We have an application that triggers recording when it detects 0dB in a recording for a specified time. We have a lot of existing voice recordings where either the dc offset correction has resulted in each phrase being separated by 0dB or that is how the original recordings were created with no background noise. Any ideas on how to search and replace the 0dB sections with a very low level signal?

Re: Replacing silence
By "0dB" I assume you mean silence (0dB actually means full blast in the audio world, following standard convention).
Audacity has a silence detector, but I've never had great luck with it.
I have no idea what kind of project you're working on, so this is just a shot in the dark: The best I can say right now is that you can probably add a very small "room tone" to everything you've got and get away with it.
What exactly are you trying to do?
