About this extension
OpenPitch is a browser extension that changes the pitch of audio playing in your browser in real time. You can shift audio by semitones or make smaller adjustments in cents, with optional smart processing and configurable block sizes for balancing quality and latency.
The extension runs entirely in your browser and does not upload or transmit audio to external servers.
OpenPitch is useful for practicing music in a different key, matching your vocal range, transcribing songs, or simply experimenting with audio.
