re: Yep. I asked if it is trained for frequency or the tone? or both?

If by tone you mean notes, notes are named frequencies.

The data you get back from the WebAudio API is the frequencies picked up by the microphone copied into a Uint8Array using the getFrequencyByteData method on the AnalyserNode.

By tone, I meant tone: which makes a C note from violin and piano distinct.

However, I got what you meant. Nice and creative work!

Notes are just particular frequencies that are given a name. In any case, the tone you're using is a bit off.

Traditionally, that's referred to as timbre. It's the volume of specific frequencies in a note's harmonic series that account for differences in timbre in pitched instruments. Here's a great video explaining how that works.
