The built-in metronome on the website practice assistant seems to be crazy loud.
To make the metronome sound tolerable, I have to turn my overall computer volume & speakers down so low that nothing else is audible.
Not sure why it’s so much louder than everything else my computer is outputting, but I think a separate volume control on the metronome widget would solve the problem for me.
