I am developing an app using native development in Android Studio, and I would like to add functionality for streaming WAV files. Specifically, WAV files are generated in real-time and need to be played sequentially on the Magic Leap 2 device. I have referred to the audio-input sample app from the C API folder of ML SDK, but I am not very familiar with the functions used in it, as well as how to store and manage the audio data. I am seeking guidance on the C++ code that handles audio playback on the device, or if there are more detailed resources or documentation on audio playback, that would be very helpful.

**ML2 OS version** : latest  
**MLSDK version** : latest  
**Host OS** : Windows

Since the Magic Leap 2 supports audio playback using the standard Android 10 audio APIs, you can implement your functionality using Android’s native `AudioTrack` class for streaming and playing WAV files.

Here are some useful links to resources and documentation that can help you with your project:
