How to Convert Audio to M4A in Node.JS

Particularly when using Apple products, M4A files can be used to save your audio with a heightened level of clarity and integrity when compared to the more common MP3. When working with music and other forms of audio that necessitate high quality sound, M4A is the ideal format. We will show you how you can use a Cloudmersive API to optimize your audio files by converting to M4A in Node.JS.

We can begin with our client installation:

npm install cloudmersive-video-api-client --save

Or, you can add this snippet to your package.json:

"dependencies": {
     "cloudmersive-video-api-client": "^2.0.1"
   }

From there, we will call our AudioConvertToM4a function as shown below:

var CloudmersiveVideoApiClient = require('cloudmersive-video-api-client');
var defaultClient = CloudmersiveVideoApiClient.ApiClient.instance;
// Configure API key authorization: Apikey
var Apikey = defaultClient.authentications['Apikey'];
Apikey.apiKey = 'YOUR API KEY';

var apiInstance = new CloudmersiveVideoApiClient.AudioApi();
var opts = {
   'inputFile': Buffer.from(fs.readFileSync("C:\\temp\\inputfile").buffer), // File | Input file to perform the operation on.
   'fileUrl': "fileUrl_example", // String | Optional; URL of an audio file being used for conversion. Use this option for files larger than 2GB.
   'bitRate': 56 // Number | Optional; Specify the desired bitrate of the converted audio file in kilobytes per second (kB/s). Value may be between 48 and 1,411. By default, the optimal bitrate will be chosen automatically.
};
var callback = function(error, data, response) {
   if (error) {
     console.error(error);
   } else {
     console.log('API called successfully. Returned data: ' + data);
   }
};
apiInstance.audioConvertToM4a(opts, callback);

After this, your projects will run smoothly as you are clear to create any M4A file you might need!
