A dedicated codec for compression of Gravitational Waves Sound

A dedicated codec for compression of gravitational waves sound with high quality recovery is proposed. The performance is tested on the available set of gravitational sound signals that has been theoretically generated at the Massachusetts Institute of Technology (MIT). The approach is based on a model for data reduction rendering high quality approximation of the signals. The reduction of dimensionality is achieved by selecting elementary components from a redundant set called a dictionary. Comparisons with the compression standard MP3 demonstrate the merit of the dedicated technique for compressing this type of sound.Comment: All the results in this paper can be reproduced using the MATLAB software which has been made available on http://www.nonlinear-approx.info/examples/node010.htm
