What does audio meters turning red indicate?

• A. Overdrive
• B. Silence
• C. Clipping
• D. Distortion

Answer: (C)

Red on audio meters shows the signal has hit the maximum level the system can handle. In digital audio, that ceiling is 0 dBFS, so when a peak goes above it, the waveform gets cut off—this is clipping. Clipping creates harsh, unwanted distortion because the tops of the waveform are being truncated, introducing extra frequencies and an unpleasant sound. This is the specific situation the meters are signaling when they turn red. Silence would give no reading at all, and while distortion can occur for other reasons (like come from a saturated effect), the red alert is the indicator of clipping due to overload. If peaks only flash red briefly, you may not hear a problem, but continuous red means you should lower gain, reduce input level, or apply limiting/compression to keep peaks within headroom.
