Re: Next question about binary files/combining them, etc.

Thanks.

Will check out those things, and, yes, know of stack overflow, but not 
always easiest to find completely useful info on that site...:)

Aside from that, this is more to do with adding things like spoken sound 
effects to pages, etc. using small sound clips of TTS output using the 
various voices/synthesizers I have here - have like 20 different voices 
might want to try use, and the idea is to literally sort of mix short 
sentences/phrases together, etc., but aside from hardcoding all the 
different, complete sound clips, the idea would be to sort of mix a somewhat 
limited dictionary/collection together into various combinations, but, they 
wouldn't be huge files in terms of file size/bandwidth, etc., and would most 
likely either load them into soundManager using JQuery, or load them sort of 
dynamically as  BGSound sources for something like a somewhat hidden inline 
frame, etc.

Thanks again

STay well
