  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.
