Re: How Closely Do The Values Of Electrolytic Caps From The Same Lot Match?

In the 60's I was interested in 2R R ladders, so I sorted in a lot of 1K 5% resistors, they came out well matched, better than I presumed. I was told, resistors were sorted at the end of the production line, so the 5% I got were those that did not make it in the 2%. So I had those from the same of t...

It's drawback as an A/D is that it only has SPDIF and AES interfaces which are increasingly hard to find on a PC.
Some PCs do have SPDIF outs but almost none have SPDIF In.
Indeed, I looked all over. This makes the Forcusite very interesting.

If it were me I'd start out with AudioTester with a FocusRite 2i2 gen3.

How does this compares whith using
PCM4222EVM with Audio Tester as you did to measure your "balanced moving coil preamplifier".

Re: got screens?

Enough sensitivity to detect a squirrel would also detects leaves moving in the wind.
You need a better filter.
Movement detection is not good enough, it must add squirrel recognition.

Since I bought a 65" tv that was too cheap to pass up ($399)... I moved the 55" over to my computer desk (nice), and bumped the 44" down to permanent squirrel monitor duty.
This deserves automatic picture analysis for squirrel alert.

We should also seriously consider that Chinese-manufactured masks may actually be contaminated with the virus itself to cause infection.
That was the case with the early test kits.
What are the evidence about this ?
