Separate an indicator from an effect
Audacity waveform documentation describes a clipping view which marks columns containing full scale samples. It also states that enabling the view changes the drawing rather than the audio. Therefore a newly visible field of markers does not mean that turning on the option damaged a previously clean recording. Equally, hiding those markers does not remove distortion. Keep the display option distinct from any processing subsequently applied to the sound.
Check the same passage at a useful zoom
For an original exercise, use a permitted local recording and compare one troublesome spoken word with the clipping view enabled and disabled, leaving all processing unchanged. Then zoom in on the relevant section instead of treating a distant peak envelope as a picture of every sample. Record what was heard and what the indicator showed. The display can help locate a problem, but it does not alone establish how an earlier capture or conversion produced it.
Preserve the original before experimenting
Lowering later playback volume may make a distorted passage quieter without recreating its lost waveform. If the source can be recorded again legitimately, correcting the capture level can be preferable to relying on restoration. Keep any processed attempt as a separate output and compare it with the original. This article reports no restoration test and promises no recovery of missing detail. Its purpose is to prevent a visual diagnostic control being mistaken for an audio repair operation.
