Project Demux Normalize and Remux

[Teta]

I have several hundred short Podcasts and You Tube files with extensions of .wav .mov .wmv .mp4 .m4v which need to be recoded for multiple devices, namely Zune, Walkman & Roku.

First, I need to demux them to normalize the audio and then remux them in batch for further conversion. The easiest way I found was to recode them to mpeg-2 with Pazera 2-pass, use batchdemux0.14 to demux, and run the files through Audacity for normalization and remux them with ffmpeg. The problem is Audacity batch only outputs in mp3.

I can demux them with ffmpeg and set the audio output as .aac but when I look at the instructions for aacgain_1_9 to get it to work in Windows, my head starts spinning. I tried that trick to install mp3gain and rename the aacgain.exe to mp3gain and drop in in the mp3gain folder but that doesn't seem to work for me.

Note -- my ffmpeg scripting skills are limited.

The bottom line is am I worring excessively about multiple recoding and possibly degrading the output since these are crappy little files and not HD surround Sound movies where quality really matters?

Never mind. I figured it out. It's somewhat convoluted but it works.
