iOS beep() sound on iphone?

[alexandergre]

in c#- c++, vis basic there is a method called console.beep(int1, int2);
int1: frequency int2: duration.

however is there such a thing in xCode?
if no can you please tell me a program which can generate sounds with a specified frequency/duration?

Thank you very much.

Look into AudioServicesPlayAlertSound.

PlayAlertSound doesn't allow you to programatically and independantly set the frequency and duration.

You could write a small audio synthesizer method and feed the resulting audio sample vector to Audio Queues or to the Audio Unit RemoteIO.

Go with AudioQueues if any, RemoteIO is a powerful beast but its terribly documented and very cryptic to begin with. Use it only if you HAVE to
