METHOD OF LEVELING A PLURALITY OF AUDIO SIGNALS

摘要

A system with an input amplifier to receive and amplify a first audio signal, an output amplifier to output an audio signal which includes at least one of the amplified first audio signal and a second audio signal, a controller to adjust the input amplifier to a first input amp gain and the output amplifier to a first output amp gain to provide an output signal including the first audio signal at a first output signal level. The controller is to adjust the output amplifier to a second output amp gain to provide an audio output including the second audio signal at a second output signal level and determine an output amp ratio by dividing the first output amp gain with the second output amp gain. The controller is to determine a target input amp gain by multiplying the first input amp gain by the output amp ratio and adjust the first input amp gain to the target input amp gain to provide an audio output including the first audio signal at a third output signal level.
