Everything audiotoggle does

One tool, one job: hearing the difference between two versions — and showing it to others.

Zero-latency A/B

Both versions play in perfect sync. Holding the button flips which one you hear — instantly, mid-note.

Web Audio switching — no gap, no click, no fade
Pin a version, seek anywhere, both tracks stay locked in time
Works with the spacebar too
