Transpose by Chordify Autor: Chordify

Transposes the audio when using the transpose feature on Chordify. Also works on YouTube.

Chordify gives you the chords for any song, and will teach you how to play along with guitar, piano, ukulele or mandolin. Chordify Premium includes a feature that transposes the chords to the key that you prefer. This extension improves the transpose feature by also transposing the audio that you hear, using a high quality pitch shifting algorithm*. Great for jamming and singing along in your preferred key!

If you don't have Chordify Premium yet, but you want to check out how the audio transposing works and sounds, you can try this extension with the demo songs listed here: https://chordify.net/setlists/premium, or you give it a go on YouTube, where this extension also provides transposing support.
