<p>A signal processing system for generating a parametric signal comprises an audio compressor, operable to compress a dynamic range of an audio input signal, and an equalization network, operable to equalize the audio signal. A low pass filter is operable to remove high portions of the audio signal and a high pass filter is operable to remove low portions of the audio signal. An oscillator circuit is operable to generate a carrier signal, and a modulation circuit is operable to combine the audio signal with the carrier signal to produce at least one modulated carrier signal.</p> |
