C#.NET2, pustanje jednostavnih zvukova

^{04.02.2007. u 00:20 - pre 209 meseci}

Dosada sam koristio samo, u C#-u, preslusavanje odredjenih audio fajlova, i to preko pinvoke na winmm.dll, pa playsound.

Medjutim, treba mi sljedece, jako jednostavno : da mogu "odsvirat" odredjenu frekvenciju, u odredjenom trajanju. Recimo funkcija sviraj(2250, 10); , koja bi odsvirala jednolican zvuk frekvencije 2.25kHz, u trajanju od 10 milisekundi. Ima li tko kakvu ideju oko ovoga?

_{Q: HSP56 Micromodem nece da radi kompjuter ga prepozna a kad treba da se konektujem nece ne daje ni znaka zivota. u cemu je problem.

A: Crko mozda od grmljavine mozda od spanaca. Uglavnom baci ga u WC solju jako povuci vodu. Skupi 5e i uzmi drugi i ne postuj temu na pogresno mesto.}

Code:
using System.Runtime.InteropServices;

public class whatever {
[DllImport("Kernel32.dll")]
public static extern bool Beep(UInt32 frequency, UInt32 duration);

public static void beepTime() {
Beep(1000, 300);
System.Threading.Thread.Sleep(300);
Beep(2000, 400);
System.Threading.Thread.Sleep(300);
Beep(500, 200);
System.Threading.Thread.Sleep(300);
}
}

Valjda se da je ovo ono što si hteo.
