DJ CD players that do this have been around for years.

I've never fainted, so I wouldn't know.

Yes, if you try this at home, don't look at the laser!

Yes I've heard tell that the DACs in some of the very early CD players were quite poor, but personally I've never heard a CD player that sounded bad to me. My first experience with CDs would have been in the early 1990s. Even cheapo CD players sound fine to me!

I'd not heard of a tempophone, but now I desperately want one!

you can get software that simulates itBasically, it works by chopping up audio into small grains, anywhere from 10 to 80 milliseconds. Speeding it up skips some grains while crossfading, and slowing it down loops some grains, again while crossfading. You can get software that simulates it.

Players with "skip protection" or "shock protection" will do this, typically portable and car players. They read data from the disc faster than it's actually required to be passed to the DAC, buffering up the excess data. They have big buffers, so the disc is being read about 30 seconds or even more ahead of the audio that's actually being played. If the data being read from the disc is interrupted for any reason, they can just continue to play from the data already loaded into the buffer, then the buffer can be topped back up once the disc reading resumes. Some players even read a chunk of audio data into the buffer, then stop the CD spinning completely until the buffer is nearly run out, mainly to save on battery usage.

I think you just see the same thing but in reverse, i.e., some parts would be skipped, since this is not a tape/vinyl

@meow_meow_J yeah it did skip a bit

It was my best audiophile player. I sacrificed it for the purposes of a KZbin video.

well it still works properly if you dont touch it

"it was" 😞😞😞

It sounds good, like a vinyl record player. ​@@timf-tinkering

Must have lived in blue city.

love yasunao tone

I’d recommend Oval’s Do While, which involves the group damaging CDs and putting them back together. The music also sounds a lot more pleasant

Now I have a new artist to check out…

It's "That Old Pi-Anna Rag" performed by Russ Conway.

The track is "That Old Pi-Anna Rag" performed by Russ Conway, from a CD called "The Best of Russ Conway"

More of this!

They're stored alternating in the stream with a preamble identifying the channel, so they're affected the same way.

Kind of sounds like a tempophone

mhm

I actually think it doesn't even slow down at all, it's just that the bitrate gets lower or something. Sounds a bit like old granular samplers

@@aheendwhz1it’s purely digital, so you’re not actually slowing down the audio… but as the bitrate drops the error correction has to be more and more aggressive, until it becomes noticeably wrong… then at some point it’s too slow and the audio stops

Yes, I'm kind of surprised it coped so well. I would have thought it would give up and crap out as soon as the buffer underran, but it bravely soldiered on.

not all CD players have buffers. Buffers aren't actually apart of the red-book standard. Some sophisticated/later cd players (mostly car or portable players but even early portables lacked buffers) have buffers but not all cd players have buffers. Not all CDs are made of plastic alone either. Pre-recorded CDs actually have a layer of metal in the center. CD-Rs however, are made entirely of plastic with a dye which is where you probably got confused.

@sam_64 no, CD-Rs still contain a layer of metal. It’s usually either gold, silver, or a silver alloy.

​@ you're right actually

@ yeah I used to microwave them for fun 😂
