I can't make an estimate, but I'd consider a couple of things:

(1) enqueue sound requests for a separate process to deal with rather than 
making your process wait for the sound to be produced

(2) you could make wrappers for CompiledMethods by copying them and editing 
the bytecodes so that they could (for instance) make sounds. This way you 
wouldn't have to change the source every time you turned a sound on or off.

Terry Raymond's Crafted Smalltalk Debugger for VisualWorks does this (he 
calls these edited methods "method probes"). I'm sure that there's sample 
code (at least for VW) out there.
