音频信号采集设备的检测方法与应用

Detection Method and Application of Audio Signal Acquisition Equipment

阐述利用采集到的音频信号提取音频信号中的总帧数为N帧的时域音频数据,计算其能量值并通过比较其与预设的能量阈值的大小关系,若出现能量值大于预设阈值就需要转换成频域音频信息,提取频域音频数据的每一帧谱峰频率,判断谱峰频率是否呈现稳定。计算得出稳定状态,根据结果分析音频信号采集设备是否存在异常连接现象。

This paper expounds the use of the collected audio signal to extract the time-domain audio data with a total number of N frames in the audio signal, calculate its energy value, and compare its relationship with the preset energy threshold. If the energy value is greater than the preset threshold, it needs to be converted into frequency-domain audio information, extract the spectral peak frequency of each frame of frequency-domain audio data, and judge whether the spectral peak frequency is stable. Calculate the stable state, and analyze whether the audio signal acquisition equipment has abnormal connection according to the results.
