在 PHP 中自动修剪 mp3
有没有办法在 PHP 中自动将上传到网站的 MP3 修剪为 30 秒(或其他长度)?如果没有，是否有任何好的第三方服务可以集成(对用户透明)以达到相同的效果?
Are there any ways to automatically trim an MP3 uploaded to a website to 30 seconds (or some other length) in PHP? If not, is there any good 3rd party services that could be integrated (transparently to the user) to achieve the same effect?
谢谢.
推荐答案
你可以试试 PHPClasses 上的 MP3 类.它具有以下示例:
You could try the MP3 Class on PHPClasses. It features the following example:
require_once './class.mp3.php';
$mp3 = new mp3;
$mp3->cut_mp3('input.mp3', 'output.mp3', 0, -1, 'frame', false);
在这种情况下，帧"可以替换为秒"，以根据时间帧进行剪辑.
In this case, the 'frame' can be substituted with 'second' to base the cut on a time-frame.
