Program to amplify AC3 track?

[kartakis]

I 've desided to make some Divx avis using the original Ac3 sound from the disc. I 've demuxed the sound saved it as .ac3 file and muxed it back in the end. The avi was ok but the sound's volume was too low.
Is ther any program which can amplify the ac3 file without the need to decode the tracks from Ac3 to Wav and re-encode them after amplification?

Download PowerDivX 3.12 player from Doom9 download section or www.powerdivx.com, and activate the 'DeDynamic' audio filter ... set amplification to +200% ( 6 dB ) ... this should help a lot !

Still dreaming of a waveboooster.ax :D ... Ligh ?

I'd really like to... I'm sometimes trying to implement the WaveBooster technology into some kinds of plugins, but it's not as easy as I would like to have it - the worst detail is that everyone uses C++ except me, I'm holding the Delphi flag upright.

My first try to create a WinAmp DSP plugin was a desaster, always crashing and doing crazy things, unable to debug it... I recently found another SDK and will try to use that one. The whole DirectX SDK might be a bit too much, I'd need the required API only.

Another big problem is the resulting size - Delphi is a RAD tool, therefore the created files might be a bit large if they use any window; currently I need the Forms unit to do that, I don't know how to do that without Forms (it will probably become much more complicated). I'm thinking about a shared GUI DLL for any kind of plugin (WinAmp, DirectX, VST, CoolEdit), but this may give problems with live parameter changing and pre-listening functions...

Also I have more ideas to enhance the functionality. Hope to be able to publish something soon, but no promise...
