Embodiment Construction

[0022] refer to figure 1 As shown, it is an audio signal measurement implementation structure diagram of a preferred embodiment of the audio verification and analysis system of the precision audio analyzer of the present invention. exist figure 1 Among them, a control host 1, a client 2 and a precision audio analyzer 3 form an audio analysis system. The control host 1 and the tested client 2 can be connected via a local area network or other available connection methods, such as the Internet (not shown in the figure). Wherein the control host 1 is connected to the precision audio analyzer 3 through a 3.5mm connection terminal 4, the control host 1 is equipped with audio test software, which controls the precision audio analyzer 3 to perform audio testing and analysis through the audio test software. Described client machine 2 comprises sound card 21, and this sound card 21 has a linear input port 210 and a linear output port 211; Described precision audio analyzer 3 has an a...

Abstract

The audio check analysis method for precise audio analyzer includes the following steps: to provide one host computer with audio test software installed and connecting terminal connected to the analyzer; to provide one client computer with audio input port and output port connected separately to the analog signal output port and input port of the analyzer; for the host computer to control the analyzer to generate analog signals of different frequencies and amplitudes fed to the client computer; for the client computer to record audio waveform file of the received analog signals and transmit the file to the host computer; and for the host computer to convert the file under virtual DOS mode into audio test file capable of being recognized in the analyzer and to control the analyzer to analyze the audio test file. The present invention performs software, rather than hardware, analysis for maintaining normal hardware analysis and data treating function.

Description

【Technical field】 [0001] The invention relates to a test technology for audio verification analysis, in particular to an audio verification analysis method for a precision audio analyzer. 【Background technique】 [0002] When the new precision audio analyzer AP2722 uses the old test files to perform AC97 or Azalia audio 44K&48K sound effect verification, the sampling analysis time is too long, and there is an error in the analog signal to digital signal (Analog to Digital, A-D) recording test However, the accuracy of the test results cannot be guaranteed, that is, the test results from analog audio signal input to digital recording cannot be analyzed. The digital signal processor (Digital Signal Processing, DSP) version number (Rev) 07 of the new precision audio analyzer AP2722. Only the old precision audio analyzer AP2722 (DSP Rev: 06) and devices below AP2722 (eg: AP2322) support this A-D function, which can guarantee the correctness of the test results. The AC97 is an au...
