Hi, me again.
Felt like the buzzer could do with a glow-up, as it has no visual feedback when beeping and booping.
So I gave it a display that oscillates with the frequency and amplitude of the input:

Always nice to have more visuals to look at in my opinion.
They are currently a bit buggy when used as displays in other chips, I'll work on that tomorrow.
