lightfall-vibe

The Lightfall plugin you didn't know you didn't need.

Vibe mode for Lightfall: a demo plugin that makes the UI react to whatever music is playing.

• Spinner — the RunEngine spinner spins with the music's energy
• Theme — accent colors hue-walk on every beat; borders get a subtle wash
• Dock pulse — the layout blips on downbeats (every Nth beat, off by default)
• Spectrum panel — a live 24-band analyzer showing the audio driving it all

Beat detection is kick-focused (40–160 Hz spectral flux) and anchored to the strength of recent kicks, so it goes quiet when the kicks pause instead of triggering on whatever's left.

Audio comes from system loopback by default (WASAPI on Windows, PulseAudio/ PipeWire monitor sources on Linux) via soundcard, so it reacts to whatever you're playing — or pick a microphone in settings.

Install

Install into the same environment that runs Lightfall:

pip install -e .

Then in Lightfall: Preferences → Vibe → pick a device, hit Enable, play music.

Development

python -m venv .venv
.venv/Scripts/python -m pip install -e ../lightfall -e .[dev]
.venv/Scripts/python -m pytest

This is a toy. It pokes one private attribute of the host's spinner widget and is proud of it.
