I have over 200 mpeg-2 files ready for authoring. Some have ac3 some wav audio streams. I want to normalize the audio so that they all play at the same volume level. What's the best method and software to do that using batch feature. I'm assuming the audio needs to be demuxed first, so I will end up with the ac3 and wav files, I have tmpgenc mpeg editor to do that, but I don't know which software can import both formats and then normalize all of them.
