I have the following problem, and I was just wondering if someone could provide me with some advice. I will tell you my basic setup first. I have an external 56k voice/fax/data acer modem which connects to the serial port, and has mic and output sockets on the modem. I am on win xp pro,
using visual studio for my IDE with c/c++ for the COM programming required when using TAPI 3.1.
Currently, I am able to play wave files through the modem from my pc by selecting the appropriate terminal and outgoing media stream. I have also done the necessary conversion on the wave files so there is no conversion codec required. However, the quality of the sound is ok but I think it should be much better than it is at the moment.
Instead of playing files programmatically through the pc to the modem, I decided to play the files through my pc speakers, and took the output from the pc speakers and fed it into the mic connection on the modem. Using this method, the sound quality is superb, and there is no distortion at all. But I really need to know if this is an acceptable method to achieve the results I require. I personally think that I should play the files programmatically through the pc.
Any opinions or suggestions on this would be really helpful.
