Audio Clean-up Tips...

[priss]

Hi all, i have a movie here on VCD but the audio is a little quiet and hissy. I was thinking of ripping out the sound and cleaning it up to get rid of the defects and boost the volume a bit.

Does anyone have any advice on what i can do please? I have Sound Forge 6 here but am cautious what to do because it might produce a shorter file or something that will make it out of sync with the video.

Can anyone help please? Thanks. :)

1. search this forum for some threads about noise cleaning.
2. if you'd use BeSweet built-in equalizer, you could go direclty from mp2 to mp2 and would probably end up with the same track length.
3. here's a trivial starting point :
BeSweet -core( -input [..] -output [..] ) -ssrc( --rate 44100 ) -ota( -g max ) -2lame( -m s -b 224 -e )
(lots of mp2 encoders known to produce hiss for 48khz signals, while quality is reasonable for 44.1khz ;))
