Abstract
A multiband compressor suitable for compressing the dynamic range of an audio signal in a broadcasting system is disclosed. The frequency band with the highest predictable energy is selected as a master band with the energy level in this band used to control the gain in the other (slave) bands. When the energy in a slave band exceeds a predetermined level, additional control of the signal level in that band occurs. The described compressor has the advantages of both the wideband compressors and multiband compressors without the disadvantages of these compressors. In addition to the compressor, a unique overshoot protection circuit is described.
