NodeJS-读取music-metadata

music-metadata npm 仓库
music-metadata Github 仓库

介绍

用 music-metadata 来读取音频文件的一些元信息, 如歌曲名, 歌手等. (前提是文件里有这些信息)

安装

npm install music-metadata

示例

import { parseFile } from 'music-metadata';
import { inspect } from 'util';

(async () => {
  try {
    const filePath = './music/test2.mp3';
    const metadata = await parseFile(filePath);

    // Output the parsed metadata to the console in a readable format
    console.log(inspect(metadata, { showHidden: false, depth: null }));
  } catch (error) {
    console.error('Error parsing metadata:', error.message);
  }
})();

• parseFile() 是一个异步函数, 接收音频文件路径

输出如:
