librosa 的 write_wav 函数是一个非常实用的工具,可以帮助我们方便地保存音频数据为 WAV 文件。WAV 文件格式包含了音频信号的元数据以及音频数据,相对于其他音频文件格式,如 MP3,提供了更高的音频质量。librosa 库不仅提供了 audio signal generation、频谱分析、音量 normalization 等常用功能,而且它的 write_wav 函数...

librosa.output.write_wav doesn't accept int16 typed arrays, while it worked before. I found this is caused by #616, f3114f2. Is this an intentional change or a bug? Steps/Code to Reproduce In [1]: import librosa; import numpy as np In [2]: librosa.__version__ Out[2]: '0.5....
WAV格式没有压缩，播放MP3之类的还要解压，额外需要解码库，如何程序只是要一些提示音，就可以使用WAV格式...
The Wave API Manager never calls the WAV_Write function, so this routine may be empty and have an arbitrary return value. WAV_Write is a required stream interface driver function, but the function WAV_IOControl handles all data communication. The audio MDD implementation always returns 0....

each with a single f-key. SHIFT-F2 through SHIFT-F11 initiate the recording process, ESCAPE ends the recording, and F2 through F11 transmit the recorded WAV file. If that is all you want WriteLog to do with recorded audio, then there is nothing more for you on the rest of this page....
wavwrite(signal,fs,'test.wav'); data =wavread('test.wav'); plot(t,data,'r--'); 结果: 幅度放大之后,信号失真,也难怪频率听起来不同了。看一看wavwrite特性: 为了让信号不失真,可以采取两个办法:1)信号归一化;2)利用NBITs=32设置: 修改: ...
