ATRAC or LPCM ?

Here are 5 flacs that Lucifer burns sent to me that were converted to WAV without error and zoomed in on 2 seconds. FA's and SA's analyzed with CEP in black and white. These are HI-MD minidisc masters.

Need opinions if these are LPCM mode mini disc recordings. I believe them to be LPCM and not ATRAC.

Thanks, could you please help us and send a MOD that is, so maybe this problem can be cleared up once and for all?
I like to be able to get back to uploading shows on here again asap.

Re: ATRAC or LPCM ?

I don't understand, why we're being ignored by the MODS.
I thought this was the place they wanted you to post stuff so they could analize it??

Re: ATRAC or LPCM ?

Hello.


your screens shots are of little use.

you may omit the frequency analysis, which has very little to do with determining whether audio has been through lossy data compression.


please post 2-3 second spans, in color, from Cool Edit Pro 2.x / Adobe Audition, so we can actually see something.

Re: ATRAC or LPCM ?

So this is the only program on the market that can tell us when a Minidisc recording made after 1/1/2008 is lossy or not??

Cool Edit Pro 2.x / Adobe Audition

This not a cheap program and i did not see a "free trial version" available.

Before i purchused the SONY Hi-MD MZ-M200 i researched it in 2009(i was already a member here)to make sure it was not ATRAC or lossy in the standard modes. The manual even clearly denotes this with out actually using the word "lossy".
What i really think happened is that the technology has changed in Minidisc recorders since your ban in 2008, and you just don't want to admit you've made a mistake.
Instead it seems you want me to jump thru "hoops" to prove otherwise.
I've submitted the same frequency analysis at two other sites and they pass the "lossy test" for their sites, but it is not good enough here??

Come on guys let's pull that ban until you can prove the oppisite or just admit that the technology changed and you were unaware.
We all make mistakes and no one will hold it against you.

I have no desire what's so ever to share "lossy" recordings and would gladly support the ban....if you can prove otherwise.


You even state in you other comment on the other thread that not all MD's have ATRAC compression after 1/1/2008.

Well, first off, Adobe did an "interesting" thing recently, and basically made it free to download a bunch of Adobe programs (Including the formerly expensive Audition). You can easily find a download link for it here:
http://www.adobe.com/downloads/cs2_downloads/index.html

Secondly, if you record Hi-MD's as LPCM files (.wav files) they are lossless and good to post. Any other "standard modes" it records in are lossy and banned, unless the show was recorded pre 01/01/2008.

You're being pretty ignorant of the fact that the users of this site have debated and (more or less) agreed that we will adhere to a higher standard of standardness, and that there are plenty of other sites to upload less than our standard of quality. If you KNOW you're recordings are LPCM then there's no need to test them, is there? I believe you can get 90 minutes on one Hi-MD large capacity minidiscs. If you're not using those dreadfully expensive Hi-MD discs to record on, then it won't be LPCM, it will be lossy, and not allowed...
