AEC evaluation #15

Closed pkalebu closed 6 years ago

pkalebu commented 6 years ago

How is AEC evaluated? Is it automatically on, or do I have to toggle something to turn it on?

It is on by default. You can use tuning.py of this repo to configure and run python tuning -p to get a list of parameters.

To evaluate AEC, just play any sound through the USB Mic Array and record audio at the same time.
