The Compact Disc: An Introduction

I'd like them to team up. Bring Techmoan and Vwestlife into the party.

Awesome, a blooper outro ;)

Excellent as always Alec. You have taught me things I didn't know I was interested in until you taught me about them. :-) I spotted the flash at 14:32, but only people like me do. One thing, might I suggest you use cuts rather than sudden, blinding, "dip to white" transitions. There is nothing more 'invisible' then a properly timed cut.

Do players only read one track of pits at at time? I thought I read somewhere that later machines would read bands of tracks at a time using an imaging array. The advantage would make the player nearly bump-proof for use in cars and when walking around. My Sony CD walkman in 1989 came with a car adapter kit that included a compact cassette interface and a spring cushioned and damped docking mount for installation in my car. It was wibbly-wobbly when installed but it wouldn't skip when I hit a bump. A big deal back then.

I hope the next episode will cover how the laser is able to track and keep focus.

There were a couple of strange render bugs, indeed. It's a weird thing that Premiere does occasionally. See, I saw those glitches when I was playing through the edit, but when moving frame by frame on the timeline they weren't there. So I assumed they were just a preview rendering issue, but they turned up in the rendered file. Thus usually happens when adding a cross dissolve to a masked object, which is what happened this time. Not big enough to bother working out, though. I think in the future I'd need to delete the object in the timeline and re-insert it.

There is a black bar blinking in the left side of the screen right before the big black logos show up (i.e. the Compact Disc logo in the piece about dual disk). It happened at least one more time throughout the video. It only appears for one frame on 1080P version (I did not check any other versions). I noticed it by eye and captured here: <a href="https://imgur.com/a/H2SQo3T" rel="nofollow noopener" target="_blank">https://imgur.com/a/H2SQo3T</a> Other than that, amazing material, thank you for diving so deep into the subject!

Haha! Loved the bloopers (and cheesy music) in this one. You went ahead and made my day.

At least it's been updated to support a 24bit 192khz 2 channel stream..... not that it's very meaningful

Since you're talking about Sony and Philips, it might be a nice tidbit to mention S/PDIF and why it's such a strange-looking acronym with a slash in the middle of it. Actually, a whole episode on S/PDIF, TOSLINK, and coaxial digital audio cables might be pretty sweet. Especially interesting would be to talk about how S/PDIF was later retrofitted to support multichannel digital audio but only up to the bitrate of the original uncompressed stereo PCM audio stream (so no 5.1-channel PCM over S/PDIF, unlike the monstrous PCM streams we can push over HDMI nowadays).

Did you ever nail Sony: "The company that either makes runaway successes or disastrous failures." Yep, that's Sony.

What will all the streaming addicts do when the cloud is hacked, the content is seriously monetized, and the servers fail? Hmmmm ... be happy they still have the physical media.

"Floaters" does have a really retro, 80s film "just before the credits" feel to it - I think it works great.

Man, I JUST finished up LGR's video on the "multi-laser" reader from Kenwood. Technical deep dives are the best.
