Emulating a modem: Converting Data to sound & vice versa

[Arokh]

Hi

 

I want to convert data to sound and vice versa,

so basically something that a modem does.

 

For testing purposes I want to connect 2 applications and transfer data from one to another.

Of course speed matters but resilience against noise and alike is a much greater concern.

The sound quality will be like conversation though cell phones.

 

Since I still haven't found something that does such a conversion,

anything that does it will be of help.
