    摘要： An acoustic control device for generating a pseudo echo signal by filtering an input remote speaker signal by using a plurality of adaptive filters and controlling the adaptive filters to perform filtering based on filter coefficients generates an error signal by subtracting a pseudo echo signal from an input nearby speaker signal, determines a convergence state of the filter coefficient based on the error signal, and controls the width of data input to the adaptive filter when the filter coefficient is determined to be converged

    摘要： Provided is a transmission apparatus for matching sound quality measurement sections of a variable bandwidth multi-codec. The apparatus includes a measurement section setting unit setting a measurement section, which is to be measured for sound quality, in units of time; a first conversion unit converting the measurement section into a measurement section in units of samples; and an information synthesis unit synthesizing information regarding the measurement section in units of samples with a digital original sound and outputting the synthesis result. In addition, provided is a method of matching a measurement section of a reference sound, based on which the end-to-end sound quality measurement of the variable bandwidth multi-codec is performed, and a measurement section of a sound produced by the variable bandwidth multi-codec in a real-time Internet multimedia service. Therefore, distortion of measurement results due to un-matching measurement sections can be reduced.
