<div>> I think osc~ will fold over correctly... however, to hear 150 Hz. you</div>
<div>> would have to tune it to 44250 Hz (or indeed 43950), not 22200 which folds</div>
<div>> over to a (still inaudible) 21900.</div></span></div>

<div>> think that when one plays a 22200 freq at 44.1kHz sample rate, you</div>
<div>> will hear it as 21900 rather than 150. To reach 150, you have to go</div>
<div>> up higher to 43950 (= 44100-150).</div>

<div>> That's because the example you give here isn't an example</div>
<div>> of the Nyquist theorem. The aliased frequencies 'fold back', rather than</div>
<div>> wrapping. It is like the Nyquist frequency is a mirror reflecting the</div>
<div>> signal's components back into the sub Nyquist range</div></span></div>

<div><br># Thank you very much! I forget that the problem of sampled discrete signals is called "foldover", I thought that was "wrapping" like Jamie said. Sorry to keep you busy with my ignorance. (But on the way of investigating my problem, I learned much about controlling objects pricely.)

<div>> I wonder, which other objects would also benefit from becoming<br>> "special" in the way, vline~ is special. A possible model could be<br>> t3-lib, but for example the t3_bang object already is there in the
<br>> form of the normal bang message, when its origin is a clock-derived<br>> message (as sent by metro etc.). So we don't need a "special" bang<br>> object. t3_bpe is the same as vline~ basically, t3_sig~ too, t3_metro,
<br>> t3_del and t3_timer are the same as metro, del and timer now.</div>

<div># Thank you for the info about t3-lib! [t3_metro] object is absolutely what I need. It's period has not a minimum acceptable value like [metro]. Their documentation is a bit awkward, but I figured out how to use it.
