I don't always have occasion to look at my csound
output in a sample editor, but a while back I did.
I loaded a sound which was a dense blast of tiny bell
sounds that I made with a granular technique in the
score generator.

The wave looked funny.  It had a huge sine-like
offset in it running at maybe .2 Hz.  It made the
sound look like a serpent in the editor, rising
above the origin, then below, and so on throughout
the duration of the sound.

I looked at other sounds, and found that this was
not uncommon, perhaps due to my habit of spraying
small samples across the score as if from an aerosol
can.

I went back, and added 'dcblock' lines to the 
important orcs, and this really fixed things up.
Now the individual sounds, and the entire piece
look entirely symmetrical with respect to the zero line.

The reason that I mention this, is that I was having
a problem with sound output from my amplifier that
I was attributing to hardware.  The problem was that
I would notice an analog sounding, popping distortion
in my piece, that I believed was not due to the content
of the sound.  The distortion was not present at very
low playing volume, but I knew that I was not near
overdriving any of the pieces in the audio chain.

This distortion seems to have disappeared since the
introduction of the 'dcblock' lines.  It makes sense
to me.  There is only so much signal that a capacitor,
or a speaker cone can take in one direction.

I just thought that I would convey my experience to 
the list, as I now consider the 'dcblock' opcode to
be a sister of 'outs'.
