GUTS: Mastering wih John Dent

"Freedom", the last album of GUTS, has been masterised at Loud Mastering, in Taunton, UK.

Guts releases some sacred moments plus a special masterclass by one of the best, or even THE best, mastering engineer: John Dent.
Sir Dent has worked on lots historical vinyl albums such as most of Bob Marley's. If you've ever heard about music, you definitely must know John Dent's work.

Enjoy, music lovers !

WHY IS ANALOG BETTER THAN DIGITAL ? AN ALTERNATIVE EXPLANATION...

Sampling consists into the transformation of an analogue signal (an uninterrupted sound, infinitely precise) into a digital signal ( a continuation of discreet points), by capturing samples (snapshots) at regular intervals.

The frequency in which samples are captured is called sampling frequency, and is expressed in Hz.

For instance, an audio CD contains musical data sampled at 44,1 kHz (44 100 samples per second). On the same tip, an MP3 at 192 Kbits /s corresponds to CD quality divided by 7.

Normally, our ears can perceive frequencies going from20 Hz to 20 kHz. Actually, we mostly hear correctly frequencies going from 2kHz to 5 kHz. In fact, less than 5dB are needed to hear frequencies located in this band, while 20dB are needed at least to hear frequencies located underneath 100Hz or above 10kH.

A CD can only be precise up to 4 KHz, over which the sampling is not accurate , therefore highs are of mediocre quality.

In MP3s, all frequencies above 11kHz are cancelled. Ther highs are of very bad quality.

On vinyl records, frequencies go up to 25 KHZ and, moreover, they are not sampled ( as a continuation of discreet points) , they are pure ( an uninterrupted sound, infinitely precise).

In conclusion, without us knowing it and without even noticing, day by day our field of frequency is considerably reducing.


POURQUOI LA QUALITÉ D'UN VINYLE EST-ELLE MEILLEURE QUE CELLE D'UN CD ? (L'ECHANTILLONAGE NUMÉRIQUE)

L'échantillonnage consiste à transformer un signal analogique (son continu d'une précision infinie) en signal numérique (suite de points discrets), en capturant des valeurs à intervalle de temps régulier .

La fréquence à laquelle les valeurs sont capturées est la fréquence d'échantillonnage exprimée en Hz. Par exemple, un CD audio contient des données musicales échantillonnées à 44,1 kHz (44 100 échantillons par seconde).Un MP3 en 192 Kbits/s par exemple , c'est la qualité CD divisé par 7 .

Normalement, notre oreille entend les fréquences situées dans la gamme [20 Hz - 20 kHz] , Pour aller plus loin, on peut dire que l'on entend surtout correctement les fréquences situées dans la gamme [2 kHz - 5 kHz]

En effet, moins de 5dB de niveau sonore suffit pour entendre les fréquences situées dans cette bande alors qu'il faut plus de 20dB pour entendre les fréquences situées en dessous de 100Hz ou au dessus de 10kHZ

Pour le CD , Il n'est précis que jusqu'à 4 KHz , au-delà desquels l'échantillonage n'est plus précis. Les aigus sont donc de moyenne qualité.

Pour le MP3 , toutes les fréquences au dessus de 11kHz sont supprimées. les aigus sont de trés mauvaise qualité .

Pour le vinyl , les fréquences vont jusqu'à 25 KHz et surtout , elles ne sont pas échantillonnés (suite de points discrets) , elles sont pures (son continu d'une précision infinie)

Conclusion, sans le savoir et sans s'en rendre compte au quotidien , notre champ de fréquence est en train de se réduire considérablement.

I facepalmed so hard, it's not even funny. I actually said "Holy shit" as I was watching.

This guy clearly has something against digital. And of course, he has so much old analog gear, so it's his business to delude himself and others into believing that his product is markedly superior.

Look up "Audio Myths Workshop" here on YouTube, as there are lots of vital informational nuggets in there. And, for Christ's sake, look up the Nyquist-Shannon Sampling Theorem.

Ok actually this maybe a bit radical, like I think there's some good in analog AND digital. Of course Digital is more accurate than that, but also still DON'T SOUD AT ALL LIKE ANALOG, especially High END analog gear (like those Manley and Crane song gear you can see on this video). But he is as wrong as saying we can only hear from 20 hz to 20 khz. It's not about physics but about tools qualities, I can assure you that doing Mastering myself as a professionnal :)

Oh my god. This dude does not know anything abut digital sound. He is spreading missinformation in this video. It looks like like he's making up his own physics to accommodate a personal bias for analog gear(which is very often thing with these so called mastering engineers). I woulkd like to make blind test with him :)

[elpatriotaLX]

LOL gotta love the spreading of miss information on this video.

I had the pleasure of having a few of my early singles mastered by John, he did a superb job and has a great ear. True gentleman. Interesting that his room layout has changed quite a bit since I was there, large main monitors now horizontal too.

@mikethamike Essentially though the point John was trying to get across was correct in terms of accurately representing the true shape of the waveform at higher frequencies. The question is more whether that accuracy is important, if you break sounds down to their sine wave fundamental and harmonics, are those upper harmonics still needed when the human hearing won't go beyond that anyways, which is a whole other subject in itself.

Nyquist theory.

[Sebombadil]

lol... funny joke !

[ERICMEDINAGARCIA]

henri, eres un fiera. No tengo palabras. Larga vida al vinilo, larga vida a lo analógico.

PURA VIDA.

every day and every night.
