Programm for fixing AC3 CRC

[DreckSoft]

I have an AC3 file here with dialog normalization set to -27db so I hear nearly nothing. All other files I have from the same source (TV-Recording) are set to -4db so I tried patching the AC3 headers (replaced them with a hex editor) but now the CRCs are incorrect. Any1 knows a programm which just rewrites the AC3 CRCs?

BeSplit is a fixing tool, i dunno if it corrects CRC, though.
BeSliced is GUI for BeSplit.<http://dspguru.doom9.org>

I tried this one already but it seems it only discards frames with wrong CRC :(

Just a suggestion..

Why not use AC3machine and set a gain acording to your needs and re-encode ? No need to patch ac3.

Since the file is 100% OK except for the wrong header reencoding is the last option I want to consider. I think it's possible to rewrite the CRCs, I've just not found the right program. But thanks anyway for the suggestions.

Seems I need new glasses. BeSplit 0.9b6 has an option -fixcrc
Works now!

Thanks DreckSoft, for reporting back. I didn't know that it was possible to fix CRC.

Thank you:)
