- brazzy 2y agoEcho cancellation was implemented in the analog domain 50 years ago at the least. It's wild to see someone assume this kind of thing requires machine learning algorithms.
- lazide 2y agoI'm guessing they were (rightfully) pointing out it's still harder than just ignoring any input if there is a given tone. Which yeah, it is. I'm assuming they'd prefer to use that for things like advertisements though, since the cancellation approach lets them ‘listen’ while still talking/playing music/etc.
