Which of the following chops off the audio waveform?

(A) Clipping
(B) Limiting
(C) Compression
(D) Amplification

(A) Clipping

Clipping occurs when the amplitude of an audio waveform exceeds the maximum level that a system can handle. This results in a flat, chopped-off appearance of the waveform, as the peaks are cut off or “clipped” to match the maximum allowed amplitude. This can lead to distortion and a harsh sound. In contrast, limiting, compression, and amplification generally involve controlling or adjusting the dynamic range or volume of the audio signal without necessarily chopping off the waveform.
