A dedicated method for irreversible compression of Gravitational Waves Sound with high quality recovery is proposed. The performance is tested on the sound signal which has been produced with the first gravitational wave that was detected, and on 36 theoretically generated signals. 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 dictionary. Comparisons with the compression standard MP3 demonstrate the merit of the dedicated technique for compressing this type of sound.
