librosa 加载与 scipy.io.wavfile 读取的区别 [英] Difference between load of librosa and read of scipy.io.wavfile

问题描述

我对librosa的load函数和scipy.io.wavfile的read函数的区别有疑问.>

I have a question about the difference between the load function of librosa and the read function of scipy.io.wavfile.

from scipy.io import wavfile
import librosa

fs, data = wavfile.read(name)
data, fs = librosa.load(name)

导入的语音文件是同一个文件.如果运行上面的代码，两个函数出来的数据的值是不一样的.我想知道为什么数据的值不同.

The imported voice file is the same file. If you run the code above, the values ​​of the data come out of the two functions differently. I want to know why the value of the data is different.

推荐答案

来自 librosa.core.load:

将音频文件加载为浮点时​​间序列.

Load an audio file as a floating point time series.

音频将自动重新采样到给定的速率(默认 sr=22050).

Audio will be automatically resampled to the given rate (default sr=22050).

要保留文件的本机采样率，请使用 sr=None.

To preserve the native sampling rate of the file, use sr=None.

scipy.io.wavfile.read 不会自动对数据重新采样，如果文件中的样本是整数，则不会将其转换为浮点数.

scipy.io.wavfile.read does not automatically resample the data, and the samples are not converted to floating point if they are integers in the file.
