Nelson- The good news here is that a flute produces the closest thing to a pure sine wave that you can get from a musical instrument. You'd probably have to open the audio in port and start counting zero-crossings and reject anything too far out of band.
Even looking at just an A-440Hz signal, though, that means looking looking for a transition every 1.8 milliseconds. System ticks aren't that accurate. If you're not using a machine with an accessible DSP chip hooked up to your audio input I think you're going to be dealing with some very low-level code - deeper than you'll be able to get with Transcript. -- -Mark Wieder [EMAIL PROTECTED] _______________________________________________ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution
