Audio data in the IEEE float format is used by the professional quality audioeditors as the format of choice during the editing process and also for storingthe intermediate results. The proposed algorithm transforms the floating-pointvalues into integer values, in a completely portable way across architectures andcompilers. The transform maintains all the important properties of the originalvalues, such as magnitude relations, linear temporal relations and, most importantly,compressibility. It produces a sequence of integers and an additionalbinary stream used for lossless reconstruction of the original values. Furthermore,the proposed algorithm can be successfully applied to other areas suchas medical, science and space data compression. Our algorithm obtains on average7% better compression than the existing multimedia-aware compressionalgorithms, while being also faster.
