Cameras and audio calculator
Audio-interface I/O planner
Musicians matching inputs to simultaneous mics. The decision this page isolates is narrow on purpose: translate input count into an interface class. Payload, channel count, and distance decide the class. A sample photo does not.
This page produces an explainable category or size so options can be compared without a product ranking. The calculator does not rank Focusrite, Universal Audio, and Solid State Logic. It produces an explainable class so Focusrite Scarlett 2i2, Universal Audio Volt 476, and SSL 18 can be compared as examples of that class.
The working method is: Convert the inputs into a published planning class using the method on this page, then compare official product pages that match that class. Planning notes are grounded in CTA. This page does not quote a price or rank a brand.
