Over time, the diversity of audio formats has become extremely rich. MP3 and WAV have also become one of the most commonly used audio formats. However, since WAV has clearer sound quality than MP3, in recent years, more and more people have begun to consider converting MP3 to WAV format. Nodejs has also become a popular programming language, and its emergence has made video and audio conversion easier. In this article, we will explain how to convert MP3 files to WAV format using Nodejs.
1. Environment Settings
Before you start using Nodejs for audio format conversion, you should ensure that you have an available Nodejs environment and some necessary modules. You can download the latest Nodejs from the official website https://nodejs.org/en/.
After properly installing the Nodejs environment, we need to download a few new dependencies. Open the command line and execute the following command in the local folder:
npm?install?fluent-ffmpeg
npm?install?ffmpeg
2. Start conversion
After installing all necessary modules, we can officially start audio format conversion .
First, you need to place the MP3 files you want to convert in a local folder. Then, you can use the fluent-ffmpeg module in Nodejs to convert MP3 to WAV files.
const?ffmpeg?=?require('fluent-ffmpeg');
const?fs?=?require('fs');
//請自行將[audio.mp3]替換成要轉(zhuǎn)換的文件名
ffmpeg('./audio.mp3')
????.toFormat('wav')
????.on('error',?function?(err)?{
????????console.log('An?error?occurred:?'?+?err.message);
????})
????.on('end',?function?()?{
????????console.log('Processing?finished?!');
????})
????.pipe(fs.createWriteStream('./audio.wav'));
You can save and name the above code as audio.js, and then execute the following command in the command line:
node?audio.js
After starting the script, the program will start running , and convert MP3 files to WAV files. The converted files will be stored in local folders.
3. Summary
As mentioned above, using Nodejs to convert MP3 files to WAV files can be said to be a relatively simple operation. You can achieve this by installing Nodejs and using the fluent-ffmpeg module.
So, whether at work, in study, or even in personal life, as long as you need to convert MP3 files to WAV files, the above method will be very useful.

What are the challenges and solutions for maintaining CSS in large-scale applications?
Jun 14, 2025 am 12:15 AM
The key to maintaining CSS for large applications is organizational structure, naming specifications, and tool assistance. First, adopt component management, split styles and implement local scopes to avoid conflicts; second, unify naming specifications such as BEM, SMACSS or namespace prefixes to improve maintainability; third, use PostCSS, stylelint and other tools to achieve automated processing and code quality control. Although these methods are not complicated, they require teamwork and continuous maintenance to be effectively implemented.
How does provide and inject allow for deep component communication without prop drilling in Vue?
Jun 20, 2025 am 01:03 AM
In Vue, provide and inject are features for directly passing data across hierarchical components. The parent component provides data or methods through provide, and descendant components directly inject and use these data or methods through inject, without passing props layer by layer; 2. It is suitable for avoiding "propdrilling", such as passing global or shared data such as topics, user status, API services, etc.; 3. Note when using: non-responsive original values ??must be wrapped into responsive objects to achieve responsive updates, and should not be abused to avoid affecting maintainability.
