generate sound through Labwindows

[mhs100]

Hi all,

There is a VI in Labview which generates sound from the built-in sound card in cpu. Its name is                      "Generate Sound. VI" . It plays the sound of  sine wave, triagular wave , square wave etc at different volumes. Is there any project in Lab Windows which does the same?

Any help will be greatly appreciated.

Hi,

If you use the sample finder, Help / Find Examples, and search for sound it will yield two sample projects...

Another option is looking at the functions StartPCSound ( frequency) and StopPCSound () in the Programmer's Toolbox.

Hi

If I use the StartPCSound ( frequency) and StopPCSound () , then please tell how can i change the Volume of sound by using these functions.

Hello,

As Wolfgang mentioned, there are several samples.

II had once to make a superposition of a few frequencies. After some searching and puzzling, this went very well with "direct sound". Via CVI --> Help --> Windows SDk --> DirectSound, I found a tutorial. From this, I made the attached example.

Succes, Jos
