Enhancement: Support >2 channels and LFE

[tolnaiz]

Many people have an analog 5.1 / 7.1 setup where the ".1" is a separate audio channel for the subwoofer. Unfortunatelly if you play stereo music, it plays only on the front speakers.

On some Creative soundcards you have the option to redirect low frequency components to the LFE channel. You can even select a cut-off frequency. However, many cards doesn't support this, some don't even have any configuration panel for macos.

I think this would be a very useful feature for this app.

You can see the UI interface for this feature on this picture:

I am triaging & trying to fix all open issues before release of eqMac v1.0.0. Excuse the wait.
Yes currently eqMac really supports only 2 channel audio. This is something to address in the future!
