I built a music website with AI, as I noticed no one has combined all these features in one place.

I spent some time developing a vocal range testing site, and further integrated pitch accuracy tests (sing a specified pitch), ear training tests (listen to a tone and identify its note), plus a fun tone color evaluation feature.
The whole project started casually back at a KTV, when a friend pointed out I tended to sing out of tune. That inspired me to build this tool. Hopefully it can help other singing enthusiasts improve their vocal skills.
