What aspect are you trying to modulate? If you are recording at a given sampling rate and bit depth there is no aliasing inherent. Aliasing occurs from fx processing, conversion and downsampling etc.

yes, i was thinking about downsampling, cause it deformates signal in some way, my question is, could you set specific downsampling rate which generates/modulates interesting sound form which could be used in some sound processing?

Aliasing is not interesting. It hurts my ears with the digital pops clicks squeaks etc. If you were to downsample with NO anti-aliasing you would get something probably but I don't think it would be interesting.

Ok, thanks for answer, was just curious about that.
