Upsetting Fact

 

Half-speed mastered vinyl records and digital files

have been analyzed for 7 years

They musically don't compare

 

 

Philosophy

 

Advanced digital playback and equipments don't solve enough all problems

Let's face the truth; it is high time to focus on the digital data itself

and find out a global mastering approach and result

 

I developed a merging technique in audio processing dedicated to

- shiftback 'missing and hidden' informations

- remove the remaining digital 'fingerprint'

 

Over 50 referent records including 45rpm and half-speed mastered vinyls

were used to verify the processing until they musically compare

STEP 1

Back to the Roots

 

I: 16bit/44kHz or better

130 operations by computing with audio software

O: RM (PCM and DSD)

 

First improvements are based on results showing that RM

returns digital track to a significant copy of

an original analog recording of the musical event

 

 

STEP 2

Towards Higher Quality

 

The ultimate goal for listeners is achieved beyond the musical limitations of vinyls

(hidden detail under noise, surface noise, 'monoized' bass, end side compromises...)

After long research, second improvements can achieve a cutting edge musical experience,

relying on 6 key components as shown on the drawing below

 

RM is a serious expected digital audio alternative

since numerous comparisons at high-end audio shows

Widescreen Dynamics

Far more 'realism', p to f will become pp to ff

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

dramatically reversing the effects of compression

 

 

Flexible Soundstage

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

But also subtle details return vivid (and not boosted)

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

 

 

Advanced Stereo Imaging

Left, middle and right locations are redefined

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 meet the 'analog spirit'

 

 

Maximum Transient Fluidity

RM can approach the analog's signal liquidity

through complex digital conversions up to DSD2048

and with 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 tests up to 100kHz, master tape and live concerts
