How it looks1 / 4

A Jitsi Meet call between Ada Lovelace, Alan Turing, Hypatia, and Mary Somerville, with a separate audio visualization attached to each participant — **Jitsi Meet**One graph per tile. The steady line under Mary Somerville’s spectrogram is her fan.

A Google Meet conversation about whether the Analytical Engine could compose music between Charles Babbage, Mary Somerville, Michael Faraday, and Ada Lovelace, with four different audio views — **Google Meet**Pick a view per tile: level history, waveform, spectrogram. Ada Lovelace is speaking, Michael Faraday just finished.

A Microsoft Teams call about calendar reform between Julius Caesar, Cleopatra, Cicero, and Sosigenes, with a separate audio visualization on every participant — **Microsoft Teams**Spectrograms keep the last 15 seconds: Cicero spoke a moment ago, Sosigenes is speaking now.

A Nextcloud Talk call between Albert Einstein, Ernest Rutherford, Henri Poincaré, and Marie Curie, with two spectrograms, a waveform, and a level history shown on separate participant cards — **Nextcloud Talk**Henri Poincaré’s waveform moves live, Marie Curie’s level history holds her last words.

Join the call in your browser and click the bookmark. Every participant gets their own graph, right on their video:

Nextcloud Talk

Microsoft Teams

Best effort: WhatsApp and other browser calls get a floating panel with whatever audio the page makes available.

Each graph has a button that switches between four views (waveform, 15-second level history, spectrum, 15-second spectrogram) and a − that collapses it.
