COMPRESSOR BASED DYNAMIC BASS ENHANCEMENT WITH EQ

摘要

A system and method for improving the low frequency response of a loudspeaker for a relatively low input level audio signal and protecting the loudspeaker for a relatively high input level audio signal is disclosed. The system comprises: a crossover network configured to separate audio input signals into at least two frequency bands including a low frequency band; And providing an amplification gain in the low frequency portion of the input signal when the energy level of the low frequency portion of the input signal is relatively low, in response to the energy level of the low frequency portion of the input audio signal in the low frequency band, thereby improving the low frequency response of the loudspeaker, And a signal compressor configured to provide attenuation of the low frequency portion of the input signal when the energy level of the low frequency portion of the input signal is relatively high to protect the loudspeaker from being overdriven.
