4X Latin Grammy winner and 5X nominated, Carlos Hernández  Carbonell, is a mastering engineer certificated by the prestigious Mastering Academy USA.  In the last years Carlos has mastered songs for artists like: Joaquín Sabina, Ismael Serrano, Rozalen,  Arnau Griso, El Chojin, Canteca de Macao, Estopa, Ana Mena, Xuxo Jones,Omar Montes, Isma Romero y Bely Basarte,Aitana, Clara Montes, Martin Zarzar, Xriz, Sofia Ellar, Andrés Garcia, Los limones, Eva Ruiz, Marta Botía, Nacho Campillo etc.. And has participated in recordings like “El Dorado”  Shakira´s álbum.

My goal is always reach the maximum potential of any mix, respecting it. In this digital era is very important to start  keeping  the quality of the recorded/mixed  material; sample rate conversion using the wrong software, or the misuse or omission of dither can cause the music to lose depth, clarity,  impact or naturalness in only one step. Is therefore very important to advise the customer on provide the “correct” files to start with. (…)

Maintaining or enhancing the dynamics of the mix is also very important to me. I always try to find the perfect balance between   “loudness” and  dynamics or vitality of each particular song. Trying to  enhance it´s exciting and emotional content. (…)

The final product must have no artifacts or clics, and translate whatever  the artist and producer pretended, in many systems as possible. (…)

I met Carlos on a Mastering Academy seminar in New York which I have
hosted together with Alan Silverman in 2014.
Subsequent Carlos started occasional supervised mastering sessions with
me to work through some mixing and mastering projects.
I saw Carlos evolving from a talented junior audio engineer to an
experienced senior engineer with a great sense and empathy for the music
he is working on.
As we have no hurry to push Mastering Academy participants to
examination Carlos took his time to get there with sometimes just one
supervised mastering a year.
However, in 2018 Carlos has finally passed the examination which is a
full mastering project to be done in 48 hours with a subsequent in-depth
Carlos passed with excellence! He did an outstanding job on that
mastering and I frankly couldn´t have done it any better.
I am happy and proud that I could see Carlos evolve into a world-class
engineer doing very skillful and musical decisions.
All the best for your future career, Carlos!
