# design overview

Processing algorithms are designed as much as possible to be data type and domain independent. This allows a common set of functions and objects to be used for a variety of modalities, such as sound or graphics, and in arbitrary domains, such as time, space, or frequency. Algorithms are type generic which means they can process any type of data that has the appropriate mathematical operators defined (typically +, -, *, and /).

Whenever appropriate, objects use compile-time strategies for handling different behaviors, such as interpolation.

## domains

Sampling domains are abstracted through an observer design pattern. The subject, a Domain object, holds a sampling rate/interval amount and notifies its observers, DomainObserver objects, whenever it changes value.

## genericity

Gamma objects are templated on their value type allowing them to be used with any arithmetic data types, such as, scalars, vectors, and complex numbers.

RMul<float > rMul(0.99); // decaying envelope RMul<Vec3<> > rMul(Vec3<>(0.9,0.8,0.7)); // 3 decaying envelopes RMul<Complex<> > rMul(Polar<>(1.00, M_2PI/8)); // complex sinusoid RMul<Complex<> > rMul(Polar<>(0.99, M_2PI/8)); // complex exponential

## syntax

Processing objects are typically either a generator or a filter and can be either domain observers or not. Objects adopt a standard processing operator interface similar to functional syntax. Generators return their next value with the () operator and filters return their next value with the (T) operator, where T is a value type.

gen::RAddrAdd(1, 0); // recursively add 1 starting at 0 for(int i=0; i<4; ++i) // prints "1 2 3 4" cout << rAdd(); fil::Delay1 delay1(0); // 1 element delay starting with 0 for(int i=1; i<5; ++i) // prints "0 1 2 3" cout << delay1(i);
