Making outline
- Assemble electrical stimulus/amplifier, calibrated microphone, quiet specimen fixture and actual sampled acquisition/physical host
- Detailed procedure and acceptance remain unresearched.
What remains unresolved
- Making route and target-level requirements not researched.
- Current memory-first method needs source and compatibility review.
