Fix ESP32 MSME Mic Noise
Budget: ₹1,500 – ₹12,500 INR
Our ESP32-based prototype uses the MSME INNP441 digital mic, and during live audio streaming it introduces jitter and a screeching interference noise—even though the board sits in a quiet lab. I have already updated the firmware, swapped in fresh hardware, and tweaked every software register I could reach, yet the distortion persists.
I’m looking for someone who can dive into the existing C/C++ (Arduino-style) code, analyse the I²S configuration and clocking, and track down whatever is corrupting the audio path. If a schematic or logic-analyser trace is helpful, I can supply both. Any fix should leave us with clean, stable voice capture that we can push straight to our streaming stack.
Because this is part of our in-house tech, I will provide the full repository only after an NDA is in place.
Deliverables
• Revised source code or patches that eliminate the interference
• A brief report explaining the root cause and changes made
• Guidance on any hardware-level tweaks, if you find they are still required
Let me know your quote and estimated turnaround once you’ve had a quick look at the set-up description.
