AVI Normalize at http://www.vidomi.com/download.php?op=geninfo&did=19 is 3 utilities which extracts the mp3 from avi file(s) and then normalizes the mp3 in MP3Gain at http://mp3gain.sourceforge.net/and last combine avi with the new mp3-file using NanDub. It's all done by executing a bat-file. Now here is the problem! MP3Gain(Dos-version, command-line back end) can not Normalize to a specified level(dB of max volume) so it is automated and can still become clip in mp3-audio. I've tried all dos-commandos available in mp3gain.exe but no success. MP3Gain has a GUI called MP3GainGUI.exe, it normalizes mp3 at a desired dB, so it has more functions. Here is my question: Does anyone know how to edit the bat-file so the MP3Gain GUI handles the mp3 instead of MP3Gain DOS? I've tried to replace mp3gain.exe with MP3GainGUI.exe in bat-file, and when I execute the bat-file it opens the mp3-file in MP3Gain GUI but doesn't normalize it. The source-code for MP3Gain GUI is at the author's website. Anyone with programming knowledge(Visual Basic and C++) and script macro commands (bat-file)! Please Help?!
