don't make a sound
20 HP
Something out there hunts by sound. Under the line your mix passes untouched. Over it, a clicking starts in the dark, turns towards the loud sound and comes nearer with every one. Stay loud and it strikes: the moment torn apart, then dead silence.
Turn a knob: drag it or tap either side of it, roll the wheel over it or use the arrow keys; a double click puts it back. FIRE is a button: press it. The patches step on by themselves until you touch anything.

Everything HUSH does here is its engine as designed, running in your browser. The loop is a stand-in rack.
Under the line nothing happens at all: what comes out of HUSH is what went in, to the bit. The path down the middle shows your level, and flashes when a sound gets to its far end.
