Frequency generator program

[Shadow]

Hey all,

 

I was thinking about making a program that would generate a steady sound at a inputted frequency. It would play the frequency at a random time between 0 and x seconds, probably something like ten, from pressing "Start". If you'd hear the frequency, you'd press a button. It's purpose would be to test if you can hear that given frequency. Now, I think I'll manage everything, except the GUI, which I can live without of, and the sound generator. Anybody have any tips? I'm gonna use C++.

 

Cheers,

 

Gabe

Okay, let me rephrase the question; how do you play a sound at a given frequency, for a given duration, but NOT through PC speakers, in C++? I searched the web, couldn't find a thing, so I found myself a tutorial for OpenAl...but I don't even know if OpenAl is capable of that. So, any tips?

Research if you have questions ask.............

note: search parameters should revolve around tone generator not frequency for your purposes

k so the first two in that search are probably all you need to get started I can't find anything aside from these either...........

Perhaps ChucK is a better language to do this with than C++:

Where do you plan to output the signal?

@Buttacup: I was trying to do it without using msdn, I'm not that familiar with the Windows API yet, which was why I was hoping someone would know of a separate library I could download (eg. a Beep() function that would use external speakers instead of the PC speakers). But this will be good enough, I confess I don't recall coming over it in my searches, but then again I did search for frequency and sound, but never for tone...so that may be it. Thanks

 

@bascule: I'll have a look, thanks for the tip

 

@Pantaz: External speakers.
