class:: Pbinop
summary:: binary operator pattern
related:: Classes/Pnaryop, Classes/Punop, Classes/BinaryOpFunction
categories:: Streams-Patterns-Events>Patterns>Math
description::
Returns a stream that applies the binary operator to the stream values of the receiver. Usually, this is the result of applying a binary operator (i.e. a method with one argument) to a pattern.
Examples of binary operators are: +, -, /, *, min, max, hypot ...
ClassMethods::
method::new
argument::operator
operator to be applied
argument::a
a pattern (or compatible pattern input)
argument::b
a pattern (or compatible pattern input)
argument::adverb
Examples::
code::
(
var a;
a = Pbinop(\hypot, Pseries(0, 1, 12), Pseries(3, -1, 12));
a.asStream.all;
)
// this is the same as:
(
var a;
a = Pseries(0, 1, 12).hypot(Pseries(3, -1, 12));
a.asStream.all;
)
// also written as:
(
var a;
a = Pseries(0, 1, 12) hypot: Pseries(3, -1, 12);
a.asStream.all;
)
// some common cases:
Pseq([1, 2, 3]) + 2;
Pseq([1, 2, 3]) / Pseq([3, 4, 5, 6]);
max(Pwhite(-10, 10, inf), Pseq([0, 2, 3, 4]));
::
code::
// sound example
(
SynthDef(\help_sinegrain,
{ arg out=0, freq=440, sustain=0.05, amp=0.1;
var env;
env = EnvGen.kr(Env.perc(0.01, sustain, 0.2, amp), doneAction: Done.freeSelf);
Out.ar(out, SinOsc.ar(freq, 0, env))
