Sonification of input voltage

[jrolston]

Hi all,

I'm using Visual C# with Measurement Studio and acquiring voltage waveforms at around 40 kHz (in 250 millisecond blocks).  I'd like to play these waveforms over the computer's sound card as they're being acquired (for example, to help debug ground loops in the measurement setup).  Does any one know of any ways to pipe the acquired data to the sound card?

Thanks!

John

Hi John,

What will be the format of the data that you want to stream to your sound card.  If you were planning to use a WAV file, you could use some Microsoft ActiveX calls to open up a media player.  Otherwise, you would need to know the Windows API for your sound card to stream data to it from your program.
