...iTunes (Music Store) = AAC / MP4 (.m4a) ABR 256iTunes (iTunes Match) = AAC / MP4 (.m4a) VBR 256...
They do vary depending on what was provided to them. So far, these are the ones I have come across:-V 0 Lame 3.98 joint-stereo-V 0 Lame 3.97 joint-stereo256kbps CBR Lame 3.96 stereo256kbps CBR Lame 3.91 stereo256kbps CBR FhG stereoI downloaded a new song a couple of weeks ago and it was 256kbps CBR FhG stereo as well so I don't think Amazon has tried to do anything to even out their offerings. That is one of the reasons why I stopped buying from them. Although the chances of me actually ABXing anything are slim to none, I don't like the idea of not knowing what I will get and I like my lossy library to be uniform.
So, do you think they do the actual rip? Or do they all get it from the cd provider and state a minimum quality standard and the folks that provide the CDs to the stores also make the mp3s for distribution?
Amazon = MP3 (LAME) (.mp3) VBR V0
Why is so difficult for these company say to us what they use and how the make their mp3! Really, so frustrating :-(
Amazon does indeed bury that page, but it does exist:http://www.amazon.com/gp/help/customer/dis...odeId=200389400
For my own ripping and encoding, I use EAC and let it launch RazorLame. My current (EAC) settings for RazorLame are:path: G:\Program Files\Exact Audio Copy\lame.3.97.b2.exeAdditional command-line options: -V2 --vbr-newBit rate: 224 kBit/s[X] Delete WAV after compression[ ] Use CRC check[X] Add ID 3 tag[X] Check for external programs return code(*) High quality( ) Low qualityLooking at the properties of an mp3 in foobar2000, it shows encoding settings as:lame.3.97.b2.exe -h -b 224-V2 --vbr-newDoes that seem reasonable? How does that compare to what amazon and itunes are releasing?
and.... big disappointment:
how can it be that Amazon used such a lower quality setting?

I just wanted to say that you compare AAC (M4A file from iTunes) and MP3 (from Amazon). And yes, AAC spectrograms usually look better.
