Removing parts creates crackling sound

Hello,

When cutting an audio file, I have observed the following: If I shorten longer pauses or remove mouth noises (with “delete”), a crackling noise usually arises at the point.

This parts is difficult to remove. Sometimes fade out, disabling or amplification to minus db helps. Sometimes I need all the effects, sometimes it doesn’t work at all. Deleting the crackling part creates two of them. :angry: I haven’t found anything about it on the internet. Please help ne on how to remove parts without creating crackling sounds.

To avoid this situation, see Select Menu: At Zero Crossings

To correct this situation, see Crossfade Clips

Thank you, it was really helpful.

Unfortunately, that doesn’t help me with pops within a word. I have a pop filter and the following sample recording is not the typical case of P, B etc. I couldn’t see if it was overdriven during the recording because the interface was out of view. Could that be the cause? It’s very hard to isolate that.

Zooming in very close (Zooming Overview - Audacity Manual)
we can see a discontinuity in the waveform.


Such discontinuities are audible as clicks or pops.

By carefully choosing the start and end points of the selection, we can make a cut after which the waveform is continuous across the edit point:
