DID CONCLUDE digital can meet analog







Great mastered vinyl records and digital files have revealed interesting differences

at several international audio shows on advanced playback systems

Aspects of integrety of sound were lost

I did work on a merging technique and a complex algorithm to restore the original sound

Listeners achieve a better musical experience

Transpose the process to current digital recordings and new sonic abilities impact again



Back To Analog Root



RM returns 'old' CD masters from last century close to the original

vinyl pressing of the analog masters,

Working on how to match 50 referent records including

45rpm, half-speed mastered vinyls, direct transfer from analog tape

Approved by Bernie Grundman,Jeremy Kipnis,



Towards Master Quality



Revisiting sound due to proper limitations of some vinyls

and digital formats is another goal for a more satisfying experience


Simply hear hidden aspects of music with more emotion

Some quality heard on analog master tape recordings

are generated by the mastering chain



Mastering the Mix



2 new mastering chains adapted for original stereo mix

Results are positive after one year exploring some

works from Bernie Grundman, Tom Coyne, Tim Young,...






Our mastering chains deliver a huge 32 bit DXD matrix master

To avoid losing sound quality when downsampling/converting to lower sampling rate and bit,

A direct D/A/D transfert to the final audio format is our new offer

It even brings more naturalness and soundfield qualities







Extended Dynamics

More Realistic, like 45s RPM records, RM can enhance the dynamic range,

reversing the effects of usual drastic compressions


Flexible Soundstage

A full sound is able to radiate beyond the area of the speakers

without removing the impact and focus of the center

RM can fill/empty the room and get you at an orchestral performance


Advanced Stereo Imaging

Left, center and right locations are wider and lighter

to generate more distinctive informations in the whole room

enabling a continuous and realistic spatial distribution


Sound Layers with 3D Transparency

Three dimensional enveloping sound, outstanding depth and clarity

are the most complex achievements

Digital can translate new acoustic spaces, the 'analog spirit'


Maximum Transient Fluidity

RM can improve transients and signal fluidity

through digital conversions up to DSD2048

and a technique to reduce the digital sounding aspects


'Intelligent' Balance

Human perception of frequencies/level changes is not linear

Spectrum balance and sound dynamic were elaborated

after psycho acoustic test and comparisons to live performances
