Need help on this.

Can you please provide us which algorithm you have implemented for this..and can you please provide any basic explanation on this fetal heartrate detection.
Thanks in advance.

basically i was listening to the output from an fetal doppler device via a normal table conference mic setup the hardware implementation is a long story so i will directly move to the software part.

i have used the AudioRecord class from the media library to directly manipulate the input from the mic, the manipulation will give you a byte array(PCM), and you can define your sampling rate according to your need, next came the noise cancellation, android has its own classNoiseSuppressor for background noise removal but it is not that effective, so you can set up your own noise cancellation module. i have also used gaussian filter to do the same. once you get a clear signal(Raw input) you can proceed with the further heart rate calculation, that might depend on your scenario and how do you want to implement it!!
