public class Crop
extends Raw

Designed to be a general "cropper". It does no real preprocessing, other than just cutting tails or heads or the middle of the sample array for the fixed-length chunk. While can be used as a regular preprocessing module (in which case it is equivalent to Raw, except cropped), Crop meant to be used in conjunction with other modules either through Preprocessing pipeline concatenation or the implementation of the cropAudio() API. If no parameters specified, by default cuts out the first 512 elements of the sample array.
