Hallo!
As the others already said you should at least use a highpass to remove the DC ...At least? Other things I should run it through?
Well, you could also a limiter+etc. - but I think the biggest problem is the DC offset ... Because if you have no DC-offset you will here when it is too loud and can decrease the volume ...
We once played with PD until all the loudspeakers were (unfortunately) damaged ... ;):-(
But it was funny :) LG Georg
