Vehicle-mounted audio test method based on cold start

The invention provides a vehicle-mounted audio test method based on cold start. The method comprises the following steps: S1, recording and naming an audio file by an upper computer; s2, sequentially analyzing each audio file recorded in the step S1; s21, analyzing the signal center frequency of the audio file; and S22, carrying out amplitude RMS analysis on the audio file Mx of which the signal center frequency value is a normal value. By adopting the method provided by the invention, the audio performance statistics and the reproduction work of the even fault in the cold start process of the vehicle-mounted audio system can be automatically tested. Manpower is liberated, cost is saved, and operation efficiency is high and simple, so that test efficiency and fault problem positioning analysis progress are improved, and powerful support is provided for product stability. 本发明提供一种基于冷启动的车载音频测试方法，S1：上位机录制音频文件并命名；S2：依次分析步骤S1中录制的每一个音频文件；S21：音频文件的信号中心频率分析；S22：对信号中心频率值在正常值的音频文件Mx进行幅度RMS分析。采用本发明所述的方法，能够自动化测试车载音频系统的冷启动
