Abstract :
Use of short floating-point formats that are shorter than the IEEE floating-point standard (ANSI/IEEE S+A 754-1985), 24+8-b, in digital audio applications is studied. The performance of these formats is analyzed in different parts of the digital audio signal processing chain and compared to the performance of widely used fixed-point formats. The statistics of practical audio signals and the characteristics of modern floating-point signal processors are considered in the analysis
