Raspberry Pi 5 MEMS Mic Array Beamforming Kit for Sound Localisation
Build a 4-Element MEMS Mic Array Beamformer on Raspberry Pi 5 - Real-Time Sound Source Localisation
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform a Raspberry Pi 5 into a professional-grade acoustic sensor that pinpoints sound sources in real time. This advanced lab kit packs everything you need to assemble a 4-element MEMS microphone array and run beamforming algorithms, turning DSP theory into a working directional hearing system. Built for research labs, final-year projects, and serious tinkerers who want a complete, no-hassle platform for sound localisation experiments.
What You'll Build
You'll assemble a compact, NVMe-powered microphone array that captures 4-channel audio and computes direction-of-arrival angles on the fly. The system streams spatial data, tracks voices or environmental sounds with sub-degree accuracy, and can output real-time polar plots to a display or over Wi-Fi. The finished rig is a self-contained instrument ready for algorithm testing, robotics, or IoT monitoring projects.
What You'll Learn
- Implement delay-and-sum and MVDR beamforming on live 4-channel microphone streams
- Process audio data in real time with Python, numpy, and PyAudio on Raspberry Pi 5
- Calibrate MEMS microphone arrays for accurate time-difference-of-arrival measurements
- Visualize sound field direction and intensity using polar and heatmap plots

Who This Kit Is For
Designed for final-year B.Tech (ECE/EEE) students building DSP or acoustics capstone projects, M.Tech researchers exploring array signal processing, and participants in Smart India Hackathon or institutional labs at IITs, NITs, and VIT. This kit also fits ATL Tinkering Labs looking to demonstrate advanced beamforming concepts to senior students.
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 free within 7 days.
What if I get stuck during the build?
Our AI companion walks you through every step-from attaching the ReSpeaker HAT to running the first beamforming script-and you can reach us on WhatsApp for quick troubleshooting.
Do I need prior DSP experience to complete this project?
The kit includes pre-written Python scripts for basic delay-and-sum beamforming. Even without a deep DSP background you'll be collecting direction data within hours, while the AI companion explains each algorithm step by step.
Can this array locate a human voice in a noisy room?
Yes, the included beamforming algorithms are tuned to isolate narrowband signals like speech, and can track a talking person in real time, outputting their azimuth angle on a live plot.
Are all the required software libraries included?
The AI companion guides you through installing Python, PyAudio, numpy, scipy, and matplotlib onto the NVMe SSD, ensuring fast, glitch-free execution of the full beamforming pipeline.
