Psychoacoustic Masking Synthesiser Variant 15 Kit with ESP32 + LED
Psychoacoustic Masking Synthesiser Variant 15 Kit – ESP32 Audio & Music Project
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 enables you to build a synthesizer that applies psychoacoustic masking principles — generating audio signals just below the threshold of human hearing to create subtle layers and illusions. Perfect for sound designers, music producers, and engineering students exploring real-time audio perception, the project uses an ESP32 to analyse ambient sound via a MEMS microphone and produce complementary masked tones through a high-quality DAC and amplifier.
What You'll Build
You will assemble a standalone stereo synthesizer with dual rotary encoder controls, an OLED status display, and a robust enclosure. The system continuously captures ambient audio, computes FFT-based spectral analysis, and synthesises frequency bands that exploit simultaneous and temporal masking, delivering a unique sonic experience. Connect external audio or use the built-in mic — the result is a hands-on tool for sound design and research.
What You'll Learn
- Implementing real-time psychoacoustic models (simultaneous and temporal masking) on the ESP32
- Interfacing and programming the MCP4728 I2S DAC and MAX9814 MEMS microphone
- Performing FFT analysis and synthesizing masked audio bands in C++
- Soldering, assembling, and packaging a multi-PCB audio system with a custom enclosure

Who This Kit Is For
This kit is tailored for B.Tech ECE/EEE final-year students undertaking advanced audio DSP projects, researchers at IIT/NIT/VIT/BITS working on psychoacoustics, and professional sound designers or musicians who want to build a custom masking synthesizer. It is also an excellent platform for Smart India Hackathon teams exploring real-time audio processing and embedded systems.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it
ESP32 implements psychoacoustic masking model to synthesise audio in frequency bands just below hearing threshold.
