Disclosure: I'm the author of the blog post.

Not really. What works inside noise canceling headphones is a very different technology, called Active Noise Cancellation (ANC). You don't necessarily need Machine Learning to solve the problem.

The technology described in the blog post is for suppressing the noise which goes from your surrounding environment to the other participants of the call (and vice versa).

What others haven't mentioned and I think is important is that active noise canceling headphones don't try modify your incoming audio. They listen to the outside environment and try to cancel external audio that you'd otherwise hear. For example, listening to a podcast on a noisy bus ride.

This sort of noise canceling tries to remove the unwanted noise that is already mixed in with the wanted sound in the same recording. For example, recording a podcast on a noisy bus ride.

Active Noise cancelling(ANC) headphones are really sensitive to latency.

Take An ANC with 0 latency, that stops cancelling noise at 8 khz, and add a 50 usec latency to it, now will stop cancelling noise at ~1.5 khz.

But This article talks about 20ms latency.
