So it is time for an updated sound.datatype, isnt it?

Hans, thank you for your answer, I will take a look at this library but it may make a "generic engine" support only 1 audio file format ... that's not top :(.

Do you know if theres any chance to get the source code of this work to improve it in a way that it will become standard in the near future? Datatype is a (still) nice system for the handling of all computer art related data, and it should support modern hardware for sound, too...

I dont know if my knowledge of AHI is deep enough to make up some SDK-quality documentation and examples.

There are libraries for loading other formats on os4depot too. There are, for example, mp3 and ogg-vorbis decoder libraries.

You can use the 8-bit sound data loaded using datatypes with OpenAL. It's just sad that you won't be able to load full-quality 16-bit+ audio with datatypes.
