I have an mp4 video file, where the audio is too loud in comparison to most of my avi's and mpgs, I've had no problem in the past adjusting audio levels and am reasonably familiar with VirtualDub, but don't have anything in my toolbox to handle an mp4 video file.
Yamb says this about the file:

Can anyone point me at a tool that would be able to adjust the audio gain on this file?
Or a pointer to a guide or faq that would cover this topic.

Could also try aacgain once you have extracted.
I downloaded BeSweet and BeLight, pulled the Nero DLLs off the Nero disk I received with my burner, spent ages browsing the net trying to find some of the other dlls BeLight seems to require.
Extracted track2 using Yamb and tried to use BeLight 0.2.2.0 beta 9 to convert to Wav, BeLight crashed after writing a 36k Wav, the mp4 audio is 42M.
Tried using Mp3GainGui after renaming Aacgain and I get:
24/02/2007 18:31:06 Error while analyzing: C:\Data\Movies\Track2.mp4 is not a valid mp4/m4a file.
Vlc has no problem playing the original file or the extracted Audio mp4.
Any pointers as to what to try next?
Thanks Soopafresh, that did exactly what I wanted.
In that case to celtic_druid
Now I just have to understand what the options do
