控制 mp3 文件的音频速度 [英] Controlling audio speed of a mp3 file

问题描述

我想在我的网站上播放 mp3 配乐，并使用滑块按百分比控制配乐的速度.我想知道如何仅使用 HTML(5) 和 JavaScript 来完成此操作.我一直无法找到任何示例或教程，任何帮助将不胜感激.

I would like to play a mp3 soundtrack on my website, and manipulate the speed of the soundtrack by a percentage using a slider. I'm wondering how this could be done with only HTML(5) and JavaScript. I haven't been able to find any examples or tutorials, any help would be greatly appreciated.

推荐答案

是这样的:

myaudio=document.getElementById("audio1");
myaudio.playbackRate=0.5;

这是演示音频和视频都具有可以设置以更改播放速率的属性的基础知识.滑块和其他东西的实现，你可以根据需要使用jquery来实现.

This is the basics to demonstrate that audio and videos both have property you can set to change the playing rate. The implementation of sliders and other things, you can achieve using jquery based on how you want it.
