Abstract
Compression algorithms have a constant tradeoff between higher compression ratios at the cost of better quality. The number of bits assigned in the standard MPEG encoders is controlled by the signal to masking thresholds and the scalefactor calculations performed in the psychoacoustic model of the algorithm. The developed algorithm assigns lower bits to audio samples without significant degradation in quality.
