I spend most of my day on video calls, and I own several microphones: my laptop mic, a webcam, a USB mic, a headset. I never knew which one sounded best.

How Do U Sound? is a free microphone test that runs in your browser. It records a short guided sample from every input at once (you talk, whisper, then clap), then scores each mic on signal-to-noise, noise floor, room echo, and plosives, ranks them, and lets you play them back side by side.

Your audio never leaves your machine. There is no backend; all recording and analysis happen client-side.
