Method and system for real-time processing of the recorded PCM data to get the desired full-scale range of values

摘要

A method and apparatus for processing pulse code modulation (PCM) data that do not reach the full dynamic range of a transmission bus. The method and apparatus provide an output processed PCM data having the maximum peak signal allowable by a transmission bus. The output signal limitation is also dependent on a sampling or recording frequency of input signals. In view of the sampling or recording frequency, the invention scales the processing of the PCM data accordingly.
