代码中,librosa.samples_like仅用来获取音频帧的下标,librosa.frames_to_time用来根据音频帧的下标转化为时间,这两个函数的返回值是ndarray类型。 代码运行结果如下: y = [-0.00856018 -0.00930786 -0.00827026 ..., -0.03897095 -0.03567505 -0.03329468] 总帧数=170880,采样率=48000,持续秒数=3.560000 samples = [...

采样使用y每个元素的下标除以采样率sr获取帧与帧的时间间隔的方法可能会更简单,本文仅是使用librosa.frames_to_time和librosa.samples_like来实现,代码在Ubuntu中实现,如下。 代码语言:javascript 复制 importlibrosa audio_full_name=r'/mnt/hgfs/win10_linux_shared_file/audio_larger.wav'y,sr=librosa.load(audio...

High density time division busses suffer from many problems, one of which is that impedance discontinuities cause signal reflections to occur along the bus. These reflections, in turn, affect the settling time and noise margins of the bus and thus reduce the time "window" in which valid ...
