命令行 – 在Windows 2008 Server中从MP3 / WAV文件生成可视化(波形)？

Sox,“瑞士军刀的音频操纵”,可以从声音文件中产生准确的PNG谱图.它几乎播放任何东西,二进制文件可用于Windows.在最基本的层面上,你会使用这样的东西：

sox my.wav -n spectrogram

如果你想要一个没有轴,标题,图例和100px高的浅色背景的谱图：

sox "Me,London.mp3" -n spectrogram -Y 130 -l -r -o "Me,London.png"

如果您只想分析一个通道,Sox就可以接受很多选择.如果您需要您的视觉效果更加冷静,您可以对所得的PNG进行后处理.
