Java - detect if application sound

Question

For my weekend weekend project, I am trying to create a simple program that waits for a program / process to output any sound, and when / if it does, do something.

in pseudo code:

if (application.outputsSound()) { /* Do something */ } 

For starters, it can be any sound coming from a specific application, but if within the reason it detects a certain sound based on the stored audio file, that would be really cool.

My thoughts: I suppose I need some kind of native library (JNI / JNA), but since I'm new to this, it would be very convenient if someone could point me in the right direction.

On Windows, you can use the IAudioSessionEnumerator interface

Although this is not ideal, as third-party audio stacks will not be displayed, such as ASIO.

On Linux, it depends on which environment you are using.
