The sensory bridge is your way to an office rave
[Lixie Labs] is no stranger to creating many projects with LEDs or other displays. They have now created a low latency music visualizer, called Sensory Bridge, which creates beautiful light shows from music.
The sensory bridge has the ability to update up to 128 RGB LEDs at 60 fps. The unit has a built-in MEMS microphone that picks up ambient music to produce the light show. The chip is an ESP32-S2 that performs Fast Fourier Transform trickery to enable real-time RGB array updates. The LED terminal supports common WS2812B LED pinouts (5V, GND, DATA). The Sensory Bridge also has an "accessory port" that can be used for hardware expansions, such as a base for their LED "mini mast", a long strip of RGB matrix PCB.
The device is powered by a 5V 2A USB-C connector. Various buttons on the device allow you to adjust the brightness, microphone sensitivity and LED strip responsiveness. One of the coolest features is its "noise calibration" which can record ambient sound and subtract frequency components from the background noise to give a cleaner music signal. The Sensory Bridge is still new and it looks like some of the features are yet to come, like WiFi communication, accessory port upgrades, and 3.5mm audio input to bypass the built-in microphone.
>The stated goals of the Sensory Bridge are to provide an open, powerful, and flexible platform. This can be seen with their commitment to releasing the project as open source hardware, providing firmware, PCB design files, and even case STLs under a free/libre license. Audio Spectrum Analyzers are our favorite and we've seen many different iterations ranging from those using Raspberry Pis to others using ESP32s.
