Slight differences in noise levels between 2 clips can cause a click at edit points. If you apply a 2 to 4 frame audio fade the click will go away. Some DAWs force an edit at “zero crossing” points. That’s the point in the file where the audio waveform crosses zero. Edit there and no click. I don’t know of any NLE that does that automatically. But, applying a fade smooths the transitional gain so no click.
