Getting a new USB condenser microphone is exciting — you imagine streaming, podcasting, or recording your voice in crystal-clear quality. But the first few minutes can be confusing: “Is it working? Am I too quiet? Too loud?” Normally, testing a mic involves digging through system settings, plugging and unplugging, or using online tools — and that can be frustrating for beginners.
