Definitely sounds better than I thought it would have and I've watched tons of this guy's videos in the past.
It really distorts his voice / range in some cases, such as when he taps his desk with that orange hammer. The difference there is night and day. It chops out his his natural voice's range. It seems to degrade his voice the more intense the background noise is, such as the leaf blower (lol), but that's reasonable to expect. But at the same time, even the mechanical keyboard has a very noticeable negative effect on his range.
It's one of those things where I wish so much that it worked perfectly, but I couldn't realistically think about using it for any recording work due to things like the above. There's just too many common noises (typing, etc.) that drastically distorts your voice.
9:23 in that video is hilarious though. Have to love Jerry!
I wonder if its the algorithm degrading his voice or if the input sound is already degraded. Is it possible a leaf blower or a hammer would cause enough "noise" to make it so our ears couldnt hear his voice clearly as well? Then when you subtract out the portion of the sound attributed to the leafblower, youre hearing the parts of his voice that werent being jumbled by the leaf blower?
Hard to say because softer noises like typing still makes his voice sound like it's cutting out unnaturally. It's like the frequencies are being subtracted out of his normal tone, but it's more subtle than the leaf blower so you may not notice it without good headphones. It makes him sound very choppy and mechanical.
With the leaf blower I suspect that when it gets too close the microphone/ADC is saturating, which clips his voice. I wonder if it would've sounded better had he attempted to lower the gain on the microphone.
