如何合并多个m4a或音频文件并将其附加到音频标签，并正确显示controller上的时间
[英]How to merge multiple m4a or audio files and attach it to audio tag, and show the time on controller correctly
问题描述
<audio id="audio" controls>
<source src="Countdown.m4a" type="audio/x-m4a">
Your browser does not support the audio element.
</audio>
This is the html element, I want to repeat "Countdown.m4a" three times, and as "Countdown.m4a" is 5 mins longer, the controller slider should show 15 mins instead of 5 mins.
这是 html 元素，我想重复“Countdown.m4a”三次，由于“Countdown.m4a”长 5 分钟，controller slider 应该显示 15 分钟而不是 5 分钟。
How to achieve this?如何做到这一点？
tried using, but not able to modify control slider length.尝试使用，但无法修改控件 slider 的长度。 Tried finding how we can merge the files using js, but nothing I could find online.试图找到我们如何使用 js 合并文件，但我在网上找不到任何东西。

Because all a/v media is inherently more complex and involved than it seems (meaning concatenating media is more problematic than you might think for a whole bunch of reasons), your best bet would be to concatenate sound by doing all your work server side, where you can leverage command line apps like ffmpeg.因为所有的 a/v 媒体本质上都比看起来更复杂和复杂（意味着连接媒体比你想象的更成问题，原因有很多），你最好的选择是通过在服务器端完成所有工作来连接声音，您可以在其中使用命令行应用程序，例如 ffmpeg。
