>The tone is generated using two sawtooth oscillators

I interpreted "acoustically-accurate" to mean physically modeled in some way. Filtered sawtooth makes a simple brass-like timbre, but 80% still sounds synthetic.

Really neat anyways, thanks for sharing.

Doesn't really sound like a trombone?

There are limits to the web audio API :) but I did conform to the known waveforms of the trombone when setting the synthesizer values. The frequencies and proportions of the slides and partials are very precise!
