I want to demodulate and decode FSK Modulated Audio Data in C Language.
Data is modulated using similar algorithm as of Caller Id.

Can anyone suggest me any good and efficient algorithm for this.

I tried zero crossing algorithm but it was not efficient as no. of samples per bit were less to get an accurate result

Sampling Rate is 8Khz
Carrier Frequency is 1600Hz
Frequency Difference is 400Hz from Carrier

Any help would be deeply appreciated.

Thanks in Advance

Deepak Madan
