Your music deserves to sound like a professional release.
Remote mixing and mastering services for artists in the United States, Europe and Latin America. Every project is handled personally by engineer Roberto Lucaro in his own studio.
Does your track still not sound the way you imagined?
These are the issues that come up most often when a song is not ready to be released. All of them are solved with a proper mix and master.
Buried vocals
The performance is there, but the vocal never reaches the listener.
Muddy low end
Kick and bass fight for the same space and lose their punch.
No impact
The track plays, but it doesn't hold attention in the first seconds.
Undefined mix
Elements blur together and nothing has its own place.
Inconsistent loudness
Loud on one system, gone on another, with no translation.
Two services, one listening standard.
Analog mixing
Depth, movement and decisions you can feel.
Mixing combines the control of the digital workflow with the response of the analog console to build clarity, impact and identity — without turning your music into a formula.
Mastering
The final stage should translate, not just get louder.
Mastering finishes the track with consistency and prepares delivery for Spotify, Apple Music, radio and every playback system.

The engineer behind your music.
Roberto Lucaro handles every mix and every master at Estúdio JRM. He listens to your references, decides the character of the sound and signs off on the delivery — from the first audio file to the final master.
The idea is simple: combine the physical response of an analog console with the precision of a digital workflow to deliver tracks that compete on streaming.
Before we talk.
How much does mixing or mastering cost?
Every project is quoted individually. The price depends on the number of tracks, the state of the files and the scope. Send the details over WhatsApp and Roberto replies with a custom quote.
How do I send my files?
After the first conversation you get guidance on how to organise stems and send them via WeTransfer, Google Drive or Dropbox. WAV, MP3, stems and Pro Tools or Logic sessions are all accepted.
How long does it take?
Turnaround depends on the scope and is agreed before we start. Single songs are usually ready within a few days; full albums need more planning.
Can I send vocals only?
Yes. Vocal-only projects for mastering or specific treatment are common. Message Roberto to align on what makes sense for your track.
How many revisions are included?
Up to two rounds of revisions are part of the standard scope. Extra adjustments are agreed case by case.
Do you work with artists outside Brazil?
Yes. We work with artists across Europe, the United States and Latin America. The whole process is remote — WhatsApp conversation and file transfer by link.
