While browsing around, I found this article about audio analyzer for Bluetooth measurement. The article mentions that the device does not only do audio measurement, but also offer connection troubleshoot when possible. It sounds helpful because wireless audio is getting more popular lately.
Judging from the technical aspects brought up in the article and the price chart, that's some pretty serious technology. Yes, wireless audio is popular and the more popular it gets, hopefully, prices will go down.
That sounds like a helpful tool. Wireless connection is often troublesome; sometimes because of small errors that we can't tell exactly. I didn't expect we can have such technology in this age!
The article raises really pertinent issues especially because audio connection issues are common for wireless devices. However, looking at the cost of this analyzer makes it seem like a device more suited to device engineers and not the common audio enthusiast.
