Audio Latency Meter
I hate audio latency, but I also like wireless devices so over the years I’ve been trying several Bluetooth headphones, earbuds and speakers and I always noticed a considerable amount of delay. However, knowing exactly how much latency one device has is very hard, making a comparison too subjective.

I couldn’t find a device that measures audio latency so I decided to create my own. If you want to make one, all the files and instructions are in this instructables article: https://www.instructables.com/Audio-L...
