Hi All,
I have some difficult files that I need to process. These are files recorded from a transmitter and include heart beats of a wild bird. I am trying to count these beats and calculate the time between beats etc. We are particularly interested in targeting and describing areas in which the rate changes (i.e. flight, foraging, misc. movements).
There was actually a very helpful post that I found on this forum that does exactly what I need: Monitoring time difference between two points on waveform
HOWEVER, I need to better clean the data. There is too much background noise and the heart rate is not always the loudest sound in in a given second etc. Is there way to better fine tune a file so that it will amplify a certain frequency to be the loudest? or a certain band of frequencies? I have dabbled a little and it appears that amplifying and cleaning only does so much and that other peaks or quieter heart beats causes the above program to miss or over count beats.
This has a lot to do with inconsistent sound recording from the transceiver as the animal moves further or closer away from the antenna etc.
I’ve attached a partial file to this post. Would love to some more brain power on this.
