How to Convert an Audio File to M4A format with JavaScript

Processing audio files on your website? If you’re looking for a super high-quality compressed file option, M4A is an excellent way to go. Though not nearly as widespread in its popularity as MP3 files are, M4A is, for one thing, the chosen format for iTunes music — and playback is supported on virtually all of the most common audio programs. M4A files come out a little bigger than MP3, but that relative file size in turn represents a comparative step up in output audio quality (which is particularly suitable for the high-end requirements of, for example, podcast and video productions).

With our Audio to M4A Conversion API, you can build M4A conversion into your website, and put those conversion needs to rest. Follow instructions below to structure your M4A conversion API call with ready-to-run code examples provided in JavaScript.

To begin, let’s first install the jQuery library using the following command:

bower install jquery

Next, let’s include the audio conversion function. Within the function, be sure to satisfy the necessary parameters, including the input audio file for conversion & your Cloudmersive API key for authentication:

var form = new FormData();
form.append("inputFile", fileInput.files[0], "file");
var settings = {
"url": "https://api.cloudmersive.com/video/convert/to/m4a",
"method": "POST",
"timeout": 0,
"headers": {
"fileUrl": "<string>",
"bitRate": "<integer>",
"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);
});

If you’re short a Cloudmersive API key, you can easily get one by registering a free account on our website (Home — Cloudmersive APIs). Just like that, your M4A conversion needs are a distant memory.
