Streaming Audio via Bluetooth my Osx to PC

I found an app for make PC ***** an takes audio from other android devices. However, when i connect with Mac it doesn't work. I use airplay for now but there are latency and quality problems. I have Late 13 Macbook Pro which uses airplay 1 technology. It is slower than newer one. My Wifi router in my room but as i said i want to connect with bluetooth. Why this problem appears. How to work on this?
