hi
i bought as soon as it was release the last radiohead's A Moon Shaped Pool in a local store
and after i bought even the vinyl
listening it with Sennheiser HD598 & grado SR225e i can head lots of cracks and the audio is clipped on my cd player
i tried to rip with several software like eac and audition cc too
i don't know if i have a bad copy because i bought as soon as it was released
does somebody own this album?
is my cd or i was recorded badly?
and is there a way to fix it? (i don't expect micracle )
i pretty sad because it's one of my favorite album
i just ripped to flac and look the wave and spectral view
look the screenshots ,it's the first track
thanks

I'm afraid that if this is a legitimate CD release, they're all going to be like it. It's not necessarily the studio's fault at all - it's the way a lot of 'popular' material is 'mastered' - basically to make it as loud as possible so that it stands out on the radio, or whatever. And even if you could remove it, there's no way you can restore the peaks on that much clipping without reducing the overall level of the track significantly.
Mind you, it's not that clever a recording, and clearly somebody has had to do some work to it before it was released. If you look on the spectral display at the point where 16kHz is (near the top), you'll notice that there's a slightly darker band right across the track. This means that somebody's run a filter across the whole thing. A few years ago I discovered (the hard way) that if you have something like an iPad or other medium-sized display anywhere near an open mic, the backlight power generator is perfectly capable of generating and radiating interference at around that frequency - in just the same way that the line oscillators in old-style TVs did. And people tend to take them into studios... Generally it doesn't become apparent until much later, often at the mastering stage, and it's virtually impossible to remove this invisibly (the reason is technical and boring, and relates to the way digital filters have to work).
Often, your best bet is to get somebody to make a recording of the track from the vinyl release using good equipment. They have to take a lot more care with clipping and peaks on this, or it simply won't track correctly on the player. If it still sounds crap after that, then somebody blew it completely at the mastering stage, and there's nothing that can be done except complaining like stink to the record label, and getting them to remix it properly. Personally I think you should do that anyway!

If you look at the spectral display of many film sound tracks you will see this 15khz line coming from the monitors playing back the film in the music studio.

Rather harder to avoid in my case - the performer was using the iPad as a score display, and reading from it.

If you rip it, you get an exact bit copy of what's on the CD - you won't have caused this at all.
Burning the 24-bit download is easy in Audition - there are links to a couple of blog posts that cover all you need in this FAQ:

In these days of loudness wars I doubt it would do much good, but if the mastered CD really sounds as bad as you say, I'd complain to to the record company or perhaps the band. i doubt one letter or email would change things but if the complaints start to arrive in the thousands, who knows.
Well, I can dream can't i?

Hi Bob
i spent about 80€ or more for the cd and the vinyl
and yes i'm very disappointed
what makes me very disappointed is that i have googled A Moon Shaped Pool bad recording , or clipped recording or noise recording , crackle and i found many users with a bad press cd
but many others has a good copy, that's very weird
i guess nobody will care complain my email
i will rent a project with external usb and i will rip the vinyl
thanks

Hi SteveG
i know how burn it ,but i will get a 16bit cd
i'm wondering if i can burn a dvd audio @ 24 bit
If you rip it, you get an exact bit copy of what's on the CD - you won't have caused this at all.
i know there are several cd with copy protection , even it's a right have 1 copy of the cd , i tought it was generated by the copy protection

Not with Audition - and quite frankly there's no point, as you will absolutely not be able to tell the difference. It's all been carefully researched, and the results published years ago. Nobody can do it!

The copy protection - what there is of it - doesn't affect the audio at all. I think that all rippers ignore it completely these days.

Perfect timing. I came up with a process in audition scientific filters a couple years ago. I need someone to try it and advise what they think. I became frustrated and use it to "reverse" the effects of the volume wars.
Convert the audio file to wav
Open audition and open the wav file
Reduce the volume to just under -6 db
open
Effects->Filters->Scientific Filters
Select the group delay button
Select Chebychev for Types
select Band Pass for mode
Master gain 0
set the following parameters:
Cutoff=4, High Cutoff=22050 for 44.1k audio, 24000 hz for 48k audio
Order=18.
transition bandwidth unchecked
pass ripple 0.00
press apply
then magic

I personally don't have anything to try this on. Could you post a short before and after example? With waveform shots?

As Steve says it won't matter what software you use to rip the CD the clipping and distortion will always be there since it is burnt into the CD audio unfortunately by the people who mastered/produced the CD version.
