Developed 6 Layer PCB for measuring audio degradation in Tesla vehicles during environmental testing. Owned all schematics, layout, and firmware. Unfortunately due to NDA reasons I cannot share a lot of information.

• Owned 6 Layer PCB schematic and layout

• Samples 12 channels at 96KHz simultaneously using DMA

• Designed Ethernet schematic and layout

• Variable emulation of speaker impedance 

• Wrote software to receive stream of audio over ethernet and run FFTs in real time to see degradation of specific frequency bands over time
