About this app

Riffloop is a practice tool for musicians. Split any song into stems, remove the vocals, isolate the drums or the bass, then loop the part you are learning and slow it down without changing the pitch. Everything runs on your phone. Nothing is uploaded.

STEM SPLITTER
Pick a song from your phone and choose what you need: vocals, drums, bass, other, or all four at once. On phones with enough memory, a six-stem mode adds guitar and piano. Mute or solo any stem, set each one's volume, and export the stems as WAV files.

VOCAL REMOVER
Remove the vocals from any track and sing over the band. Keep a quiet guide vocal if you want a reference while you learn the melody. Works as a karaoke maker and as a backing-track maker.

BACKING TRACK
Take one instrument out and play its part yourself. Drop the bass and be the bassist, drop the drums and be the drummer.

PRACTICE LOOPER
Choose a section with two handles, loop it, and slow it down from half speed up to normal. Transpose up or down by semitones. Save loops with a name and come back to them later.

LOOP ANY YOUTUBE VIDEO
Paste a link and loop any part of the video in the official YouTube player, with playback speed control. The video stays on YouTube; Riffloop only controls the player.

PRIVATE BY DESIGN
Separation runs on the device with on-device AI models. Your songs, stems and loops stay on your phone. No account, no upload, no tracking.

Riffloop is made by musicians. It also exists as Riffloop Studio on the web and as a Chrome extension for YouTube. Questions: [e-mail]
