Capo – Pitch & Speed Changer geliştiren: Elyra Labs, John Norback

Capo lets you change the pitch, speed, and volume of any audio or video on any website — YouTube, Spotify Web, SoundCloud, podcasts, lectures, and more.

Whether you're learning a song, slowing down speech to study a language, or just making a quiet video louder, Capo gives you studio-style control right in your browser.
