Our high quality time stretching algorithm ensures that the pitch and quality of the sound remain as natural as possible. You can slow down as much as much as 25% of the original tempo, or speed up to double speed and everywhere in between. Our amazing slow down tool lets you slow down or speed up any song in your music collection without affecting the pitch. With Riffstation, you can set the pace! Slow down any song without affecting the pitch and sync a metronome to help with your timing. You can use our chord edit feature to manually modify the chords if required. Our chord recognition algorithm detects major and minor chords with approximately 80% accuracy for popular music. It’s guitar hero for real guitar players! Load any song and our technology will automatically calculate the chord accompaniment in a few seconds. Riffstation even shows you how and when to play each guitar chord synced with the original music. Riffstation uses automatic chord recognition technology to ‘listen’ to the music and figure out the chords for you.
