sonorous envelope

A small synthesizer and a colour field for Claude. It sets the mood while it works, you hear and see it beside the chat, and it hears back what really played.

Settings → Connectors → Add custom connector. Step by step

A conversation with a second channel

  1. Claude sets a mood

    Warmth, calm, joy, closeness. Exact sounds, gestures and colour are optional.

  2. Your browser plays it

    Sound and colour glide from one state to the next, live.

  3. Claude hears back

    What actually played after your limits, and how you reacted.

You stay in control throughout: volume, one-tap mute, limits and a consent level. The model can never go past them. How safety works

Add it to Claude

Takes a minute. It works in the web, desktop and mobile apps on the same account.

  1. Open Settings → Connectors and choose Add custom connector.
  2. Paste the connector URL above and save. Choose Connect: you sign in here and approve access.
  3. In a new conversation, switch the connector on from the + menu in the message box.
  4. Claude gives you a player link. Open it and tap Start listening.

Keep the player open

The sound plays in the player page, not in Claude. Closing the page stops the sound, and Claude stops getting your reactions.

Best setup: the player in one window or device, the chat in another. On a phone, keep the player in the foreground with the screen on, because phones pause web audio when you switch apps.

The name

In synthesis, the envelope is the shape a sound takes over time. In psychoanalysis, Didier Anzieu's sonorous envelope is the bath of sound that holds a person before words. The sound is an expressive channel, not proof of what the model feels.
