A Single-Source Solution A New Sound Architecture
 A Single-Source Solution A New Sound Architecture  


Guillaume Chalaron




I was born in 1969 in France from a musical background between jazz and classical music
After studying psychology and classical guitar, I install myself as a guitar teacher late 90ies and became interested in sound/tone production of instruments
I developed a decade later 3 solutions to extend emotion to digital music
From 2015, positive feedback from worldknown brands at High End Audio Show in L.A, France, Poland, Germany defined the 'audiomastersystem' as a clean and organic sound expected by many experienced audiophiles

After long comparisons to original analog masters, high end vinyls, a digital algorithm by computing became Rootmastersound, a new born company and trademark registered in 2017

This advanced mastering process returns not only digital to vinyl masters quality but also revisits actual mastering affected by the loudness war with more naturalness in sound

Nowadays, RM from Rootmastersound has been approved by music producers, mastering engineers such as Bernie Grundman and international artists




Difference and Choice


Great mastered vinyl records and digital files

have revealed interesting differences

at several international audio shows

on advanced playback systems


I chose to focus and work on weak aspects of sound to

make listeners achieve a better musical experience

Transpose the process to current digital recordings

and new sonic abilities do appear again




We developed a merging technique, a complex algorithm

to enhance the musical impact of digital track






I: Audio⩾16bit/44kHz



Back To Analog Roots


We can return 'old' CD mastered track to almost the 1st original

vinyl pressing of the analog recordings,

thanks to 50 referent records including

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

Now hear better music quality from last century!




Towards Master Quality

Q2 2020


Extended range beyond proper limitations of vinyls and digital contents

is another goal for a more satisfying experience


Simply hear hidden aspects of music with more emotion

Improved dynamic range

Some quality heard on analog master tape recordings

can be generated by this mastering chain




Mastering From The Mix

Q1 2021



Our mastering chain is now adapted to work from stereo mix

This is a big new challenge

Third setting achieved after 8 months of research comparing to recent results

produced by Bernie Grundman, Tom Coyne and Tim Young from the mixes



O: RM⁴⁸ (PCM and DSD)






Hybrid Sound Architecture

Digital can meet Analog







Options affecting the musical rendering



Extended Dynamics

Much more realistic, p to f  becomes pp to ff

Like 45s RPM records, RM can enhance the dynamic range,

drastically reversing the effects of compression



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 achievement

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



Maximum Transient Fluidity

RM can improve transients and signal liquidity

with a complex 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 orchestra
