USB Audio That Behaves Like A Product
Building a microphone is not just reading samples. The device has to enumerate correctly, expose the right audio interface, stream reliably, and feel plug-and-play on the computers customers already use.

Why It Matters
Audio hardware has to satisfy the customer and the operating system.
For customers, a USB microphone should simply appear and work. Behind that simplicity is a chain of product decisions: microphone selection, I2S timing, sample buffering, USB descriptors, host compatibility, status feedback, and physical assembly. This kind of prototype proves the full path before a team commits to a product direction.
What The Platform Shows
Embedded audio work from signal input to customer-ready USB output.
Embedded Capture From Digital Microphones
Digital MEMS microphones commonly speak I2S, which means firmware needs to coordinate clocks, channels, sample timing, buffering, and conversion before audio can reach a host application.
Low-Level Firmware And Driver Awareness
USB audio products sit between hardware constraints and operating-system expectations. Good firmware has to respect both sides: microcontroller timing, memory, interrupts, descriptors, and host compatibility.
Prototype Thinking Across Electronics And Enclosure
A convincing audio hardware prototype needs more than a board on a desk. Mechanical placement, microphone orientation, cable access, status feedback, and assembly all shape the final product experience.

System Design
The hard part is making the path between parts reliable.
A microphone module, a microcontroller, and a USB connector do not automatically become a product. The engineering value is in the timing, buffering, interface definitions, diagnostics, and product behavior that make the device predictable under real use.
Client Applications
