I've done a little bit of comparison work between the new foobar plugin and the older winamp version. While the foobar plugin is nice, since it does the work of splitting the LFE and surround channels for you, I found that it does not attenuate the surrounds. This leads to quite a bit of clipping.

I got much better results using the methods posted earlier in the thread with Ozone 5.

On a different note, I think we've always assumed that there should be a 3dB attenuation in the surround channels due to the DTS post production literature.

Here's the studio setup info from the pdf:

To me this also suggest that the LFE should be boosted by 3dB. However, whenever I tried that, it seems wrong. I'm just curious if anyone else has an opinion on the LFE levels.
