Project description:
"I am refining the next-generation version of our digital stethoscope and the priority is adding robust active, adaptive noise-cancellation that can cope with the environmental noise typical on busy hospital wards—human conversation, fan, ventilators humming, trolleys rolling, HVAC systems, the works. We must achieve a high level of reduction so that heart and lung sounds remain crisp and clinically useful even when the surroundings are anything but quiet.

What I need from you is a good firmware engineer with exposure to Analog / TI / Qualcom chipsets, good understanding of the audio filters, adaptive control strategy, deep DSP know-how translated into a practical solution: a signal-processing architecture, filter design, and adaptive control strategy that can run in real time on our existing MCU/codec platform (ARM Cortex-M with floating-point support). I

Hardware solution that can be interfaced / incorporated within our ready hardware, MIC selections (for auscultation as well as ambient), housing of the MICs, software / firmware." (client-provided description)
