MFCC with Java Linear and Logarithmic Filters

I am implementing MFCC algorithm with Java. There is a sample code for triangular filters and MFCC at Java. Here is the link: MFCC Java However I should follow that code written in Matlab: MFCC Matlab

My question is that at Matlab code it talks about linear and logarithmic filters however there is nothing about that at Java code. I should measure the performance of 开发者_开发知识库logarithmic and linear filters but I implemented that Java code and there is nothing about that. Also I didn't understand what these fbins and cbins at Java code?


The Java code does include a non linear transformation, basically mapping your linear frequency scale to the mel-scale. 'cbins' refer to the center (frequency) of each filter bank.

The Java code is exactly what an MFCC code should look like. So, it should work well for you.
