All Implemented Interfaces:

NoiseProducer

Adds noise to a Sample from one of the given noiseFiles. By default this noise comes from one of three files, all located in /sounds/noises/: radio_tuning.wav, restaurant.wav, and swimming.wav. This can be overridden by passing the location of your own sound files to the constructor, e.g.:

 String myFiles = { "/mysounds/noise1.wav", "/mysounds/noise2.wav" };
 NoiseProducer myNp = new RandomNoiseProducer(myFiles);
