Reading the Meter
Levels are shown in dBFS, decibels relative to the loudest signal the system can record (0 dBFS). Normal speech at a comfortable distance usually sits between about -30 and -12 dBFS. If the meter barely moves, move closer or raise the input volume in your system sound settings; if it hits the top and shows "clipping", the sound is distorted, so lower the gain or move back.
If nothing registers at all, check that the right device is selected, that the mic is not muted by a hardware switch, and that the browser has permission (lock icon in the address bar; on macOS, System Settings → Privacy & Security → Microphone). Headset microphones often appear as separate devices with "Hands-Free" in the name, which record at lower quality.
Key Takeaways
- Aim for the middle: Speech around -30 to -12 dBFS is a healthy level.
- Avoid clipping: Peaks at 0 dBFS distort; lower the gain.
- Pick the right device: Headsets can expose a lower-quality hands-free mic.
