| I'm creating a CHIP-8 emulator (I'm hoping this will make an NES emulator easier in the future) and sound-wise, I simply need to emit a single pitch tone when the sound timer is greater than zero. I don't want to deal with DirectX for something this simple, especially since I'm using GDI+ for graphics, so I wouldn't be using any other components of DirectX. The problem is, I can't find a way to emit a simple tone out the speaker. I know about Console.Beep, but for one thing, it comes out the motherboard speaker which isn't what I want and second it pauses the program while it plays the sound which may mess with the framerates a bit. Is there a way to emit a tone using only the .NET Framework or will I need to use some sort of other library? |

| I used System.Media.SystemSounds.Beep.Play, which is probably just a wrapper for the Win32 PlaySound function. |

| That's not quite what I'm looking for. That plays that Windows beep sound with an empty space between. I need a constant stream of sound for as long as the timer is going. Basically, I want a Console.Beep type thing only coming out of the speakers instead. Thanks though! |

| If you're willing to Pinvoke your way through it, waveOutWrite might be adequate although i've never used it. |

| I found quite a few examples of doing this in C# on the web. Just use "C# tone generator" as your search terms. |

| I used MIDI for my CHIP-8 emulator - this is probably the easiest way for simple tones (there's a basic MIDI API wrapper in the source). For my Master System emulator, I'm using the Windows waveOut API, using the wrapper by Ianier Munoz. .................................................................................................................................................................
