Downloaded DIVX has way too soft sound.... What can I do?

[lucas]

I downloaded some DIVX movies from the web, but the sound is almost unhearable. The coder probably didnt amplify the sound or something.

What programs can I use to amplify the sound myself?

Thanx!

there's a volume knob on your stereo ;)

dedynamic or the tfm audio filter are generic purpose audio gain tools, and powerdivx directly incorporates dedynamic if I'm not mistaken.

The real problem is that your music mp3s are way too loud. :angry:
Record companies are trying to let their cds sound louder and louder, but for what reason??? beats me.

Hi,

I used to have the same problem with DivX rips I made then I discovered Dynamic Range Compression. Basically when you play a DVD the player will do this for you automatically, but DivX's don't do this for you.

I used to use DeDynamic to take my quiet audio audio and compress the dynamic range before putting the audio basck with my video stream.

There is another way that means you don't have to mess about with the steams at all! :D Go to www.doom9.net and in the software section look under audio for the DeDynamic filter. Download it and follow the instructions in the help file for how to install it.

Now download BSPlayer (also from Doom9.net), set it up and run it. Open settings (right click in the player and select the options menu then settings). In the audio section make to tick "use dedynamic filter". Now open your video file and right click on the videos output and form the menu that pops up go to properties and click on dedynamic. Leave the normalisation at 100% (basically if you set this to high the loud parts will pop and crackle really badly). Use the dynamic amplification slider to increase the volume to the level you want it at.

EASY!:cool: Now all you have to do each time is to play you movie in BSPlayer and adjust the dynamic amplification accordingly.

Hopefully the DeDynamic filter will be incorporated in other players soon. As doom9 mentioned powerdivx also supports it, but I haven't tested it and besides I prefer BSPlayer!

Hope that helps!

As a side note: It would be nice if there was a way to predetermine for each audio stream what level the dedynamic filter should be set at (some kind of header for example). I hear the people who make DivX are working on a new format so hopefully this could include something similar as well as holding subtitles in the same file as well. Anything to make the conversion all one process that can be left to run overnight would be appreciated.

If the sound is soft due to the lack of normalising, and the audio stream is MP3, you can demux the MP3 from the stream, use mp3gain to normalize the mp3 without reencoding, then mux it back again.

PowerDivX 3.12 is maybe a bit old now but its still a wonderful player, and as Doom9 was pointing out, you can directly access the Dedynamic filter from the config page, no need for download, installing, etc. ... its coming with it !!

Also .... PowerDivX4 is going to be public beta soon :D .... more info on www.powerdivx.com !
