How was the Disney Afternoon CD made? What SPARS code would it have?
See that little code in the upper left corner of the CD cover? It reads AAD, meaning the album was recorded on tape, mixed in the analog domain, outputted to a 2-track master tape, and delivered on CD. (The CD is a downgraded digital copy of the 2 track stereo master tape.) The sound quality of this CD is excellent with a wide dynamic range and an overall very pleasing sound. It was recorded and mixed with great care and I tip my hat to everyone involved. (If this same album were released today, it wouldn’t sound nearly as good as it would be digitally sourced and would be another victim of the
loudness war. The recording engineers back then really knew their stuff.) Seriously, everyone: if I am gushing over a CD release, it’s not faint praise! Rarely have I heard one this good. Kudos, Disney! :wink:
As good as the CD is, the full quality of the master tape can only be heard at home with a vinyl pressing as a compact disc is a limited fidelity playback format by comparison. The best way to most completely capture the original performance is AAA: analog tape recording, analog tape mixing, and a vinyl record for playback.
How is a record made? How do the recording and mixing steps impact the record’s sound quality?A vinyl record is a high fidelity playback system, but it is only as good as its source. Each part of the signal chain along the way must be kept at a high quality in order for the home listener to hear something that does justice to what the songs sounded like when they were played live.
How do records get made?
Watch this video and find out! It’s a fascinating process and yields impressive results. This video uses a digital mix instead of analog tape, but you get the idea.
If you want to see the entire process in great detail from the live recording to the final record playback, take a look at this
vintage 1956 RCA Victor documentary. This is an all-analog process (AAA). While the equipment got more advanced over time, the process is essentially unchanged today and records from even the 1950s can produce gorgeous sound. The LP (long playing record) and the microgroove stylus was invented in this era.
Magnetic reel to reel tape was widely used for recording for the first time. This transformed the humble phonograph disc from a hissy, crackly facsimile of a performance to a wonder of engineering and high fidelity. These are some of the greatest inventions ever created in my opinion and leaves me in awe. I am forever grateful to the scientists, engineers, recording technicians, and everyone involved who worked for years to create and perfect them. Their work lives on and hasn’t been beaten yet.
To make records, we need to transfer information from a magnetic storage medium (tape) to a mechanical one (i.e. grooves in a record). You literally take the audio signal and feed it to a cutting head on a lathe that looks much like a turntable needle, but it translates the audio signal into a mechanical vibration that cuts into a metal disc with lacquer coated on it, often simply called a “lacquer.” The lacquer then goes through a series of electroplating steps before it turns into a stamper that forms melted biscuits of vinyl into a record. If that signal that the cutting head uses is a high quality analog one (preferably the original analog master tapes but is usually a safety copy), the sound will be spectacular. If it’s digital, the experience will be compromised significantly. Here is a video of a
very well known recording engineer explaining his methodology and actually cutting a lacquer. Ironically, Bernie Grundman's studio made the lacquers for this album, too!

(Image from AnalogPlanet.com)Having the lathe use a digital mix to cut a lacquer can only result in three codes: ADA, DAA, and DDA.
DDAYou can get vinyl editions of modern music, but it is recorded and mixed digitally, hence the DDA code. This doesn’t sound anywhere as good as a genuine AAA release. Each part of the chain from recording to playback must be kept at a high quality in order for the listener to get the full experience. For various reasons that I will not get into here, a vinyl release of modern music will still sound better than the CD release of the same song, even though the entire signal chain up to this point is essentially CD quality. DAA would be much the same as the source quality isn’t as good as a tape recording and wouldn’t be helped with analog mixing.
ADAWhat is very frustrating is the ADA release. The recent remastered stereo LPs of the Beatles albums, for example, underwent a ADA process: the original stereo tapes were transferred to 48/24 digital PCM for mixing and cleanup and then that digital mix was used to cut the lacquer. It had a grainy, flat sound. It wasn’t anywhere close to the original pressings. Serious record fans will often avoid these and insist on AAA releases: analog all the way. The studio listened to the fans regarding the digitization of the Beatles stereo mixes. For the mono mixes, the lathe was fed directly with the original analog master tapes! All was well with the world again.
What about an audio cassette? Isn’t that AAA? You are correct! When I heard the Disney Afternoon cassette, it had a bit of that airy, room filling feel that you can get with analog releases. Some cassettes can sound amazing. (The CD still held its own by comparison and I deem it to be a superior experience overall. Cassette tapes vary wildly in quality so this is not unheard of.) While this was clearly AAA, a cassette can’t hold a candle to a record. Let’s keep the signal chain at top quality from start to finish. Not all ‘A’s’ are equal.
You really hate the letter ‘D’. Does all digital stink?No. CDs pale in comparison to records and especially analog tape (and the less said about MP3, the better…) but high fidelity digital options like 192/24 PCM and 2.8 MHz/1-bit DSD recording and playback are out there and can sound great. DSD in particular is stunning (it was invented for the
Super Audio CD (SACD) format) and can rival vinyl playback at times. It can also feature multi channel surround sound mixes that are like the short lived CD4 quadraphonic record concept. It’s that good. While I still prefer vinyl overall, I’d welcome an SACD release of the Disney Afternoon soundtrack. Unfortunately these high quality digital options aren’t being used so we’re still stuck in the 1970s with CD quality.
