sound-to-light-osc

Real-time detection of beats with Python from an audio input device (typically "Stereo Mix"). Outputs OSC signals, to be used for sound-to-light control.

It keeps track of the music "intensity" (calm, normal, intense) to switch lighting programs.

I use QLC+ for DMX control.

Required modules

• PyAudio
• PyQt5
• PyQwt
• matplotlib
• scipy
• python-osc

Usage

python beatDetector.py

Automatically listens to default audio input device.

OSC Signals

OSC signals are sent to localhost:7701, can be changed in beatDetector.py.

• /beat is sent for every beat detected.
• /bar is sent every to change the lighting scene.
• /prog1 - /prog8 is sent to change lighting programs (available have to be configured in beatDetector.py)
