| 摘要 |
A signal processing system for use in a multi-channel audio system having a plurality of power amplifier channels connected to a plurality of loudspeakers and power amplifiers, configured to receive and reproduce audio signals through the loudspeakers, and at least a first channel of the plurality of power amplifier channels amplifying a first audio signal, comprises a processor responsive to a signal level threshold applicable to at least said first channel, such that at and above the signal level threshold, the first audio signal in the first channel is amplitude limited and a portion of at least the first audio signal is mixed into at least a second channel. The amplitude limiting and signal mixing is configured so as to reduce introduction of at least one of: a) audible tonal distortion; and b) perceivable spatial distortion; of a sonic presentation due to said limiting and signal mixing.
