The easiest way to do that is to use a high pass filter set to a very low 
frequency. A low slope like 6 dB/octave is fine.

If you do much editing, you want zero DC offset so you don't create 
transients or thumps when you cut and paste, or change levels or add 
fade-ins or fade-outs.

It is normal for musical signals to be asymmetrical. That is because music

and voice pretty much always contains even harmonics. There's some math 
behind this that makes it always true.

Lots of even harmonics make waves asymmetrical. All even harmonics give
you 
a wave that has either the upper or lower side completly cut off. Now
*that* 
is an asymmetrical wave!
