guillaume chalaron mastering


born in France from a musical background between jazz and classic

After studying psychology and music, I install myself as a guitar teacher mid 90ies and became interested in sound/tone production of instruments
I developed last decade solutions to extend emotion of digital music
positive feedback from worldknown brands at High End Audio Show in L.A, France, Poland, Germany defined this 'audiomastersystem' as a clean and organic sound expected by many experienced audiophiles



is a company and trademark registered in 2017

its advanced mastering chains return not only digital to quality of highly mastered vinyls records quality but also revisits actual mastering with more naturalness in sound

that hybrid sound architecture is now approved by music producers, mastering engineers and international artists, digital can meet analog






Great mastered vinyl records and digital files

have revealed interesting differences

at several international audio shows

on advanced playback systems


I did 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






INPUT: Audio⩾16bit/44kHz


Back To Analog Roots


We can return 'old' CD masters to quite the 1st original

vinyl pressing of the analog masters,

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


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

Improved dynamic range perception

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 start from original stereo mix

Results are very positive after one year of research analyzing specially

recent works from Bernie Grundman, Tom Coyne, Tim Young and others










Points affecting the musical rendering



Extended Dynamics

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

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 achievements

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



Maximum Transient Fluidity

RM can improve transients and signal liquidity

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 orchestra
