[Discuss-gnuradio] Removing DC offset

[Patrick Strasser]

Hello!

I'm playing around with audio as source/sink (hope to produce some nice,
sensible and usefull examples), but I'm stuck with a problem:

What is the best way to remove DC offset?
FIR seems not sensible, as you need a huge number of coefficients to get
 steep slopes.
Is there an easy way with IIR? (I'm not familiar with IIR)
