AudioBridge is a hybrid digital Eurorack module that converts incoming audio into both control voltages and real-time visuals. It uses a high-speed FFT running on a Teensy 4.0 to analyse audio and split it into four frequency bands, which are output as smooth, responsive CV signals for modulation. At the same time, the spectral data is sent to a second processor that generates retro-inspired graphics.
The module features four CV outputs (low to high bands), an audio input and thru, an onboard 128×128 TFT screen, and HDMI output for external displays. Visuals include spectrum bars, geometric patterns, and rhythmic animations that directly follow the sound.
Controls and menus allow adjustment of input gain, attack/decay, sensitivity, visual effects, layouts, and themes. AudioBridge is designed to tightly link sound, modulation, and motion graphics in a single Eurorack module, making it useful both as a performance tool and a visual extension of a modular system.
