SoundCard/Modem

[Sahil Malik [MVP]]

A really simple question.

I have an interactive application that works using a microphone and speakers
plugged into the sound card.

I'd like this app to work over a telephone now. VOIP or a real telephone
line - both are workable options.

I am clueless how to proceed further, this was developed in speech SDK.
Please help.

I am not sure if System.Management will help in this regard - can you
elaborate?

I never worked this out on a interactive app however a while ago i was trying
to stream sound across a network and the easiest way was to use "Direct Sound"
and NetworkStream. I found very easy to work with direct sound because you
dont need to work very close to the metal.

Look at the WaveFormat structure:

Another way would be to intercept the sound from your windows "sound system".
Here is a simple example:
