Hear the midpoint before you see the answer.

This prototype maps each binary-search probe to a tone across a 1000-value array. Lower values sound lower, higher values sound higher, and the found target resolves with a brighter hit so the algorithm becomes a short audible phrase instead of just a visual trace.

Quick note

The main controls stay pinned under the site navigation while you scroll through the probe bars and search trace. After the run finishes, hover a step to replay that probe.

Each midpoint probe produces one note.

Successful search resolves with an overtone.

Missing target ends with a muted low tone.
