[pulseaudio-discuss] enable-lfe-remixing

[David Henningsson]

Hi,

As you might know, I'm trying to make life a little bit easier for 
laptops with a built-in subwoofer.

Part of that is to revisit our "enable-lfe-remixing" setting, which is 
currently disabled by default.

This means that people playing back stereo material, will, by default, 
complain that their speakers sound more tinny than on Windows.

1. I understand that there might be reasons we have it disabled by 
default, but it would be good to have those reasons lined up. What are 
those reasons really?

2. Should enable-lfe-remixing be a global setting? Or should it be 
configured per port? Per profile?

3. Should it happen that I will end up having to write a low/hipass 
filter for properly separating LFE from main speaker frequencies, what 
are your recommendations? I don't think we have a module we can use, but 
are there finished implementations in libraries that we can just try to 
import into PA? Or do we need to start over from scratch? Has anybody (e 
g Alexander) done any research on this topic?
