I don't just "process" audio — I cook it.

The industry is full of fast-food engineers. They throw a couple of presets on your tracks, microwave the mix, and call it a day. That's not what happens here.

At Caldero Sound, your raw files are treated like premium ingredients in a high-end kitchen. I strip the fat from the guitars. I boil down the low-end until it punches you in the chest. I balance every frequency with the ruthless precision of a master chef.

From the aggressive breakdown of a kick drum to the soaring cry of a lead vocal — nothing leaves my studio until the flavor is absolute perfection.

Raw energy is the ingredient. Brutal precision is the dish.

Every stem, every recording is a raw ingredient I carefully listen to before anything starts.

Editing = Preparation

Timing correction, tuning, cleanup — the meticulous prep that makes or breaks the final sound.

Mixing = Cooking

Where the flavours come alive. EQ, compression, saturation, and reverb blended into a cohesive sonic dish.

Mastering = Plating

The final presentation — loudness, consistency, and impact polished to perfection before it reaches the world.

The Recent Serve

THE RECENT SERVE

Every dish you hear was cooked from scratch — remotely, from Cambridge, UK — for artists across Spain, the US, and beyond.

Rock. Metal. Metalcore. Death metal. Alternative. Artists like Headon, Debler Eternia, Winnower, Watch Me Die Inside, and Daeria. The sonic detail is in the listening — pop the lid.

Voices From The Scene

VOICES FROM THE SCENE

Trusted by metal alchemists

We always aim to sound cutting-edge, with the most powerful and modern sound possible, and that's down to our producer Javi Perera. I met him when I was just starting out on YouTube, and to this day, he's still the producer of all our albums.

Andy Martínez (Headon)

Javi works his magic in the mixing and mastering stages. He took our sound and elevated it eightyfold. We asked for recommendations and were told, "He's the best." From the very first meeting, there was an incredible rapport, and we decided to entrust him with the entire album. He became one more member of the team.

Ruben Kelsen (Debler Eternia)

Javi has been absolutely irreplaceable. A mix/mastering wizard. He's made pretty much everything come to life.

FREQUENTLY ASKED QUESTIONS

I don't just specialise in genres; I specialise in sonic impact. My home is in rock, metal, and alternative music — genres that demand visceral weight, power, and depth. If you are looking for an aggressive, world-class sound and refuse to settle for an “amateur” or plastic mix, that is exactly my territory.

I don't waste time bouncing emails back and forth with confusing notes. I use high-resolution, real-time audio streaming via Muse Sessions. You sit in your listening environment, and you hear exactly what I hear in my studio in real-time. It's an immersive, collaborative experience where we make critical aesthetic decisions together, protecting the emotional core of your music.

My critical listening environment is based in Cambridge, UK. However, my entire Sonic Production workflow is meticulously designed for global remote collaboration, allowing me to work one-on-one with artists anywhere in the world without losing an ounce of impact or communication.

READY TO START?

Not every dish is worth the effort. Not every project is worth the fire.

Every recipe at Caldero Sound is built from scratch — no automated quotes, no preset solutions. If your music is ready to be cooked at the highest level of intentionality, tell me about it. I only take on projects where my involvement will change something essential about the sound.
