Then set up a "counter" variable to cycle things through the correct number of loops, and one for the number of bps desired (not nec . a whole number). One you've set the number of bps you want t hear, that deterimnes a timed loop, in which the period is the inverse of the bps. Whatever the period of the beat rate (and that could even be input as +/- ¢ with an anchor frequency), the time consumed by the 0.033 second sine wave .wav would remain constant. For 2.5 pbs, it would be 8.25% of the 0.4 sec period. That's how I would do it. I have no idea whether the database app's connection to the OS would have its own inefficiency. 'Puter telephone dialing involves a delay of 4 sec between execution and the internal modem dialing out. It's not just my database, it's the Palm Desktop's phone dialer behaving that way too. Whether or not I could do it might or might not be useful to you. I'm sure you don't have the Mac OS, and even if if polished up the beat-rate generator real swell, it would still be just a database file required the app to run it. The cross-platform version of this database does exist, but the value of such a eat-rate generator would probably be far less than the price to you of the database to run it. (Although for $50, I could register a run-time file distributed only by the database's web site.) I agree it would be a fun project. Say, you wouldn't need this this to be learning arual tuning by any chance? <g> Mr. Bill Ballard RPT NH Chapter, P.T.G.
