An Amazing Slow Downer Alternative

Slow down music without changing pitch and loop any section — in your browser, with YouTube built in. Shift the key of your own audio files too.

Updated October 2026

LoopTube is a free, web-based alternative to Amazing Slow Downer: it slows down MP3s, audio files and YouTube videos without changing the pitch and loops any section, and shifts the key of your audio files — entirely in your browser, without uploading your files to a server.

Amazing Slow Downer from Roni Music is one of the best-known slow-down apps for musicians, and a big part of why LoopTube exists — it's a great tool. It's a paid app you install on your computer or phone. If you'd rather not install anything, want to work straight from YouTube, or are looking for a free option, LoopTubedoes the core job in your browser: slow a recording down without changing the pitch, loop the bar you're stuck on, and — for audio files — shift it into a different key.

A Web-Based Amazing Slow Downer Alternative

Because LoopTube runs in the browser, there's nothing to download and it works the same on Windows, Mac, Chromebook, iPhone, iPad and Android. Audio is processed on your own device, and YouTube is built in — paste a link instead of hunting down an MP3.

When Amazing Slow Downer Is the Better Choice

  • You want an equalizer to bring out the bass line or a single instrument.
  • You play straight from your music library on your phone.
  • You already own it and it fits the way you practise.

When LoopTube Is the Better Choice

  • The version you want to learn is on YouTube — paste the link, no file needed.
  • You don't want to install or pay for another app.
  • You switch between laptop and phone — it's the same tool in any browser.
  • You teach: send a student a link that opens on the exact loop, or embed the looper on your own site.

How to Slow Down a Song in LoopTube

  1. Add your music — paste a YouTube link on the homepage, or open LoopTube and drop in an MP3, WAV or M4A file.
  2. Set a loop — drag the A and B markers around the passage you're learning.
  3. Slow it down — drag Tempo down; the pitch stays put. On an audio file you can shift the key separately too.

Frequently Asked Questions

Is there a free alternative to Amazing Slow Downer?

Yes. LoopTube is free and runs in your browser: upload an MP3 or other audio file, or paste a YouTube link, then slow it down without changing the pitch and loop any section — and on your own audio files, shift the key too. LoopTube Pro adds exporting, keeping files on your device between sessions, and cloud-synced loops.

Is there an online version of Amazing Slow Downer?

Amazing Slow Downer is sold as installed apps — for Windows, Mac, iPhone/iPad and Android. If you want the same core tools without installing anything, LoopTube runs entirely in the browser, on desktop or phone, and can be added to your home screen like an app.

Can LoopTube slow down a song without changing the pitch?

Yes. Drag the Tempo slider anywhere from 25% to 200% and the pitch stays where it is. On your own audio files, pitch is a separate control too — shift up or down by up to 12 semitones without the tempo moving. (YouTube's player only allows speed changes, not key changes.)

Can I slow down a YouTube video the same way?

Yes — that's what LoopTube started as. Paste a YouTube link, set A and B loop points, and slow it down. You don't need a copy of the audio file first.

Is my audio uploaded anywhere?

No. Your file is decoded and processed in your browser and never sent to a server. If you save loop points, only the start and end times sync — never the audio.

Is LoopTube affiliated with Roni Music?

No. Amazing Slow Downer is made by Roni Music. LoopTube is an independent tool and is not affiliated with or endorsed by Roni Music.
