Tech: high quality cd copies

I understand that it is allowed to make a backup copy of a cd you own.
I am also told that the copy you'd get by putting it in a computer, ripping and burning is compressed and this is why it doesn't play on our dance club player.
Can someone give me an idiots guide to doing it without loss of information.

Record as .wav not .mp3

It's illegal, but I won't tell...

Re "It is allowed": you need to say where you are, allowed in some jurisdictions, not in others. Some jurisdictions allow for private use as backup, but the semi-public use in a dance club might or might not be included.

"...copy is compressed, etc" It can be, but need not be.

If you advise us what equipment & software you have available then relevant advice will be forthcoming for sure.

Your dance club player is probably being asked to play an MP3 disc, but unable to do so. A different player may well be able, but burning a new disc in CD format is most likely to work out cheaper.

Don't most CD burning programs give you an option to copy a CD, so the copy is of the same type as the original?

Anyway, certainly don't rip to MP3, and even if you RIP to WAV, make sure the copy is an audio CD and not a computer CD, because it's quite possible to make a CD-ROM with .WAV files on it which also isn't readable by a normal CD player.

As for legality, most CDs come with a notice prohibiting unauthorised "public performance", which means your dance club may be infringing a copyright notice before you even start making copies.

Most home PC software suites usually include something like Nero,
or you can download highly rated free software eg, "Exact Audio Copy"

http://www.exactaudiocopy.de/

These 'audio grabbers' tend to work most effectively if you copy the CD
as an entire single 'image' file eg .iso.

Copy and burn at reliable slow disc speed eg. 4x. to avoid errors,
and tick option for disc verification.

An interesting point, I don't know current availability of products,
but 10 years ago High Street shops readily stocked Hardware CD Copiers.

Devices containing two CD Roms. A player and a burner.

CD's were copied on the fly at high speed..
I don't know how reliable the copy process was in terms of read and write errors,
or how they coped with copy protected CDs ?

I bought one from Staples for £150, then not long after the price dropped in clearance sale to £50, so got another.

They're still boxed up in storage somewhere as the band that required a large fast supply of cheap demo CDs
went into sudden hibernation due to the singer getting pregnant..

Just had a google out of nostalgic curiosity.

These products are still on sale..eg, convenient possibly foolproof CD copier for just over £100..

You require a dedicated CD resorder and "Audio"" blanks. Computers will not make a perfect copy! The tend rip data to the computer hard drive then export it back to the CDR converting the format each time.

iTunes is available as a free download from the Apple website. It allows you to import CDs into the iTunes library in the format of your choice. Setting up the contents of the CD in a "playlist" allows you to burn a CD in the format of your choice. If you choose this method, I would advise getting a printed guide such as the "Missing Manual" series, as the Apple "Help" pages assume much more than a basic knowledge; the books give you a step-by-step run-through of the processes.

The "Audio" CDs described above were a supposedly consumer-friendly option which appeared briefly about fifteen years ago. Even when the system was introduced, the discs were extremely hard to find and much more expensive than computer CD-Rs (Consumer-Audio CD-Rs still available through eBay or Amazon - they disappeared from High-Street stores years ago) and required dedicated copier machines, as described in Hookey Wole's post (11.43). The copier described in his 11.52 post is a different beast entirely. It uses computer-type CD-Rs, and in my experience (two different Acard machines), "possibly foolproof" is wildly optimistic.

I should have said iTunes is available for both Mac OS and Windows; machine requirements on the website.

For what it's worth, Woodsie is spouting utter crap.

Not necessarily, oh-unnamed-guest. It depends on how many CD/DVD drives you have and if it moves it directly or puts it on the hard drive first. He's describing a less sophisticated computer setup (one CD/DVD drive). And if you're not careful, the computer will convert the files in that process.

Hi Mo,
Why not play the original CD on your dance club player and play the copy on your P.C ?

I have more or less stopped burning CDs & DVDs completely since advent of pocket media players
and affordable USB hard drives & memory sticks.
I guess that's fairly typical for most audio visual enthusiasts.

Last time I checked stacked up boxes of recorded discs
so many of the earlier ones had already started to visibly deteriorate
despite being stored carefully in cool dry dark room.

This thread has also reminded me of a pair of high quality Pioneer CD Audio recorders I've got boxed up somewhere.
Can't have used them for about 8 years,
since finishing off my last pot of expensive Audio specified discs.
