Riffloop

Riffloop is an all-in-one music practice studio that runs right under the YouTube video you are already watching. AI stem separation splits any song into six parts: vocals, drums, bass, guitar, piano and more. Solo the guitar to learn a riff note for note, or mute the vocal and sing it yourself. Drag a region over the bar that trips you up and loop it, snapped to the beat, until it sticks. Pull the tempo down to 25% to catch every note with the pitch held steady, then walk it back up to full speed. Shift the whole track up or down by as much as 12 semitones to fit your voice or instrument. It works on your own files too. Upload an MP3, WAV or FLAC to the web Studio and get the same stems, loops, speed and key controls. Most tools give you half of this. A stem splitter hands you files and walks away. A looper forgets the stems. Riffloop keeps all of it in one place, on the song you are already learning. Free to start, no signup needed to try it.
