(((# My ultimate aim was producing a pure sinusoid at a frequency of, say at 22200 Hz, and here it as it were 150 (= 22200-22050) Hz. in order to make an example of Nyquist Theorem. I first tried to use the osc~ object but it didn't give the result I expected. (first, I have to figure out why you have used a table which includes a sinus shape which have more periods than one, in the C1.nyquist.pd) I came here from there with the intention of using a tableosc4~ instead of osc...)))
I think that when one plays a 22200 freq at 44.1kHz sample rate, you will hear it as 21900 rather than 150. To reach 150, you have to go up higher to 43950 (= 44100-150).
