<div dir="ltr"><div><div><div>Hi!<br><br></div>Is there some way to fill an array (table) with an arbitrary wave form programatically? I know I can use sinesum or cosinesum to generate sums of sinusoidal wave forms, and in theory any periodic waveform can be generated this way. But I want to generate wave forms using more complicated trigonometric expressions, for example sin(sin(x) * pi) or sin(x) ^ 3. I'm not sure what they would sound like (which is what motivates me to try), or if there's some way to transform these expressions to use only sinesum or cosinesum (my knowledge of math is somewhat limited).<br>
<br></div>Any suggestions on how I could do that in Pure Data? I could create an audio file using some other software tool and then load it into Pure Data, but I'd like to know if there's some way to do it directly in PD.<br>
<br></div>Thanks.<br><br></div>
