Everything on Mic or Room in one place: 3 pages, grouped by what they help you do, newest first.

3 inputs, instant result
Test your mic with three numbers: noise floor, speech-to-noise and clap echo (RT60). Pass and fail lines for Zoom calls and podcast recording, each with its reason.
9-row table
Why an online decibel meter shows negative dBFS, how browser auto gain skews it, and a 60-second pass or fail check of your room before a call or recording.
