'YouTube Musical Spectrum ' is

an extension that creates a spectrogram from the voice played on YouTube and automatically converts it into a musical score using the notes of flowing light. It is distributed free of charge for Google Chrome and Mozilla Firefox, and is useful for making 'playing by ear ' that is difficult without perfect pitch.

YouTube Musical Spectrum is a useful add-on for anyone who wants to play or arrange by themselves, as the pitch is visualized and you can copy your ears without perfect pitch.

And when I tried the software voice changer ' Gachikoe! Core ', I used YouTube Musical Spectrum in the movie that sang 'Spring Stream' in the following movie. , You can see that only the left and right positions shift according to the pitch.
