过零率的计算
1.过零率(ZCR)的音频信号的ZCR是多少的量度oftimes信号通过使用窗函数上述和零如上所述穿过零振幅线由过渡从positiveto ZCR还包括将所述音频信号分成temporalsegments的负或副versa.Theimplementation渡ratefor每个段是使用关系计算如下给出[8] [9]。其中,并且可具有三个可能的值:1,0,-1depending在样品是否为正,零或负的。该值的foreach窗口收集产生具有ZCR特征向量的 ...(3)

16位PCM声音自动增益
对于pcm_s16le波形进行增益 可对以下参数进行调节:
amplitude_threshold 声音波形幅值的阈值,默认为0
sub_frane_limit 子帧数限制,子帧数内的波形被作为整体对待,统一进行放大缩小,默认为0.5秒采样数
headroom dbfs净空高度 默认为-6.18dbfs
max_gain 最大增益,单位分贝,默认为20
noise_floor 噪音阈值,dbfs,默认为-40
