Audio and frequencies

[Jim McCabe]

I'm interested in outputting a very specific frequency out the headphone
jack of the SPARCstation 1.  I've never used the Sparc sound chip, and I
don't know much about sound theory at all.

I'm interested in generating sustained frequencies without any noticable
break in the sound.  What would be the highest and lowest possible
frequencies that I could accurately generate on the Sparc?

And the big question -- how would I go about it?
