Abstract
A Wide-band Equalization System ('WBES') based on near- and far-field measurement data. The WBES includes a subwoofer equalizer having an FIR filter together with decimator and interpolator filters for processing low frequency signals. The WBES may also include satellite channels for processing mid- and high-frequency signals, where each satellite channel includes cascaded IIR filters that process mid-frequency and high-frequency signals, respectively. The WBES may also include a DSP that performs the functions required by the IIR and FIR filters.
