What's New in Slow Down Music | Transcribe+

1.8.74

June 24, 2026

Reverted recent changes to the way the music picker worked. Some users preferred the old method and this may also resolve a few cases of iCloud being in limbo and preventing users from accessing music that is downloaded to the device.

Awesome

Everything a learning jazz musician needs

Thoughtful Features

The addition to manually input BPM, manually fade volumes of each isolated track, and tap the tempo are very thoughtful features. You guys listen to your users! Props!!

So clean. So useful

This app lets you download music and slow down and/or change keys. So useful and a great UI

Can’t trial ANYTHING without signing up to a subscription.

After install you’re immediately shown a ‘purchase subscription’ page that you can’t get past without choosing a yearly plan. If you’re going to do this, just put a price on it up front. Was going to compare it to Transcribe! Which is $39 for a lifetime license. Thought if it has better vocal removal than that I might use it.

Amazing tool that predates all the new AI

This is a great tool on the iPhone and iPad. It’s been a star for years well before all the new AI stuff showed up and it does all of that and more very very well.

FAQ

What does this app do?

This app is designed to help musicians transcribe and practice music by allowing them to adjust the tempo and pitch of songs. It uses AI to isolate vocals, drums, bass, and other instruments, making it easier to focus on specific parts.

What are the key features for practicing music?

Key features include adjustable speed from 0.25x to 2x without pitch change, pitch modification up to ±12 semitones with fine-tuning, an interactive waveform for note-by-note listening, and customizable looping with 'Smart Loops' that can automatically adjust speed or pitch.

How does the AI instrument isolation work?

The app's on-device AI can separate any track into 2 or 4 stems: vocals, bass, drums, and instrumentals. This allows users to isolate specific instruments to hear them clearly for transcription or to create play-along tracks.

Is this app compatible with Apple Music?

Yes, the app integrates with Apple Music, allowing you to adjust tempo and add flags and loops to songs from your library. However, due to DRM limitations on streaming music, some features may not be available on Apple Music tracks.

How is my data saved and synced?

All your flags, loops, and settings for each track are automatically saved to iCloud. This ensures your progress and configurations sync seamlessly across all your devices, providing a consistent experience.
