I think of squares as superposition of sines. -----Ursprüngliche Nachricht----- Von: gareth.whitcock [mailto:gareth.whitcock@ntlworld.com] Gesendet: Freitag, 16. Dezember 2005 21:21 An: Loopers-Delight@loopers-delight.com Betreff: Re: Looperlative LP1 - sample rate If you're sending a square wave into a speaker, the speaker will attenpt, (not very succesfully) to push itself in and out without any in-between values. No sampler can "guess" a sine wave from a square. How would it know that you wanted a sine wave? Think of sines and squares as just different shapes.Your speaker cone will try to "draw" the shapes in the air. Gareth > Surely sound waves are always sine waves?
