Capability requirements and tolerances
Consumer-specific numerical targets, quantities and acceptance limits remain open or incompletely reviewed. No smartphone-grade suitability is claimed. Distinct capability tiers require their own making route and qualification.
Parts and Tools needed
No researched inventory yet. This is an unexpanded frontier; an empty list does not mean the item can be obtained directly from nature.
What remains unresolved
- Manufacture, quantities, suitability and complete inventory remain unreviewed.
Canonical reuse assessment
"Separate acquisition electronics from microphone head preamplifier; no software filter substitutes for pre-sampling alias control. Noise/linearity/bandwidth requirements open."
