Great mastered vinyl records and digital files have revealed interesting differences

at several international audio shows on advanced playback systems:

aspects of sound integrity were lost on digital

I developped a merging technique and a complex algorithm to match

the original master analog recording sound and recently also work to master stereo mix

Adapt the main process to current unmastered mix with adjusted settings

provides new sonic abilities impact

Positive A/B tests at Audio Show in L.A, France, Poland, Germany, Budapest, China and from producers, international artists, mastering engineers reveal listeners achieve a much better musical experience than usually 

RootMaster-goals

                         1 Bring digital masters quality of great mastered vinyl records

                         2 Revisit actual mastering with more naturalness in sound

                         3 Master stereo mix with new compression, EQ, center focus

MASTERING CHAIN rm Ult/ExT BACK TO ANALOG ROOT

2017-2018

It returns 'old' CD masters close to the original vinyl pressing of the analog masters,

after working on how to approximate 50 referent vinyl records including

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

Approved by Bernie Grundman in June 2018

MASTERING CHAIN RM32 TOWARDS MASTER QUALITY

2019

Revisiting sound due to proper limitations of some vinyls and digital format is the second goal 

Mastering chain ℝM³² surpasses previous ℝM. Hear hidden aspects of music with more emotion

Some quality heard on analog master tape are now generated by ℝM³²

Approved by Jeremy Kipnis, Tim Paravicini

Stream MASTERING CHAIN ℝM³²

MASTERING CHAIN RM48 FOCUS ON UNMASTERED MIX

2021-2022

Mastering chain ℝM⁴⁸ with settings adapted for unmastered stereo mix

got positive results after two year exploring some works of

Bernie Grundman, Tom Coyne, Tim Young, Chris Graham, John Davis

With normal settings, ℝM⁴⁸ is surpassing ℝM³² anyway

Stream UNMASTERED MIX

mastering chain RM48 STABILIZED SOUNDFIELD

May2023

Most achieved digital chain only by computing

More accurate ultrasonic response and equalizers 

Better balance and more details

Stream/Download MASTERING CHAIN ℝM⁴⁸

WITH direct d/a/d analog transfert

Aug2023

Our mastering chain delivers a 32 bit DXD matrix from a full digital processing

Not to lose sound quality when downconverting sampling rate and bit depth,

our direct final D/A/D transfert of that matrix keeps details, adds more naturalness and 3D soundstage

RootMaster-chain

Extended Dynamics

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

lessening 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 leads you at an orchestral performance

Advanced Stereo Imaging

Left, center and right locations are wider and lighter

to generate more distinctive informations in the space

enabling a continuous and realistic sound distribution

3D Transparency Sound Layers

Three dimensional enveloping sound, extended depth and clarity

are the most complex achievements

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

Maximum Transient Fluidity

RM improves 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
