Overview

This document was written in order to make it easier for developers to understand and use AHI in their own productions, and write Software That Works(TM).

ahi.device has two different API's; one library-like function interface (low-level), and one "normal" device interface (high-level). Each of them serves different purposes. The low-level interface is targeting music players, games and real-time applications. The high-level interface is targeting applications that just want to have a sample played, play audio streams or record samples as easily as possible.

As with everything else, it is important that you chose the right tool for the job--you'll only get frustrated otherwise.

Not everything about AHI is documented here; for more information, see AHI User's Guide and the autodocs.
