The code for the above can be obtained here: Code:Song_bird:part1. As expected, most of the energy of the signal, in this case the bird's high frequency voice, is concentrated in the frequency band of around 2000 - 6000 Hz. To filter this out, we can apply a low-pass filter with a cutoff frequency of around 2000 Hz.
