You don't need VirtualDubMod to extract the MP3 from the AVI file. Just use the Extract -> Raw audio in VirtualDub. It'll output xxx.bin, and then all you need to do is change the extension to .mp3.
Awesome. This contributes to shortening the length of my readme solution, which is a good thing (think parsimoniousness):
I've just spent a some time over at the nice and expansive Hydrogenaudio Forums. There, two options were being offered to me:
1) resampling (to unlock vd's CBR encoding) and CBR reencode using virtualdub, but that might, as some suggested, result in audio-quality loss;
2) outputing audio through "file > export > raw audio," video through "audio > no audio; video > direct stream copy; file > save as avi," both using virtualdub, then, secondly, using mp3packer to, "losslessly convert [i.e. without re-encoding] from VBR to CBR, basically just by padding every frame with 0s" (using the same "-b #" as "--ib" prints out), and, finally, remuxing audio (coming from mp3repacker) together with video (coming from virtualdub) to a final AVI file using AVI-Mux GUI.
Thus, needed software:
- virtualdub
- mp3packer
- avimuxgui
