Change one thing.
Hear what follows.
Base frequency shifts the pitch or noise-band center. Pulse interval changes the space between gestures. Character changes the source itself. The pattern belongs to the selected sketch.
Round
Rounded sine / 700 ms pulses
Stopped / no output
Live output waveform Measured after output gain / not a sound-pressure meter
Sound starts only when you choose Start. Begin with a low device volume.
Four rounded pulses: two return to the same pitch, the third lifts gently, and the fourth comes home.
A quiet interface transition study. Explore a recognizable change without a sharp alarm-like edge.

The record describes synthesis settings. It is not a measured room level, finished audio asset or tested product recommendation.
Identify the state change and its visual alternative before deciding whether sound helps.
