如何“修剪"； Java，C#或PHP的音频文件(用于浏览器) [英] How to "Trim" an Audio File in Java, C# or PHP (For Browser)

问题描述

我正在尝试创建一个需要此功能的Web应用程序:

I'm trying to create a web application which requires this feature:

假设我有一个.mp3文件，我想选择/上传此文件，然后从0:15到0:30(例如)制作一个新文件，然后另存为新的.mp3/.哇.

Suppose I have a .mp3 file, I want to select/upload this file, and then, make a new file of it from 0:15 to 0:30 (example), and then save as new .mp3/.wav.

由于它应该在Web上运行，所以在PHP中更可取，但是我高度怀疑是否有可能接受Java(Applets)或C#(ASP.NET).

As it's supposed to go on web, would be preferrable in PHP, but as I highly doubt it's possible, Java(Applets) or C#(ASP.NET) are acceptable and highly appreciated.

谢谢.

推荐答案

最好的方法是使用 FFMPEG .有一个 PHP扩展，但是我通常发现，最简单的称呼它是与 exec().

The best way to do this is with FFMPEG. There is a PHP extension for it, but I've generally found that it is easiest to just call it with exec().

ffmpeg -ss 00:00:15 -t 15 -i yourfile.mp3 -acodec copy outputfile.mp3
