[CM] Finding (and deleting) gaps with snd

[Rolf Steinort]

Hi,

I use snd to edit recorded audio streams. I am stuck (due to LISP 
illiteracy) with one problem:

>From time to time there is a gap in the sound, a small time with only 
zeroes. Now I look for them, but there must be a better 
solution.... :-) I mastered to search for one zero, but that isn't 
really helpfull.



My question: How do I search for more than one zero in a row? 



Luxury question: How do I search for these zeroes and replace them with 
nothing?



Thanks for reading this far!

Rolf
