Now with <a href="https://polymaths.social/tags/oled" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>OLED</span></a> panels, this effect (I surmise) is even more pronounced, although I no longer get that feeling, probably because I require reading glasses for close-up viewing, which makes <em>everything</em> feel a little artificial.</p><p>(I think I also just got used to it, whereas it was noticeable when the effect (no longer being able to see pixels between you and the subject of the image) was new).</p><p>I think the biggest problem with video chats is the bandwidth still just isn't there. It might be better with FaceTime, but as I haven't used Apple products in nearly five years, I can't tell. In my experience, video chat is just a blotchy mess with only the appearance of the subject, not a faithful representation.</p> <p>I'm not a sound engineer, but I've dabbled in sound in the computer space for 35 years. My favorite thing to do with my Macintosh SE in 1990 was to download or copy (from friends) new sound files, like Captain Kirk saying "Scotty, beam me up!" (which he actually DID say, but only in the movies).</p><p>My Macintosh SE with it's primarily CPU-driven sound system was capable of 8-bit audio at up to 22KHz samples. That was enough to give the impression of the sound, and tape-quality music, but not much more.</p><p>Four years later, I got a 486 PC and saved up a few months to get a Creative Labs <a href="https://polymaths.social/tags/soundblaster" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>SoundBlaster</span></a> AWE32, which I paid for with $300 of my own hard-earned cash. That was a crazy stupid expensive card, and a $100 card would've done everything I needed. XD</p><p>This new card had "CD Quality" sound, so 16-bit samples @ 44.1 (or was it 44.8) KHz. Since PCM audio is basically just recording the speaker position, that means that 44KHz recordings can reproduce up to 22KHz sounds, which is the upper range of a youngster, and beyond what someone my age can hear.</p><p>But of course, at that frequency, the sine wave is literally only represented by two data points, so there should be a real loss of fidelity compared to something like 4400 Hz, for which there would be 10 data points with which to reconstruct the sound wave.</p><p>And then add MP3 to <em>really</em> mess everything up.
