I want to grab TV Tuner Raw Samples for implementing FM receiver.
I need to have mechanism to Tune desired frequency and then grab Samples of that frequency, in this case it would be IF samples and then implement FM receiver over it.
I have already seen various examples at codeproject but they are not working on raw samples instead getting decoded data for video and audio.
Can any one tell me how to do this under windows. Programming language could be c, c++, C# or VB?

For analog decoding, you need to apply Kalman filters to extract the actual data from the signal/noise. Usually, this is done with C or C++ code. Java would work as well; however, since this is highly performance sensitive, VB would not be recommended, and C# would be equivalent (IMO) to …

Let me get this straight. You want to demodulate IF signals digitally from a Windows PC? Isn't this sort of insane? IF signals are usually around 20 to 100 MHz in frequency, depending on application, meaning that your analog-digital converter would have to run at about an order of magnitude …
