Increasing the volume of an AVI file?

[Kelemvor]

I have a clip from TV that the sound is really low on. I have to crank up WMP to the max and turn my speakers up almost to the top as well. Is there some way to re-encode this file while not changing the video at all but just upping the volume?

If you use VirtualDub, you can extract the sound as a WAV file (uncompressed PCM), then edit that/ raise the volume however you'd like, then put it back together. You can choose the encoding mode for video and audio separately, so you can choose "Direct Stream Copy" for the video, but "Full Processing Mode" for the audio, then choose your edited WAV file as the source, choose any audio compression you want for the new file, etc etc.

lookup 'gain'


easiest way would be in vlc, go to preferences, click 'show advanced options' at the bottom right, go to liek the third option for audio and increase the global gain from the feault of '12'

You can change the volume in VirtualDub without having to extract the audio, IIRC. You need to set "Full Processing Mode" for the audio and add filters to the graph.

it depends on the codec though.
