Hi Laura,

so that the sound doesn't clip? It was fixed, so I don't think that would b=
e an issue.

I think Vicki means that you should always set the gain to a fixed level (t=
o avoid variable gain throughout your recording) and that that level should=
 be chosen so that no clipping occurs (i.e. if the level is too high, the p=
eaks of loud sounds fall outside the recordable range and will be "clipped"=
). Clipping is a problem that  probably has nothing to do with the "silent =
space problem" that you see. To me it looks like a variable gain problem, b=
ut if you are certain that gain was fixed, then I am very curious to hear o=
ther explanations. Perhaps Raimund's suggestion of a compressed audio forma=
t??

If you can, please upload the actual sound file as H=E5kan suggests.

Best, Gabriel
