ESP32-S3 Neural Style Audio FX Kit with ESP32
ESP32-S3 Neural Audio FX Kit: Build a Real-Time Convolution Reverb Processor on ESP32
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This kit transforms audio in real time by applying room impulse response convolution reverb directly on the ESP32-S3's vector processing unit. You'll capture 16kHz audio from the INMP441 I2S microphone, run optimized convolution filter weights, and hear spatially-rich reverb through the amplified speaker. Perfect for audio engineers, DSP enthusiasts, and engineering students wanting to implement professional audio effects on a microcontroller.
What You'll Build
You'll assemble a portable neural audio effects unit that captures sound through an I2S MEMS microphone, processes it using convolutional reverb algorithms accelerated on the ESP32-S3's SIMD vector unit, and outputs studio-quality audio through a 3W speaker. The build includes soldering the custom analog circuit, integrating the MCP4725 DAC and PAM8403 amplifier, and calibrating real-time filter coefficients for different room impulse responses. This is a full signal chain from acoustic capture to processed playback.
What You'll Learn
- Real-time I2S audio input/output configuration on ESP32-S3
- Implementation of time-domain convolution filtering using vector instructions
- Designing low-noise analog audio circuits with DAC and amplifier
- Optimizing DSP algorithms for embedded microcontrollers
