What this mic test measures
Peak shows the highest instant level. RMS is the average loudness over time. Aim for strong RMS without constant 100% peaks. If peaks hit 100% and the sound distorts, lower sensitivity or move the mic farther from your mouth.

Keep troubleshooting
- Eject water from speaker if the sound is muffled after a splash.
- Run the speaker test to check for distortion, rattles, or imbalance.
- Try a quiet room and move cables/adapters—ground loops and loose jacks can cause hum or buzz.
- On Windows or macOS, open system sound settings and ensure the correct input is selected and not muted.
