Give this a go -----Original Message----- From: Jacob Kruger [mailto:jacobk@xxxxxxxxxxxxxx] Sent: 13 May 2012 12:48 To: php-windows@xxxxxxxxxxxxx Subject: 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 Jacob Kruger Blind Biker Skype: BlindZA '...fate had broken his body, but not his spirit...' ----- Original Message ----- From: "Carl Roett" <carlroett@xxxxxxxxx> To: <php-windows@xxxxxxxxxxxxx> Sent: Sunday, May 13, 2012 11:55 AM Subject: Next question about binary files/combining them, etc. > Depending on what you're building, it could be very easy or extremely > difficult.
