audio - 将大量 wav 文件拆分为小部分

Question

我有大量 wav 文件(超过 50 000 个)，我需要将每个 wav 文件拆分为 10 秒长的部分。几乎不可能一一做到，所以我的问题是:有没有办法在 ffmpeg 或例如在 sox 中做到这一点？我是业余爱好者，所以我需要确切的指示。如果可以的话，请像写假人一样写:)...(我是 Windows 7 用户)

Here is my try with sox

谢谢!

Answer 1

几天前我有完全相同的任务。我更喜欢在 Linux 操作系统机器上做，但我必须在 Windows 机器上做一些演示，所以我使用 SoX 编写了这个批处理文件:

@ECHO OFF

rem Author: PetarF, 2017-07-01, v0.1
rem
rem Example of how to do batch processing with SoX on MS-Windows.
rem In this example, for every .wav file in folder the splited .wav file ends up in a folder called as original file without extension
rem In my case, this file has to be run as administrator
rem
rem USAGE: 
rem Place this file in the same folder as sox.exe (& rename it as appropriate).
rem Place .wav files that has to be splited in same folder as sox.exe

ECHO Split started
cd %~dp0
for %%A in (*.wav) do (
    mkdir %%~nA
    sox %%A %%~nA/%%~nA_.wav trim 0 10 : newfile : restart
    echo Created folder %%~nA with splited files
)
echo SoX has splited files...
