What About Other Alternatives?
There are a few other tools musicians sometimes try:
- Audacity — powerful audio editor, but slow-down workflows are clunky and there's no real-time pitch-preserved playback loop
- Transcribe! — another paid tool ($39), desktop only
- YouTube playback speed — limited to fixed speeds (0.25x, 0.5x, 0.75x, 1x), no pitch shift, no looping, no export
- Anytune — iOS/macOS only, free tier is very limited
Music Slow Downer is the only option that's free, works on every platform, and includes tempo control, pitch shifting, A/B looping, frequency isolation, tab recording, and loop export — all in one place.
💡 Quick Start
Getting started takes about 10 seconds:
- Open the Music Slow Downer
- Drop in an audio file (or record from a browser tab)
- Drag the speed slider to slow things down
- Set A and B markers to loop hard sections
