editing/filtering dvd-r audio files

[dlntx9]

Hello all,
this is my first post to the forums. Hopefully someone here will be able to shed some light on this for me. this is the situation.

I have a number of vhs tapes, most of which are home recordings. They all contain an undesirable amount of hiss. I recorded the vhs tapes to dvd-r using a panasonic stand alone dvd recorder. I then transferred the dvdr files to my harddrive, so that I could make multiple copies of the dvd-r. I have a sony internal dvd-r recorder, and use nero for burning. What i wanted to do was run some sort of filter on the audio file of the dvd-r. I have sound forge and a few other audio progs, but none of them can open any of the vob files on my disc/hard drive. Is their any way to edit these files? Would I be better off just buying some sort of EQ hardware and have it set up between my vcr and dvd recorder, or is it possible to edit the audio portion of a dvd-r file copied to a harddrive. Any help on this would be greatly appreciated.

Hi! and welcome to our forum!

You can demux / split the audio from the dvd using pgcdemux.
Edit it with sound forge, export to pcm wav or ac3.
Remux / add back to the new audio to the dvd with muxman and you can keep the same menu structure.

There's a lot of methods you could use. I use VOB2MPG to convert the DVD to a single MPEG-2 file. Then I demux or separate the audio from the video. It would depend on the audio format, but you then put it into a audio editor and apply filtering as needed. I use the freeware Audacity. It accepts WAV audio, MP3, Ogg and AIFF. After filtering, I output as WAV, then convert the audio to AC3 with ffmpeggui. I add the MPEG-2 video and the new AC3 audio to TMPGEnc DVD Author and make menus, etc., and author to the DVD format, then burn to DVD.
