Hardware independent audio for Amiga

AHI User's Guide, version 4.16

Martin 'Leviticus' Blom


Paula is one of the custom chips, and she is responsible for the sound (and more). Unfortunately, this chip has not been updated since the very first Amiga was released.


The name AHI was chosen because the functions in the system had to have a prefix, and the author couldn't come up with anything better than Audio Hardware Interface, something that he has regretted ever since. The suggested pronunciation is "atchii", as in "God bless!".


Originally designed in 1986 by Karsten Obarski, modules have become a de facto standard for game and demo music. The original format has been improved many times, and many new music formats have--more or less--been derived from it, including the popular S3M and XM formats.

The more channels you select, the more sounds can you play at the same time. However, due to the nature of sound mixing, the volume will decrease as well. If you try to play more sounds at the same time than there are channels, the least important sounds will be muted until the other sounds have finished playing.
