About Audio speed changer
Speed up a lecture, podcast or audiobook, or slow down a hard passage to learn a song. Speeds from 0.5 times to 2 times are supported, and the voice option keeps pitch natural, so people do not sound like chipmunks. Without that correction, faster playback also raises the pitch.
