In this short tutorial, we will learn how to insert audio in PDF using Java. It contains all the information required to establish the environment, a step-by-step approach for writing the application, and a running sample code that demonstrates the process to add audio to PDF using Java. It also shares a number of options to customize the sound annotation added to the PDF file.

Steps to Embed Audio File in PDF using Java

1. Set the IDE to use Aspose.PDF for Java to add audio
2. Load the target PDF file using the Document class object and access the desired page for adding audio
3. Create a SoundAnnotation object and set desired properties along with the audio file name
4. Add this sound annotation to the annotations collection on the selected page
5. Save the resultant PDF file having an embedded audio file in it

These steps define the process of how to add audio to PDF using Java. All the important resources are identified like the library to be added, classes, methods, properties to be utilized, and a sequence of steps for writing the application. It can be observed that no third-party tool like Acrobat Writer or any other application is required to write this application.

Code to Embed Audio into PDF using Java

The aforementioned sample code demonstrates the process to add audio file to PDF using Java. The process is quite simple first load a PDF file, get access to one of the pages where audio is to be embedded and then create a sound annotation that requires the reference to the page, a rectangle where the audio symbol will be placed, the media file, color, title, subject, etc. You can not only set a number of other properties of sound annotation but also add a variety of other annotations like 3D annotation, widget annotation, rich media annotation, and movie annotation to name a few.
