npm install cloudmersive-video-api-client --save
"dependencies": {
"cloudmersive-video-api-client": "^2.0.1"
}
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);
