How to Convert an Audio File to .WAV using JavaScript

Lossy audio formats like MP3 won’t cut it for a certain quality of media production. When you want to retain the absolute quality of your audio file, .WAV format is the way to go.

If you find your website or application is in need of consistent .WAV conversions, it’s time to think about implementing a .WAV conversion API. We’ve got you covered — following instructions below, you can easily take advantage of our Audio to .WAV Conversion API with ready-to-run code examples to structure your API call with JavaScript.

Your first step is to install the jQuery library. Run the below command:

bower install jquery

After that, copy & paste the below audio conversion function. Once you satisfy the basic parameters for this operation (including both the input audio file & your Cloudmersive API key), you’re all done:

var form = new FormData();
form.append("inputFile", fileInput.files[0], "file");
var settings = {
     "url": "https://api.cloudmersive.com/video/convert/to/wav",
     "method": "POST",
     "timeout": 0,
     "headers": {
          "fileUrl": "<string>",
          "sampleRate": "<number>",
          "Content-Type": "multipart/form-data",
          "Apikey": "YOUR-API-KEY-HERE"
     },
     "processData": false,
     "mimeType": "multipart/form-data",
     "contentType": false,
     "data": form
};
$.ajax(settings).done(function (response) {
     console.log(response);
});
