Batch normalizing 1000 tracks and batch 0.3 silence at start and end of each

[get known]

Working on a project to help Tsunami fund raiser in Japan.
1. I have 1000 tracks that have special names. I need to mass normalize all of them to -3db and then save as their original name. Is this doable?
Possible in adobe audition 3 that i am trialling?

2. All tracks have 0.6 silence as the start and end but I need all of them to have 0.3 seconds. Any possible way to do this in one big go?

Appreciate your help.

I just tried in Audition 3 but it sends the levels off the charts. I have to select file by file. Wonder if there is a way to do a a group normalize but normalize respectively within each tracks levels.

OK I made up a short cut key for normalize and I click on each track and it takes maybe 5 seconds per one x 1000 of these files. Seems the best way so far. Would love to know how to add an automatic 0.3 seconds silence at the start and end of each track.

With bash and sox, very possible.

Although normalize isn't always normalize. i.e. Stereo tracks, do you want to treat each track individually and normalize different amounts on each, if they don't already match? Some content might favor one or the other side, but not both.

If you know for sure that they'll ALWAYS have 0.6 second headers and trailers, you can convert to a raw format and trim the bytes, then convert back to a non-raw format. No actual format conversion is done per say. It just strips off meta data and headers when you go to a raw format. At which point you can mathmatically calculate bytes to chop / extract. Since every byte is DATA, not fluff. But that's probably overkill and you might want to keep headers and ID3 tags and such. Which even a batch-able software package could end up discarding with no batch-able work around.

Thanks for the feedback. Wanted to treat each track individually. The 0.3 seems tough to do. I'm dreading editing 2000 tracks by hand.
