Patent ID: 8655467

Claim:
An audio testing system adapted to test performance of an audio player for playing an audio file, the audio testing system comprising: an acquisition unit adapted to obtain an audio signal played back by the audio player when the audio player is playing back the audio file; an input unit adapted to generate a first input signal and a second input signal; a first analysis unit adapted to analyze the obtained audio signal with a first analysis method in response to the first input signal to obtain performance parameters of the audio player; a second analysis unit adapted to analyze the obtained audio signal with a second analysis method, the second analysis method: comprising dividing the obtained audio signal into a number of data blocks with space between adjacent data blocks; and analyzing parts of the data blocks to obtain another set of performance parameters of the audio player; and an output unit adapted to deliver the performance parameters of the audio player acquired by the first analysis unit and the second analysis unit; wherein analyzing result of the first analysis unit is more accurate than that of the second analysis unit, and analyzing efficiency of the second analysis unit exceeds that of the first analysis unit.
