What is the latency on this project? Can you please add it to the README?

This project looks extremely awesome! I'm curious what the general latency is like with it, and am curious if you've measured it at all.

I think it would be a great addition to the README, as it's a useful piece of info for people considering building it. Games and voice calls generally benefit from low latency, so the confirmation that it's <10ms would be helpful.

When I get around to building it, I'll add the stat to the project for sure!

I'd like to know how I can measure that. 🤔

Also it would be nice if you measure it and add the data to the project. Feel free to make a pull request!

You can likely calcuate it by looking at the logic of how the firmware uses buffers and pointers.

You could also measure it directly by feeding the output back in with a microphone or similar, potentially. That would require knowing the latency of the microphone input as well, but would at least offer an upper-bound of the latency.

If I ever build this, I will add that info!
