features extraction problem

[loop4633]

Hi guys, I'm trying to understand how autobi works. I load this library in eclipse because and I would like to extract some features for use these in my experimental project. My problem is that I do not understand how I can use this library, in other words I had read wave file but how I can get energy or pitch feature? I try to extract energy (I think this correspond with power of spectrum) but Spectrum constructor required "double[][] data, double starting_time, double frame_size, double freq_resolution" how I can get this parameters? There is any tutorial that's illustrate me how I can get features from wav file step by step by library in eclipse?

I hope anyone can help me. Compliments for your work, bye.

I'm sorry, power spectrum is different to energy. How I can calculate energy?

Thanks again
