The latest Krestianstvo is based on the OpenQwaq (Squeak 4.1 derived)
image, and does not introduce any new low-level audio library yet. But, as
it is OpenQwaq/Croquet based, it has OpenAL support by default, where you
could find a lot of low-level stuff that work with audio. So, you could try
any of Croquet family images for OpenAL coding.
Another audio library to try is a QuickTime library from OpenSophie project
(existed Squeak repository http://www.squeaksource.com/SophieGoldDig.html).
The official project site seems to be down, where the developer image was
available for a long time.

Regards,
Nikolay


And where is the WAV spec for 24bit integer and 32bit float samples?
