Okey dokey, this turned into quite the information chase for me and i learnt a bit.
The info below is only useful if you have these Zalman 5.1 headphones, 5.1 soundcard, want to use ffdshow audio and decoder filters and (optional) to upsample stereo anything up to 5.1 and playback thru your 5.1 headphones.
My question about LFE ? Answer - LFE removes low bass frequencies from front speakers and routes them to the back woofer and the Zalman headphones handle this easily with the right codec/filter setup.
ffdshow audio decoder settings
Codecs - mp3 -mp3lib and whatever else you want ffdshow to filter)
Mixer - 3/2 5 channels, LFE ON, normalize on, Voice control ON, Expand stereo ON
Volume - Normalize ON at 500%, Show current volume levels ON
LFE Crossover - 80, 2.0, Remove low freq... ON
Delay - 20ms (makes the bass more noticeable at the rear speakers)
Output - 16 bit ONLY !!!, connect to Direct Sound ON
And that's it ?? ...
You need a player that can use ffdshow decoders for audio or video. I now use Zoom Player lite for audio and have used Media Player Classic for video forever (or maybe longer)..
Testing - I left ffdshow volume controls at default as I read listening per channel is not the way to test surround when upsampling. I played with LFE and bass delay till that sounded OK. I used boring test samples d/l off the Net and sometimes a wav or mp3. I used Mariah Carey "Emotions" for treble/clarity and most songs by Rammstien distort like heck until you get LFE and the bass stuff sorted.
That's it. The LFE and bass still need a lot of work but that's all personal choice.
Any feedback or information welcomed.
