Can you play that from Memory?

Note on Build 7:

From the company that originated RUR and "Memory Playback"
five years ago, comes a more powerful extractor, by far the most powerful in
the industry. Unlike all freeware and other memory players (as of January,
2009)it uses
no caching, and uses no error correction bits and no
non-sequential memory EVER.

Read the Technical Guides for details.
Build-7 boasts an incredible 150X rereading.
The most powerful, error code free CD extraction player
in the world.

The Memory Player/RUR Build 7 - January 2009
"RUR" (Read Until Right)
and The Memory Player

What's Wrong With Conventional CD Players?
Music is fluid, seamless, natural.  Over two decades have passed since the introduction of CDs, and we still, for
the most part, prefer old vinyl reproductions to even state-of-the-art digital playback.  There are powerful reasons
for this, but in essence, it can be reduced to a single tenet:  Virtually ALL complaints against digital sound can be
reduced to byproducts of the dissection of music into fragments, and an attempt to reassemble them perfectly.
dissection of a continuous music stream into "quanta", and reassembly attempts, always create TIME errors
and play bits
at the incorrect moments in time.  The vast complexity of The Memory Player's technology
focuses removing ONLY original music bits, placing them as a whole on electronic memory and playing them as
a bit stream - a near replica of the master stamped on the CD.

The most common neophyte's critique of the philosophy of "the
science of Memory Playback" is the "...all CD players
(or computers) play from memory, as they cache portions to a
small memory in CD players or CD ROMS" (usually 8 MB).  
Or, there is confusion between hard drives and "true" memory.  
Caching portions to small memory banks only creates further
dissection of the digital music.  Each time you dissect the music
signal, you must reconstruct it.  Since each reconstruction is
never perfect, you create more JITTER and more bits are played out of time.

Rereading vs. Error Correction Codes
A variety of codes are on the CD to reconstruct data that failed to be read; those codes are ECC, Parity Bits and
several others.  While they do reconstruct 100% of the lost data, the problem remains that plagues ALL error
correction codes:  TIME.  All error correction codes are created within an "acceptable time error" of about 25
microseconds that you're not supposed to be able to hear.  (Read in depth the analysis of why this occurs on our
website under the "Technical Guide" at

You will inevitably read somewhere that Reed-Solomon coding "perfectly and instantly" corrects all misread
data.  This would be true IF the code used for Music CDs was as strong as the code used for Program CDs.  It is
not.  The code used for Music CDs does not have the resolution to place a reconstructed bit in a timely fashion.
These "acceptable" errors of time manifest themselves as artificial notes and confusing harmonics created by
playing these bits at the wrong time.

Read Until Right (RUR) Erases Jitter
The Memory Player eschews all error correction,
because all error correction creates jitter and bits that
are randomly played within the time period of each
sample (44.1khz).  Instead, The Memory Player plays
a CD by extracting the data from the CD to pure,
non-mechanical memory, rereading it until almost all
information is captured.  Then, it plays the music from
this virtually error-free source - pure non-mechanical
memory.  This low a level of jitter and bits played as
they appear on the master presents a purity that is
impossible in mechanical CD playback systems.

Rereading Instead of Recreation
Music is stored on CDs in "blocks".  Most lost data and jitter occur when the beginning or ending of a block is
inaccurately read by the laser.  If a bit fails to be read, RUR ™ rereads it, and if it still fails, RUR will change the
position of where to start reading, where to terminate reading, and even overlap multiple blocks in order to
'capture' the missed bit!

And, RUR works in real time.  That is because it can deposit properly read CD information on the electronic
Memory; and, it can return to reread the CD still further, up to150 times, while the music is being played!

“Our first impressions of hearing
The Memory Player were the equivalent of a UFO
landing on my front lawn! This baby sounds better,
rather more musically correct and thus authentic of
music, than anything I’ve had digital thus far...
...and, I bought one.”

Clement Perry, Publisher - The Stereo Times

"During my initial listening experience, it reminded me of the very best of analog with
tube electronics!!!  Absolutely zero digital artifacts, and when compared to another
Basically, no contest; not even close by any standards.”
