Windows 7: Merge Front and Back Stereo channels and output the resulting one in the subwoofer channel

Question

I have a Sound Blaster X-Fi Titanium, and I use the standard 5.1 analog outs on the back of said card.

I am playing Elite Dangerous and have a custom buttkicker gaming chair, but apparently Elite has 5.0 sound, not 5.1, meaning that the basses are encoded in the main front/back channels.

My dedicated amplifier already has a low-pass filter, so all I need to do is feeding it the audio... but at the same time I want to hear it from my surround (analog) headset (a Medusa Speedlink).

Is there any way, software I presume, to combine the output of front+back channels and redirect them on the subwoofer output?

Answer 1

For anyone with similar issues, I have solved the problem with this nice little open-source program called equalizerapo.

The documentation is clean and easy to understand, and I was able to divert all sound channels to the subwoofer out.
