increase the sound on an iso or dvd

[py52126]

Hi,

I have an iso file that needs an increase in sound. The video is fine, but the sound needs to be at 100% just to watch on my laptop. Is there any way to increase the sound on that iso file?

Extract the content, demux the audio, process the audio to increase the volume - an increase of 6dB should double the current volume - then re-encode the audio, remux it back with the video, then put it back into the DVD structure and create a new ISO.

So possible ? Yes. But quite time consuming.

Are you sure you have checked all the available volume level adjustments ?

I have yet to hear a laptop that played audio with any decent volume or quality!

I bought a cheap pair of $20.00 sony headphones for my laptop and it was an improvement of about 100X!!!

Or buy an external amplified pair of speakers.

Thx,

I will give the demuxing a try.

You might try simply installing AC3Filter, and seeing if that helps (and experimenting with the settings there, if necessary).
