Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

例子

请参考: ./docs/demo.html 或者 点击我

使用方法 已支持语法提示

  1. script引入
    下载index.js 正常引入
  2. require
    npm install audio-visualization
    require('audio-visualization');
  3. webpack / vue
    import AV from 'audio-visualization';
const av = new AudioVisualization({
  url: './1.mp3',
  loop: false,
});
// 调用 setVoiceSize 可设置 声音大小
av.setVoiceSize(100);
// 调用 setFftSzie 可设置 frequency长度 
av.setFftSzie(128);
// 调用 play 传入 回调函数 
// - frequency 可获取到频谱
// - currentTime 获取当前播放进度
// - audiostate 得到当前状态
av.play(function ({ frequency, currentTime, audiostate }) {
  console.log(frequency,urrentTime, audiostate);
});
// 单独调用直接启动不会执行回调 建议调用不要直接调用而是 调用 play
start(): void;
// 暂停音频内容的进度.
suspend(): void;
// 重新启动一个已被暂停的音频环境
resume(): void;
// 停止后无法再次启动,请慎重
stop(): void;
