The motivation for this is: I have a hardware DAC
(digital audio
converter) in one part of my house, and a subwoofer in another.
There is a single coax run between the DAC and subwoofer, so I can
only send one channel. If the overwhelming majority of my music has
the bass mixed equally, sending only one channel isn't a problem.
But if I choose the "L" channel to send to the sub, and much music
has the bass mixed only to the "R" channel, then I won't be able to
hear the low frequencies. I want to find out how often this might
happen.
Bass is almost always mixed to the center as low frequencies are
omnidirectional. If you only send the L or R channel, you'll lose
some of the signal strength (about 6dB if I remember correctly) and
the subwoofer won't have the "oomph" it should, but since you'll need
an amp after the DAC anyway you should be able to make that up easily.
That said, if you're listening to old Beatles stereo mixes, the bass will
only be on one channel (left, usually) and if you've sent the right to the
DAC, there's not much for the sub. I'd try and convert the signal to mono
for the sub feed.
