I'm looking for some C or C++ code that will allow me to access the Amiga's
sound capabilities to play a musical note or a frequency. The function I
have in mind might be used something like:
frequency_play(440.0); /* play a 440 Hz signal */
or
Note A = note_create("A"); /* create a note */
note_play(A); /* play it */
Any leads on something along these lines would be greatly appreciated.

It has lots of nice features to get you up and running very quickly. It has a bit of overhead, so may not be the best for really fast applications, but for simple ones it really takes the pain out of programming sound on this machine. You can queue up notes, frequencies, samples & light them off. You can Wait() at a message port for a particular note to start playing & more... ==================================================================== Kent Polk - Southwest Research Institute - kent@swrinde.nde.swri.edu Motto : "Anything worth doing is worth overdoing" ====================================================================

In the original NewZAP source distribution (so long ago - check your Fish llibrary, disk # 52 or so) there's a routine called 'beep.c'. It's probably as minimal a sound routine as can be done for the audio device. If you need to play note-names, you'll need to supply a note-name to frequency table; refer to the new RKM. +----------------------------------------------------------------------------+ | Dallas J.
