Make the volume higher on a divx.

[myph]

I ripped a dvd using xmpeg, but the volume is really, really, really low. if I turn up the volume all the way on my speakers and in windows, then it's barely sufficient to be able to hear it, but then my computer makes a some kind of sound (I got an e-mail or what not), and my speakers are practically getting blown.

I would assume that what I would have to do is rip the sound off the divx (split into two files), then adjust the mp3 volume higher, then recombine them. Does anyone know what software I need to do this? or is there an easier way? Thanks

it seems that you have not normalized your sound. doom9 provides several audio conversion guides also covering normalization.

there is a way to normalize your sound subsequently, presupposed it was encoded to mp3:

1. open your avi in nandub and select "save wav..." to save the mp3 stream to an extra file. rename the file to *.mp3.

2. use mp3gain to normalize the mp3:
click on "radio analysis". after analysis is done,select "modify gain/apply max noclip gain".

3. in nandub set audio and video to "direct stream copy" and add your modified mp3 by selecting audio/(vbr) mp3... now press f7 to save the new avi.

Where can I get this mp3gain ?

Use the DeDyanmic filter in PowerDivx, BSplayer or ZP. We just had a post like this in the forum.

Didn't find it there. But for anyone interested I found its homepage:

Matthias Lenk's DeDynamic audio DirectShowFilter will only allow +6 dB amplification without dynamics compression, but of course this should help a lot. PowerDivX 3.12 comes with it plus it will allow easy access of the filter in a DeDynamic config page.

Anyway, in this case it really seems to be better to demux the MP3, use MP3Gain on it and mux it again, as +6 dB may not be enough here ....

You can use BSPlayer with an AGC Winamp plugin, for example "TomSteady Automatic Gain Controller", and put it in the plugin directory of BSPlayer...
