    Extract the audio then use BeSweet or any other programs to turn up the gain. Use VirtualDub to mux the new audio together with the original video (Direct Stream Copy) and save.

      3 quick methods

      1. ac3/mp3/wav: BeSweetGUI: check Boost/Compress Dynamic Range

      2. mp3/wav: VirualDub: Audio-Full Proccessing + Volume-adjust volume

      3. with a wav file (uncompressed PCM): drag & drop over WaveUP.exe

      (1 & 3 also normalise audio)

        Success on extracting boosted audio to another file... thanks!
        Still trying to join both files again it requested 48Gb of disk to generate the new AVI! Should I generate an uncompressed AVI before compressing it?
        (its originally an AC3 but i extracted it as mp3 thru BeSweet)

          Use direct stream copy to copy the original video stream without any compression or quality loss.

            Perfect! I got it now how BeSweet and VirtualDub works... I was setting "direct stream copy" for audio (once I was working only on it only) and leaving video as it was (that has "full processing mode" as default).

            Thanks for the help!

            Just explaining for divx-novices as me how it works - maybe this thread turns useful in the future again:
            - this video I was trying to increase volume is a DIVX5.1 video-encoding / AC3 DVM audio-encoding;
            - once VirtualDub doesn't treat AC3 by itself, I used BeSweet GUI to extract the audio to another file, to increase the volume and then to join audio and video again; so:
            - on BeSweet GUI => select input file + select Boost/Compress Dynamic Range + select output type Wave-Stereo or other WAV file (seemed to me that VirtualDub could only join WAV files - if you don't have the associated coded, install it) + click AVI to WAV;
            - on VirtualDub => open video file + select Video/direct stream copy + select Audio/full processing mode + Audio/WAV audio + Audio/volume if want to boost once more + Audio/conversion if want to change it + Audio/compression and select the codec/mode wanted + File/save as AVI.
            ufff... done!

              I did the same thing, except i converted the AC3 file to mp3...

              I noticed 2 things...
              1. The mp3 is much smaller
              2. The video and audio are out of sync after merging them with virtualdub ??

              How can that happen, and what can i do to fix it ?

                All the videos I reencoded sync well... no one had a second of delay

                Don't know if this helps enough:

                - I noticed that when extracting audio direct from VirtualDub (save wave) the result is a file with some seconds of mismatch! (BeSweet does that without time mismatches);

                - exporting to WAV first (BeSweet) minimized the problems when the objective is to convert to mp3;

                - preparing the audio outside of VirtualDub works better than encode audio during the file save... so, encode audio externally and then use direct stream copy for video and audio.

                that's working perfectly for me!
                (just my 3 cents!)

                    Nice to know, Friamannen!

                    btw, I've learned a new thing: when I said "seemed to me that VirtualDub could only join WAV files" I was a bit wrong...

                    It can ONLY join WAV files IF you want to reencode it (full processing mode).

                    VirtualDub will join any kind of file if you have already prepared audio outside it using e.g. BeSweet (direct stream copy).

                    So the better way I found is extracting and reencoding audio to Lame-MP3 using BeSweet and then finally using VirtualDubMod to join original video with new audio (direct stream copy for both and disable original audio stream).
