Subject	[Csnd] Strange waveform?
	Hello, I am using the chebyshevpoly opcode (see below) , and I wonder if my instrument is acoustically viable. I like the sound, it is great for me, but the waveform (screenshot) is not spread around zero. http://csound.1045644.n5.nabble.com/file/n4531610/firsttrack000.png 1. Is it really a problem? 2. Does a solution exist to solve that? Thanks!

	Yes, that can be a problem when mixing or sending sounds through non-linear processes. Try running it through dcblock or dcblock2: http://www.csounds.com/manual/html/dcblock.html http://www.csounds.com/manual/html/dcblock2.html Either of those should get it centered around 0. -- Electronically, Jeff Taylor On Tue, Jun 28, 2011 at 7:31 AM, obaudouin <olivierbaudouin@gmail.com> wrote: Hello, I am using the chebyshevpoly opcode (see below) , and I wonder if my instrument is acoustically viable.

	It works very well with dcblock2.
