The simplest way to decode binary data encoded with fsk 1200bs

[couderta]

I'm looking for the simplest way to decode binary data encoded with fsk 1200bs (with a fx614).
It seems that using the sound card is a good choice.
I use windows (I know...) so Directsound seems to be the good API.
The compilor is Visual C++.
I would like to know if someone had tried before or has a simple code.

Thanks.

fsk soundcard

There are several software packages for sending and receiving ax25 packet radio signals with a soundcard at 1200buad AFSK or 9600 baud FSK.

SOftware exisits for decoding FSK pager signals with a soundcard.

Re: fsk soundcard

I know but I'm only interresting in code because I need to get the data to feed indicator (altimeter, speedmeter...)
My data are not in the AX25 format but just binary
