How slow-down apps work, and what to listen for
Every app here uses time-stretching: it changes the speed without changing the pitch. The amount of audible smearing depends on the algorithm, recording and playback speed. Test with the fastest passage you actually need to learn, on headphones, before you pay for anything.
1. Transcribe!: best for serious transcription on a computer
Transcribe! has been the standard desktop tool for working out parts for years. It slows audio precisely, loops named sections, shows a spectrum view that helps you identify notes, guesses chords and plays video. It is a one-off licence on Windows, Mac and Linux. There is no phone version and it does not separate stems.
Official reference: Transcribe! features and platforms.
2. Anytune: best on iPhone and iPad
Anytune offers very slow playback, shifts pitch over a wide range, and has flexible marks and loops, all working offline. It is a one-off purchase on Apple devices. There is no Windows or web version; see Anytune alternatives if that rules it out, or StemConsole vs Anytune for the head to head.
Official reference: Anytune platforms and features.
3. Amazing Slow Downer: simplest cross-platform option
Amazing Slow Downer does slow-down, key change and loops on Windows, Mac, iPhone and Android without much else to learn. It is a one-off purchase per platform and works on your own audio files.
Official reference: Amazing Slow Downer platforms.
4. Moises: stems and chords in one app
Moises combines AI stem separation with chord detection, speed and pitch controls and a metronome, on the web and in mobile apps. It combines separation and practice tools, with additional features on paid plans.
Official reference: Moises stem separation.
5. Capo: best for learning chords by ear
Capo is built around detecting the chords in a song while you slow it down and loop it. It is Apple only. If chord detection is what you need most, Capo or Moises will serve you better than a pure slow-downer.
Official reference: Capo features and supported devices.
6. StemConsole: best for hearing one instrument while slowed down
StemConsole has a free speed and key player in the browser. Open a song and it plays the whole track from 50% to 150% speed with the pitch kept, moves the key up to 12 semitones either way, and loops a passage with an A/B loop on the waveform. It needs no account, and nothing uploads: the song plays on your device. With a free account, Download MP3 saves the whole song at your speed and key as an MP3, made on your device.
To hear one instrument while it is slowed down, StemConsole separates the song into stems, so you can solo the part you are learning, or mute your own instrument and play along. Pro changes speed and key on the separate stems and adds named loops, tap tempo and count-in. It works on any device with a browser, and every split song stays in your library with a share link. It does not go slower than 50%, does not detect chords, and needs an internet connection.
StemConsole plans: free covers vocal removal and a 4-stem split (vocals, drums, bass, other), 5 splits a month, the live mixer, a basic A/B loop, a saved library, share links, key and BPM analysis, song-following click, manual BPM and tap tempo, and a speed and key player that plays a whole song at any speed from 50% to 150% or moves its key up or down 12 semitones in the browser, and saves the result as an MP3 with a free account. Pro is US$6.99 a month or US$49 a year and adds 6 stems with guitar and piano, WAV, 100 splits a month, and the practice room tools on the separated stems: speed from 50% to 150% without changing pitch, key change up or down 12 semitones, multiple named loops and count-in. A US$1.99 credit buys one 6-stem split with MP3 downloads and basic A/B looping. WAV, speed and key change on stems, and multiple named loops require Pro.
7. AudioStretch: wide speed range on a phone
AudioStretch is a lightweight iPhone and Android app with a very wide speed range and a free Lite version on iOS. A good budget choice if all you need is slow playback on your phone.
Official reference: AudioStretch versions.
8. YouTube playback speed: free and instant
The playback speed setting on YouTube slows a video without changing its pitch, for free. It is fine for a quick listen, but it has no proper A/B loop without a browser extension, and the audio gets washy at low speeds.

Frequently asked questions
What is the best app to slow down music without changing pitch?
It depends on your device and goal. Transcribe! for desktop transcription, Anytune on iPhone and iPad, Amazing Slow Downer for a simple cross-platform app, Moises or Capo if you want chords, and StemConsole if you want to isolate one instrument while it is slowed down in a browser.
Is there a free app to slow down music?
Yes. YouTube’s playback speed setting is free for YouTube videos, Audacity’s Change Tempo effect is free on desktop, and AudioStretch has a free Lite version on iOS. StemConsole’s speed and key player is free in any browser: it plays a whole song at any speed from 50% to 150% with the pitch kept, with no account and nothing uploaded. Slowing down separate stems is Pro.
How slow can I go before it sounds bad?
There is no single speed threshold: audible smearing depends on the algorithm and recording. For very fast passages, loop a single beat at a moderate speed rather than slowing the whole song right down.
Can I slow down a Spotify or Apple Music song?
Most tools here work with local audio files. Streaming support varies by app and platform, so check the current app documentation before choosing a tool for Spotify or Apple Music.

Dan Murtagh is a Melbourne mixing and mastering engineer with 20 years making records and a decade teaching audio. He built StemConsole as a practice tool for his students. More about Dan.
