microphone
Let an agent explain microphones and how they work, relay types, polar patterns and applications from audio engineering sources, describe the products the registry aliases name, and distinguish microphones from loudspeakers, pickups, hydrophones and audio interfaces.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain microphones and how they work, relay types, polar patterns and applications from audio engineering sources, describe the products the registry aliases name, and distinguish microphones from loudspeakers, pickups, hydrophones and audio interfaces.
A transducer that converts sound into an electrical signal, used in recording, broadcasting, telephony, public address and measurement, in types such as dynamic, condenser, ribbon and MEMS microphones, with directional patterns from omnidirectional to cardioid and figure-eight, and products such as the Rode NT1-A condenser, Rode NT-USB and NT-USB Mini USB microphones, the Royer SF-24 stereo ribbon microphone and the historical STC 4021 ball microphone; the registry also classes microphones as sensors and, loosely, as musical instruments.
What it is for: Capturing sound as an electrical signal.
It can be explain principles; relay types and patterns; describe products; distinguish related devices.
Distinguishing features
Transducer
Several operating principles
Directional patterns
Wide application
What it looks like
A handheld, stand-mounted or built-in capsule, often with a grille.
Physical character
invented: 1876-1878 note - Berliner, Edison, Hughes
Neumann U 47: 1947 year - landmark condenser
polar patterns: omni, cardioid, supercardioid, figure-eight list
Rode NT1-A self-noise: about 5 dBA
How it is recognised
Sound-to-signal transducer
Dynamic, condenser, ribbon and USB microphones; omnidirectional pattern; Rode NT1-A, NT-USB, Royer SF-24, STC 4021
Loudspeakers do the reverse; pickups sense vibration; hydrophones work underwater; interfaces convert signals

- How should audio engineering sources be linked?
- The registry entry has merged aliases naming specific products; should they be split off?
