can someone please explain tp me how this is possible? an what use it may be to create insane lookin waveforms like this?

looks like some mean dc offset.

from http://en.wikipedia.org/wiki/DC_offset :

"DC offset is usually undesirable. For example, in audio processing, a sound that has DC offset will not be at its loudest possible volume when normalized (because the offset consumes headroom), and this problem can possibly extend to the mix as a whole, since a sound with DC offset and a sound without DC offset will have DC offset when mixed. It may also cause other artifacts depending on what is being done with the signal.

DC offset can be reduced in real-time by a one-pole one-zero high-pass filter. When one already has the entire waveform, subtracting the mean amplitude from each sample will remove the offset. Often, very low frequencies are called "slowly changing DC". While not technically accurate, a high-pass filter can remove such a "changing offset" better because its cutoff does not extend to as low a bandwidth as the above method."

Tom cosm posted some nice DC Offset waveforms up not too long ago

i love waveforms! made some quick screen shots.
not the craziest ones out there, but just to keep the ball rolling.
(got to dig deeper and get out my collction of recorded recording errors)
pictures are too big, but who cares?





my favourite snare:

found these...


from ploguesounds...different recordings of a certain sid-sound...
