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 🙏

merge-audio

v1.0.0

Published

一个用于合并mp3音频文件的命令行工具。

Readme

merge-audio

一个用于合并多个 mp3 音频文件的命令行工具,基于 Node.js 和 ffmpeg 实现。

功能简介

  • 支持通过音频文件路径列表批量合并 mp3 文件
  • 命令行一键操作,简单高效
  • 自动调用 ffmpeg,无需手动安装

安装方法

方式一:本地开发环境

在项目根目录下执行:

npm install
npm link

方式二:全局安装(发布到 npm 后)

npm install -g merge-audio

使用方法

1. 准备音频列表文件

创建一个文本文件(如 audio.txt),每一行写一个 mp3 文件的绝对路径或相对路径,例如:

D:/aforever/joinvideo/audio/1.什么是大模型.mp3
D:/aforever/joinvideo/audio/2.为什么学习大模型.mp3
D:/aforever/joinvideo/audio/3.如何学习大模型.mp3

2. 执行命令合并音频

merge-audio -l audio.txt -o output.mp3
  • -l--list:指定音频路径列表文件(必填)
  • -o--output:指定输出文件名(可选,默认 output.mp3)

合并完成后,会在当前目录生成合成后的 mp3 文件。

参数说明

| 参数 | 说明 | 是否必填 | 默认值 | |------|------|----------|--------| | -l, --list | 音频路径列表文件 | 是 | 无 | | -o, --output | 输出文件名 | 否 | output.mp3 |

依赖说明

工具会自动调用内置 ffmpeg,无需手动安装 ffmpeg。

示例

merge-audio -l audio.txt
merge-audio --list audio.txt --output all.mp3

常见问题

  • 路径请使用绝对路径或相对于命令执行目录的相对路径
  • 确保所有 mp3 文件编码格式一致,避免合并后出现异常
