About this Gig

Looking for a custom embedded audio solution? I design high-performance, low-noise audio hardware integrating microphones, speakers, and DSPs from concept to production-ready Gerber files.


What I Offer:

Microphone Integration: PDM/I2S digital MEMS arrays or low-noise analog circuits.

Speaker & Amplifier Tuning: Class-D audio amplifier design, impedance matching, and protection blocks.

DSP & Codec Architecture: Integration of audio processors (e.g., XMOS, STM32, Texas Instruments, ADAU DSPs).

PCB Design: Multi-layer layouts focused on signal integrity, isolation of analog/digital planes, and low distortion.

Interface Protocols: Expert configuration of I2S, TDM, PDM, SPI, and I2C lines.


Deliverables (Based on Package):

Clean, readable schematic diagrams (Altium, KiCad, or EasyEDA)

PCB layout files and production-ready manufacturing packages (Gerbers, NC Drill, Pick-and-Place)

Structured Bill of Materials (BOM) with component sourcing links (LCSC, DigiKey, Mouser)

Initial DSP/Firmware architectural setup documentation


Please contact me before ordering to discuss your mechanical constraints, audio power requirements, and signal flow path.
