Problem
Hello, I am planning to develop a utility software that allows us to stream audio from multiple devices to a single device and microphone audio from the single audio to multiple devices. So how can I implement a Virtual device so that one endpoint can have a Virtual speaker so it can transfer audio to another device via the network and then play it at the same time it should also support a virtual microphone so it can receive microphone data from another device and feed the data to the system.
Why
I need to implement this software so If I have a single Bluetooth device and it is connected to a single device with this software it can receive audio from all devices and send microphone input to all devices.
What I have tried already
I have already looked at A2DP Protocol In windows but I don't know if it supports another laptop instead of mobile and I don't know if there is an API like this in Linux, Also I have looked at jack but don't know what this does exactly or if it well suited for my problem
What I am Asking
How to implement virtual audio device drivers in various platforms(Windows/Linux/Android/MAC) is there any high-level APIs for this task instead of writing our own driver from scratch using platform-specific APIs?
Any Better Plans
Are there any better plans than this without implementing a virtual device driver. Any suggestions are welcome Thanks.
