摘要：A method of performing gain adjustment in an electronic device includesdetermining a first set of spectral frequency values and determining a second set ofspectral frequency values. The first set of spectral frequency values corresponds to a

high-band portion of an audio signal received at the electronic device. The second set ofspectral frequency values approximates the first set of spectral frequency values in thehigh band portion of the audio signal. The method includes estimating a spectraldistortion corresponding to a difference between the first set of spectral frequencyvalues and the second set of spectral frequency values and adjusting, based on thespectral distortion, a gain value corresponding to at least a portion of the audio signal.The method also includes transmitting an encoded bitstream that includes informationcorresponding to the adjusted gain value and the second set of spectral frequencyvalues.
