Deleting large quantities of dead air

[Road]

Maybe I just don't know how to do this with the current audacity program, but I'm looking for a feature that allows the user to delete large quantities of dead air in between radio transmissions. I work as a dispatcher and make recordings of radio transmissions. Transmissions can be anywhere from 30 seconds to 10 hours or more depending on the type of call requested. Using the delete function in a normal fashion can be very tedious to do, easily causing hours of work for what seems could be done in a mere matter of seconds with the correct programming applied. Am I missing an obvious fix already exsiting in the program or is this something that needs to be added?

One way is to zoom out so you can seea lot more of the wavform - then it's easier to select the dead air with click and drag and then delete it (CTRL+K k/b shortcut).

You can use the fit project to screen zoom button - just be aware that for a largish project this may take a long time.

Thanks.....that process is what we are doing now....however just got email back from the audacity team advising that a new feature for this exists in the beta version called truncated silence....already tried it and it works great, I can highlight a whole section of audio and instantly eliminate all the gaps of silence. Thanks!!!!!!!
