## Description

PitchShifter changes the musical pitch of video and audio playing in your browser in real time, without changing playback speed. It can also change playback speed while keeping the original pitch.

Great for musicians transposing songs, singers and karaoke, language learners slowing down speech, or anyone who wants to hear audio in a different key.
