Slow Down Buddy can record whatever a website is playing and save it straight to your library, ready to slow down, loop and transpose. On a computer, open the page with the music in another tab of Chrome, Edge or Brave (or another Chrome-based browser), press the screen button in the toolbar, choose that tab, switch on “Share tab audio”, and play the part you want. Press “Stop and add to library” when you’re done. The microphone button records anything you can play out loud, on any device.
