System and method embodiments are provided for very short pitch detection and coding for speech or audio signals. The bearing set includes a tube and a pair of bearings firmly secured in opposite ends of the tube. The tunneling device includes an interchangeable handle connectable to each of the ends. Embodiments also include the storage, querying and retrieval of information corresponding to type information for constructed types within an application framework. The processor receives the signals and performs a calculation of the signal. From the evaluation of variables, such as operating time, phase andor amplitude, the individual microphone locations are virtually weighted, and the audio signals from the microphones are added or otherwise combined.
