Claim:
An audio smoothing system for smoothing an audio waveform to generate a smoothed waveform, comprising: an audio generator for generating the audio waveform; audio smoothing device electrically coupled to the audio generator for receiving the audio waveform and dividing the audio waveform according to a predetermine cycle time to form a plurality of adjacent waveform intervals, and each of the waveform intervals having a corresponding average waveform amplitude, wherein the waveform interval is further divided into a plurality of wavebands including a front waveband, a middle waveband, and a rear waveband, and the wavebands have a front waveband parameter, a middle waveband parameter, and a rear waveband parameter respectively; and an operating interface electrically coupled to the audio smoothing device for generating and transmitting an input sound volume to the audio smoothing device; wherein the audio smoothing device divides the input sound volume by the average waveform amplitudes respectively to obtain a plurality of waveform parameters, and further sets the front waveband parameter of the waveform interval equal to an average of the waveform parameter of an adjacent waveform interval preceding to the waveform interval and the waveform parameter of the waveform interval, and sets the middle waveband parameter of the waveform interval equal to the waveform parameter of the waveform interval, and sets the rear waveband parameter of the waveform interval equal to an average of the waveform parameter of an adjacent waveform interval succeeding to the waveform interval and the waveform parameter of the waveform interval, and then the audio smoothing device multiplies the waveform parameters with the waveband amplitude values respectively to obtain the smoothed waveform.
