Abstract:
1. An audio processing system, comprising: a selector to maintain a voltage level of a first audio signal among at least two audio signals at a value, to select a second audio signal in response to a selection, to gradually increase the voltage level of the first audio signal to a voltage level of the selected second audio signal among the at least two audio signals for a time, and to output the selected second audio signal; an amplifier to maintain the voltage level of the selected second audio signal received from the selector at a value, and to amplify the selected second audio signal by a ratio and a noise prevention module comprising a plurality of capacitors disposed at the input side of the selector, the capacitors configured to respectively receive the at least two audio signals at one end and being connected to the respective input lines of the selector at another end.
