What is Clipping (Peaking)?
Clipping is a form of audio distortion that occurs when the volume level exceeds the maximum limit the equipment or software can handle, resulting in a harsh, crackling sound.
Why Clipping (Peaking) Matters for Podcasters
Clipping is the enemy of good audio. In digital audio, there is a hard ceiling for volume, known as 0dBFS (Decibels Full Scale). If an audio signal tries to go louder than this ceiling, the tops of the waveform are chopped off or 'clipped.' This results in a harsh, distorted, crackling sound that is painful to listen to and usually impossible to fix completely in post-production. On a recording meter, clipping is indicated by the levels hitting the 'Red' zone. To prevent clipping, podcasters use 'Gain Staging' to ensure their recording levels average around -12dB to -18dB, leaving plenty of 'headroom' for loud laughter or sudden exclamations.
