The pipeline/graph model also works for images and other data.&= nbsp;

A movie or a sound, etc, is a function f(t) tha= t returns data at a given time. 

Should we build= a library that does more than sound?

(and yes I know= (20+ years of audio / video) it is not as simple as it sounds=E2=80=8E and= the devil is in the details, but at the high level it is and should be sim= ple)

&nb= sp;

I disagree.= I would say the basic primitives are a sample and a frame. Samples can be = obtained and processed in different ways, including recording, reading from= file or generating algorithmically.

&nb= sp;

The process= ing is often represented as a pipeline or graph with producer, filter and c= onsumer nodes. This is a higher level framework that builds upon the basic = blocks of frames and digital signal processing algorithms.
