extracting audio from movie

[flymo]

I have used various tools to extract the audio from a movie file I have. Every time I do it, the audio comes out VERY quiet. However, whenever I play the movie in KMP player or VLC, it sounds nice and loud?

Am I doing something wrong? Is KMP or VLC applying massive amplitude? Seems very unlikely..

Thanks

How do you extract it? Just demuxing with demultiplexers or converting to wav,mp3,etc?

What kind of of audio? AC3?

[flymo]

yes, I am not very familiar with the settings I need to apply, but I am extracting to .wav, not sure what type of audio it is in the movie. Its Xvid.

[flymo]

have tried with audiograbber, filefactory.. always the same result, comes out VERY quiet.

[Baldrick]

Use mediainfo to check what kind of audio.

And what do you convert it to wav with?

I would just try demux the audio with for example Pazera Free Audio Extractor. Or convert to wav and boost the volume in the converter. I think pazera can do that also.

Thanks for replies.

I am in Panzera now but I cant see any option to demux? I tried exporting to 300% volume but its STILL quiet and just has loads of hiss

Under output format choose: Try extract original audio stream.

aha, I think we are getting closer to solving. I've rarely heard about a 48k mp3?!

got you stumped as well? ;( I will try and find another copy of the movie file which hasn't been ripped so confusingly.

No. Discussion about WAREZ is not allowed here at VideoHelp and nobody will continue this conversation.

Buy the DVD.

[Baldrick]

Yep, buy the dvd and rip the ac3 audio.

I don't know about KMP but I'm pretty sure VLC's maximum audio volume is 200%.

48k MP3 is perfectly normal if it was encoded using a 48k source, which most soundtrack audio is.

Try using VirtualDubMod to extract the MP3 audio. When you've opened the AVI, use the Streams/Streams List menu, then the Demux button in the Window which opens.
MP3 audio can have it's playback volume adjusted without re-encoding. MP3Gain will do it. By default, MP3Gain has it's normalizing function disabled so you'll need to go into it's settings and enable the normalising features first. Or try MP3DirectCut. It'll normalise MP3 audio too.
