A signal processing system (10) for generating a parametric signal comprises an audio compressor (14a, 14b), operable to compress a dynamic range of an audio input signal, and an equalization network (16a, 16b), operable to equalize the audio signal. A low pass filter (18a, 18b) is operable to remove high portions of the audio signal and a high pass filter (20a, 20b) is operable to remove low portions of the audio signal. An oscillator circuit (22 a, 22b) is operable to generate a carrier signal, and a modulation circuit (23) is operable to combine the audio signal with the carrier signal to produce at least one modulated carrier signal. |
