//Blackman Window

var sig, size, alpha, a0, a1, a2;

size = 2048;

alpha = 0.16;

sig = Signal.newClear(size);

a0 = 0.5*(1-alpha);

a1 = 0.5;

a2 = alpha*0.5;

sig.waveFill( { arg x, i; a0 - (a1*cos( (2*pi*x)/(size-1) ) ) + (a2*cos( (4*pi*x)/(size-1) ) )}, 0, size );

// your OSC message

z = [0, [\b_alloc, 0, 2048, 1, [\b_setn, 0, 0, 2048] ++ sig]]

)

// z is the message to put into your score

score.add(z); // etc ...

OR - you can save your signal out to a soundfile, then just read it in with \b_allocRead.

Hope that helps.

How would I add something like this into a Score?

Try with
~blackman = Buffer.loadCollection(s, sig, 1);

~blackman.plot;

I'm wondering if there is an easy way and/or how one would fill a Buffer with something like the following for NRT use.

(
//Blackman Window
var sig, size, alpha, a0, a1, a2;
size = 2048;
alpha = 0.16;
sig = Signal.newClear(size);

a0 = 0.5*(1-alpha);
a1 = 0.5;
a2 = alpha*0.5;

sig.waveFill( { arg x, i; a0 - (a1*cos( (2*pi*x)/(size-1) ) ) + (a2*cos( (4*pi*x)/(size-1) ) )}, 0, size );
~blackman = Buffer.sendCollection(s, sig, 1);
)

I'm not sure how this is done with the \b_alloc messages and such.

Thanks very much,
sw
