<p>The present invention relates to a delay generation apparatus for verifying MOS measuring equipment, which delays an audio signal outputted from MOS measuring equipment, then inputs the delayed audio signal into the MOS measuring equipment, and verifies whether the MOS measuring equipment measures the delay accurately. According to the present invention, the delay generation apparatus for verifying MOS measuring equipment comprises an A/D converter, a D/A converter, and a control unit. The A/D converter operates by being connected between MOS measuring equipment and a control computer, and converts an analog audio signal of an original WAV file, which is played by the MOS measuring equipment, into digital audio data. The D/A converter converts digital audio data of a collection WAV file, which is to be collected by the MOS measuring equipment, into an analog audio signal and outputs the analog audio signal to the MOS measuring equipment. The control unit stores digital audio data converted at the A/D converter in a reception-side data buffer; reads the digital audio data stored in the reception-side data buffer and stores the digital audio data in a transmission-side data buffer; and outputs the digital audio data stored in the transmission-side data buffer to the D/A converter after a preset delay time received from the control computer has passed.</p> |
