Enhanced CD

[Pieoftheday]

What is an enhanced CD? I've just ripped one to my server and whilst its ripped successfully, the CD and my ripper seemed to be having a right old tussle at the start:scratch:

Is it a regular CD with fake boobs ? :eyebrows:

There were some weird cd formats that came out about ten years ago. Popular in Japan I think. It's probably one of them. Can't remember what it was about them that supposedly made them special. Maybe someone else can recall?

Think it has blue book class. Contains audio and data

[Spectral Morn]

SHM CD, Blu Spec CD, Blue Spec 2, HQCD, UHQCD, Platinum SHM-CD all are still CDs but made to a higher standard.

Some info here http://www.cdjapan.co.jp/feature/shmcd_allabout

I would have thought as they are still CDs that there would be no compatibility issues re discs being recorded.

There were also glass cds at one point.

Yeah, I've got 'Einstein on the Beach' for a kick-off.

[Macca]

Really? You actually have one? I think they are worth a few quid now.

I would look very carefully at the insert both front and back and see if it has the normal CD statement . If it does not then it does not meet the red book standards which happened with a number of CD's that had additional digital information that would try and prevent you from copying the disc when you put it in a PC . These faded away and were abandoned but there are still some examples out there.

If the disc does have the CD statement then as noted above it is likely to one of the enhanced foramts that were prevalent in Japan but quite scarce here due to the price premium being asked.

recently bought a newish cd from atlantic that has the copy protection thing added. wont work on pc. it has now worked against them as i wont buy any more of their products.

The CD is a Warner Classics CD, Simon Rattle, Mahler s 9th symphony . The CD and insert says nothing about the format other than stereo DDD ? It was the Amazon listing that mentioned it being enhanced and I only wondered about it when it struggled to rip:)

And emerald green CDs made with dark green polycarbonate in order to enhance the sound of CD.

I think they were supposed to be multi-platform versatile - with an additional data component [e.g. video] for computers to display. The difficulty when ripping is probably that some software can't distinguish between the divide on the ECD separating CD audio and the data band, and so tries to rip the blank bit, which may account for the tussle between disc and computer drive during the ripping process. I don't think I've come across one, perhaps they were limited to the USA [?]

John ,I think you are correct:cool:

It was the Amazon listing that mentioned it being enhanced and I only wondered about it when it struggled to rip:)When was it made? If that's the Birmingham Symphony Orchestra version it is relatively old, though it might have been remastered. If it's the Berlin Philharmonic version - that's more recent, though again might have come out in different versions. There was a also a version with the VPO apparently - from around 1998.

Some while back there were some CDs issued in HDCD format - see https://en.wikipedia.org/wiki/High_Definition_Compatible_Digital - which originated from Microsoft. This was claimed to extend the resolution on some players to 20 bits, yet still be more or less compatible with regular CD players. I had one which created havoc when I tried to rip it (that was a freebie - Horenstein's Mahler 1 from the CFM magazine - good CD but hard to rip). Apparently some rippers are aware of this format and will try to create a 20 bit PCM output, which would be good, while others fall apart and generate some horrendous noises.

Some CDs made for the Japanese market have a wider dynamic range. That is because they don't only use 16 bits of data, but they use equalisation which "proper" CD players should use to turn on analogue circuits inside the player depending on flags in the data stream. Again, I think most rippers would either ignore those flags, or maybe some of the better ones might try to simulate the effects of the analogue circuitry. I only ever had one CD that I know of which had that feature, in the days when I had an original player. One day I put that CD in, and a light came on to indicate that the analogue circuitry had been switched in. I don't know if most modern CD players can detect such CDs and switch appropriately, though the feature is in the CD standard. It was the Japanese part of CD development (Sony?) which wanted that - the Europeans (Philips) weren't bothered.

There have been some other attempts at creating "better" CDs, but I think some were simply done on heavier material to reduce jitter in the reading by the laser, and thus reduce the number of errors which needed to be corrected.

If the Warner CD was made for Japan, it may have some of these (or indeed others, which I don't know about) features.

Try using a different software package to rip it. I heard that dbPowerAmp can cope with most formats.

Might also be worth checking with EAC (Exact Audio Copy) to see if it's possible to make a duplicate disc - though if the original has used some really fancy coding - such as phase shifts in the recording of the pits on the CD, that will either trip EAC up, or be filtered out in the copying.

As mentioned further up this thread, the audio might just be regular, but with other material on the disc, such as programme notes, or even video - hence "enhanced".

Hi Dave it's the Berlin one, one thing I found odd was.title and composer data came up.in chinese which I had to convert manually .I can't do a duplicate copy as I rip cds straight to my nova fidelity x40
