SYSTEM AND METHOD FOR STEREO FIELD ENHANCEMENT IN TWO-CHANNEL AUDIO SYSTEMS

摘要

The present invention provides methods and systems for digitally processing audio signals in two-channel audio systems and/or applications. In particular, the present invention includes a first filter structured to split a two-channel audio input signal into a low frequency signal and a higher frequency signal. A M/S splitter is then structured to split the higher frequency signal into a middle and a side signal. A detection module is then configured to create a detection signal from the middle signal, which is used in a compression module configured to modulate the side signal to create a gain-modulated side signal. A processing module is then structured to combine the low frequency signal, middle signal, and the gain-modulated side signal to form a final output signal.

1. A method for stereo field enhancement in two-channel audio systems, comprising:
splitting a two-channel audio input signal into a low frequency signal and a higher frequency signal using a first cutoff frequency, splitting the higher frequency signal into a middle signal and a side signal, processing the middle signal using a detection module to create a detection signal, adjusting the gain on the side signal using a compression module modulated by the detection signal in order to create a gain-modulated side signal, and adjusting the gain-modulated side signal with a makeup gain.
