audio_analysis.h File Reference

Audio Analysis for flagging if the audio passed in meets the characteristics that may mean a bird call is present. The general algorithm is to perform a Fast Fourier Transform on the array of samples passed in. Then the magnitude squared is taken to find the power spectral density. This is then compared against [something] to determine if the audio is "interesting". More...
