In this paper we developed lossless audio compression by using reversible transforms that map their coefficients as integers to integers. Three reversible transforms, S-transform, TS-transform, and SPtransform were implemented to decorrelate redundant signals in music samples. Golomb-Rice code combined with the Laplacian probability density function (PDF) was used to encode the decorrelated signal. Various audio samples excerpted from the SQAM-CD were tested by prototypical lossless compression system we developed and compression results are presented with comparing with the result obtained by using linear prediction method in our previous work. . . .
