Audio Conversion API: Convert File to M4A Format using Java

Our Audio APIs make a few of the most common file conversions easy. With code provided below in Java, you can seamlessly take advantage of our M4A Conversion API, which supports a variety of input audio formats (uses 1 API per 10 mb of file size).

Begin by installing the Java SDK with Maven. Add a reference to the pom.xml repository:

<repositories>
    <repository>
        <id>jitpack.io</id>
        <url>https://jitpack.io</url>
    </repository>
</repositories>

Now add one to the dependency:

<dependencies>
<dependency>
    <groupId>com.github.Cloudmersive</groupId>
    <artifactId>Cloudmersive.APIClient.Java</artifactId>
    <version>v4.25</version>
</dependency>
</dependencies>

Wrap it up with the import classes and, finally, the audio conversion function:

// Import classes:
//import com.cloudmersive.client.invoker.ApiClient;
//import com.cloudmersive.client.invoker.ApiException;
//import com.cloudmersive.client.invoker.Configuration;
//import com.cloudmersive.client.invoker.auth.*;
//import com.cloudmersive.client.AudioApi;
ApiClient defaultClient = Configuration.getDefaultApiClient();
// Configure API key authorization: Apikey
ApiKeyAuth Apikey = (ApiKeyAuth) defaultClient.getAuthentication("Apikey");
Apikey.setApiKey("YOUR API KEY");
// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)
//Apikey.setApiKeyPrefix("Token");
AudioApi apiInstance = new AudioApi();
File inputFile = new File("/path/to/inputfile"); // File | Input file to perform the operation on.
String fileUrl = "fileUrl_example"; // String | Optional; URL of an audio file being used for conversion. Use this option for files larger than 2GB.
Integer bitRate = 56; // Integer | 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.
try {
    byte[] result = apiInstance.audioConvertToM4a(inputFile, fileUrl, bitRate);
    System.out.println(result);
} catch (ApiException e) {
    System.err.println("Exception when calling AudioApi#audioConvertToM4a");
    e.printStackTrace();
}
