Abstract

The application is applicable to the technical field of audio analysis, and provides a crosstalk detection method and system and an audio analyzer. According to the embodiment of the application, themethod comprises the steps: outputting a left channel signal source and a right channel signal source with different waveforms to tested audio equipment; collecting a left channel signal and a right channel signal output by the tested audio equipment; acquiring waveforms of the left channel signal and the right channel signal; and determining whether crosstalk occurs in a left channel and a rightchannel of the detected audio equipment according to the waveforms of the left channel signal and the right channel signal. Therefore, the detection efficiency is high, and the detection result is accurate.

Description

technical field [0001] The application belongs to the technical field of audio analysis, and in particular relates to a crosstalk detection method, system and audio analyzer. Background technique [0002] All kinds of audio equipment such as audio power amplifiers, speakers, headphones, etc. need to undergo audio analysis and testing before leaving the factory, and they can only leave the factory after passing the test. The main indicators to measure the qualification of audio equipment usually include frequency response characteristics, harmonic distortion, signal-to-noise ratio, dynamic range, etc. For audio devices with left and right channels, such as speakers and earphones, it is usually necessary to detect whether crosstalk occurs in the left and right channels. The existing crosstalk detection method is to manually listen to whether the output sounds of the left and right channels are normal. It is difficult to accurately distinguish whether crosstalk occurs in the l...
