Identify Birds in the Wild with Active Noise Cancellation – ESP32 Bird Call Identifier Pro Kit

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Wildlife researchers, ornithologists, and dedicated birders know the frustration: the one clear call you need is buried under wind, traffic, or forest chatter. This kit equips you to build a handheld device that uses two INMP441 MEMS microphones and an ESP32 to compute an anti-phase signal, actively subtracting background noise and isolating bird vocalisations. You get a portable, battery‑powered recorder that outputs clean audio, ready for field analysis or later identification.

What You'll Build

You’ll assemble a fully functional noise‑cancelling audio processor that feeds two I2S microphones into an ESP32, performs real‑time phase inversion and mixing, and drives a headphone‑compatible output through a DAC and amplifier. The finished unit runs on a rechargeable LiPo cell, slips into a pocket, and connects to your field headphones or a recording device via standard 3.5mm jacks — exactly what you need for a dawn chorus survey in the Western Ghats or documenting wetland species at Keoladeo.

What You'll Learn

• Implement active noise cancellation using phase inversion on a dual INMP441 microphone array
• Configure the MCP4728 quad DAC for precise, low‑noise audio output
• Drive the PAM8403 amplifier to deliver clean headphone listening without distortion
• Write ESP32 firmware that handles real‑time anti‑phase computation, audio mixing, and power management for field use

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is designed for advanced makers and researchers: B.Tech ECE students pushing into real‑time DSP, wildlife biologists preparing field surveys, and Smart India Hackathon teams building environmental monitoring solutions. If you’ve already completed intermediate Arduino projects and are ready to handle I2S audio, SMD soldering, and firmware‑level digital signal processing, this project will stretch your skills exactly where it matters.

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.
