DIGITAL SIGNAL PROCESSING TECHNIQUES FOR IMPROVING AUDIO CLARITY AND INTELLIGIBILITY

摘要

Methods and apparatus are described for effecting multi-band processing of an original sampled signal. The original sampled signal is separated (44) into a plurality of signal components each corresponding to one of a plurality of frequency bands wherein each band is independently processed (60, 62, 64). A dynamic range associated with each one of the plurality of signal components is independently and dynamically controlled (52). At least one signal level associated with the plurality of signal components is modified (46, 48, 50, 58). The signal components are combined (66) into a processed sampled signal.
