摘要
该文主要是对于蜂鸣器的出厂测试中进行声音频率和相对响度自动化测试实践,通过声音的采样,将模拟音频转化为数字音频。采用FFT(快速傅立叶变换)算法,对数字音频进行频率和响度的分析。
This paper mainly carries out the automated test of sound frequency and relative loudness in the factory test of the buzzer.Through sound sampling,the simulated audio is transformed into digital audio.FFT（fast Fourier transform） algorithm is used to analyze the frequency and loudness of digital audio.
