Fabou	Posted - 12/09/2008 : 09:27:56 AM Hello, I am a researcher in biology working on a pest that burrow inside corm of plants. I have a sound recording of the signal corresponding to the pest vs a lot of noise : Here is the Frequency/Amplitude graph of the different pest signals (color line) vs the noise (black line). We can see a peak for the pest signal between 60 Hz and 600 Hz that cannot be seen for the noise. I want to analyse a lot of different sound records in order to detect the pest automatically in these records. I have heard about an adaptive (or adapted?) filter which takes for input the Frequency/Amplitude of the pest signal and compare it (using FFT transformations) to the whole recording, and when there is a pest signal in the recording, the probability given by the filter reach a higher threshold. Do you have an idea of how to do that with OriginPro 8 ? Thanks in advance for your answers. Best regards,
