removing background noise on a home made DVD?

[Rudyard]

I was given a DVD of a church service where there is some speeches made by someone who was sick and as such is not very loud.

The camera was set up at the back of the church and there is noise from people outside not associated with the service.

Is there a way to remove the background noise so that I can hear the speech more clearly?

You 'might' be able to improve it. When I want to rebuild a DVD, I use VOB2MPG to extract the whole DVD video to one large MPEG file. Then I open that in VirtualDub Mod and extract the audio to a WAV file. One guide for that: https://forum.videohelp.com/topic280779.html You wouldn't do anything with the video in VDM, you are just using the program to extract the audio.

Then you could use Audacity with the WAV file and try some filtering. Try the High Pass or Low Pass filters. They may work if the frequencies of the voices are different enough.

I'm sure there are other methods, but the above programs are freeware and Audacity works about as well as most other audio editors for filtering. For a quick test, VDM can extract the MPEG from one of the DVD VOBs and then you could convert the audio to WAV and experiment a little.

After this is all done, you would have to re-author the files back to a DVD. You can convert the filtered WAV to AC3 with ffmpeggui, then use that with the VOB2MPG extracted MPEG video in the authoring program.

Not simple, but the main idea is to extract the audio and try to filter it.

Cut everything below 100hz
