What problem does it solve?
Real-time audio analysis and LED pattern generation on ESP32-S3 for audio-reactive visuals.
Core Features & Use Cases
- I2S audio input configuration: PDM or analog input at 44.1 kHz.
- FFT analysis with CMSIS-DSP: 256-point FFT, magnitude spectrum, windowing.
- Feature extraction & beat detection: Bass/mid/treble energy, dominant frequency, beat events.
- LED pattern generation: Drive LEDs in sync with audio.
Quick Start
Configure the ESP32-S3 I2S input and run the FFT-based analysis to drive LED patterns in real-time. For example, feed 44.1 kHz audio and map bass to low-resolution LEDs.
