An audio testing system includes an acquisition unit, an input unit, a first analysis unit, a second analysis unit, and an output unit. The acquisition unit obtains an audio signal played back by the audio player. The input unit generates a first input signal and a second input signal. The first analysis unit analyzes the acquired audio signal with a first analysis method in response to the first input signal to obtain performance parameters of the audio player. The second analysis unit analyzes the acquired audio signal with a second analysis method in response to the second input signal to obtain another set of performance parameters of the audio player. The first analysis unit is more accurate than the second analysis unit, and efficiency of the second analysis unit exceeds that of the first analysis unit.
