I have schematics for a Heathkit and an Eico function generator. Um.... they're both tube units. PM me if you are interested and I'll scan and post em this evening or tomorrow.
 
Thank you very much for answering. I was thinking for something simple, not a big project. Just a small audio generator for simple tests.

Cheers

There exist some circuits around Exar XR2206 and Maxim MAX038.

And there are some free software somewhere, and how about burning some waves on a CD and use a CD player

Not much help but maybe something to google, sure someone has better info
