Xvid audio too quiet!

[honeyshot]

I've always had problems with xvid audio being too quiet, until I recently discovered the 'loud' preset for the AC3 filter, but what about xvids using MPEG Layer-3 (MP3) audio? I haven't been able to find any information or codecs to help me with this problem, and I'd prefer not to have to re-encode the files. Any solutions that don't involve cranking my speakers to dangerous volumes?

matrix mixer might come handy as a very powerful audiofilter

this can be done with the all-powerful 'ffdshow':

download & install the latest version of 'ffdshow' (make sure its the 'celtic_druid' build) from http://www.free-codecs.com

go through start-->program files-->ffdshow-->audio configuration

in the 'decoder' column, set it to 'mp3lib' for mp3. (can post screenshot if confused)

in the left column, tick 'volume', you should be able to amplify it with some of those settings

you could also play around with 'equalizer' too...

I followed your steps and it did nothing. The settings you mentioned were all selected by default, so I tried raising the volumes in 'Volume', which did nothing after applying them. Also, how do I apply these changes strictly for a certain codec or better yet, just for MP3 xvids, since all other audio is at a decent volume level (even playing regular MP3's.)

i just played an xvid with mp3 audio, and it amplified the audio just fine, so its likely that 'ffdshow' is not decoding the mp3 audio on your pc. here's how to make it 'exclusive' to xvid/divx mp3's:

download 'media player classic' from http://www.free-codecs.com

run it, and under 'view', click 'options'. in the column on the left, click 'overrides'. click 'add filter', and select 'ffdshow audio decoder. with then click 'prefer'. click OK. now go back to the 'ffdshow audio configuration' in the start menu, and make mp3 'disabled' instead of 'mp3lib'. from now on, any mp3 played in 'media player classic' should be able to be amplified.

you should also try uncas's suggestion.the alternative is to simply demux the audio with virtualdubmod, re-encode with a program such as 'besweet', and mux it again.

Thanks again, but that didn't help either; however, it wasn't all for naught since I discovered a 'Boost' slider in 'View->Options->Filters->Audio Decoders', which makes the volume much more audible.

but that didn't help either

thats odd, it works for me, i'm watching an xvid right now...

but glad to see it worked out
