Play detections in chronological order at 100 ms intervals, or select a 30-second calendar timeline that preserves relative gaps including breaks between observing runs, with each event’s components starting together, using mass-scaled equal-mass, nonspinning model chirps. This replaces the played distribution. It builds event by event as sounds start; after all events it matches the catalog. Stopping early keeps only events already started. Uses the current Musical/Scientific mode; these are model sounds, not detector recordings. Press again to stop or cancel preparation. Highlighted background lines show the nearest piano notes as each event starts; exact catalog masses determine the audio. Each highlight clears when its component sound ends; overlapping sounds on the same note keep that line lit.

■ LVK components ▧ Lime stripes: played components · □ White: currently sounding│ Lines: keyboard notes

The purple bars show LVK components; lime-striped bars show played components. White bars mark bins containing sounds currently playing; they return to lime stripes when those sounds end. Muted solid lines behind the bars mark piano notes’ component masses within the 0–150 M☉ range (all 88 notes remain in the table). Every note through A2 is labelled, then every second semitone through A3, followed by A notes above A3. Colours repeat every octave (all Cs share a colour); the most recently played note has a thicker line. Hover over a line for its note, or open the note-mass table below. Exact counts are available in the table below. The mass axis is linear, with 2 M☉ bins. Both series fill each bin’s width. Bar heights are component counts per bin, on a shared vertical scale. Each successful note playback contributes two equal-mass bodies; repetitions count. Played masses assume zero redshift; catalog masses are source-frame medians. This is a comparison of sounds with detections, not a population inference.
