Mastering Services
Mastering is the last step in the production of a record, that crucial moment just before your music gets released and sent out into the real world. Making use of my experienced ears, a fantastic sounding room, outstanding speakers and an array of hi end analog and digital tools I will add clarity, definition and punch to your music and make sure it translates perfectly in all systems and environments.





About Me
André Castro
Mastering Engineer
I have been working with digital and analog audio for over 15 years and mastering professionally for the last 5.
In 2015 I was tutored and trained by the world-class Mastering Engineer Friedemann Tischmeyer and got hooked. Since then I have been blessed to be able to provide mastering services to incredibly talented artists from all around the world.
My commitment is to work with you towards delivering the best possible presentation of your music. Your music will be mastered in a way that is respectful to both the artistic vision and the mixers intent. I am not interested in doing a rushed and careless job. I take my time, team up and work with you relentlessly towards the betterment of your music.

Studio
I will be mastering your music working out of an acoustically treated room designed by renowned Acoustical Engineer John H. Brandt, coupled with outstanding reference monitoring system by Bowers & Wilkins. The studio provides a revealing and neutral experience, allowing me to listen deep into the fine details of your music. I use a blend of hi-end analog and digital processors that lets me pick and choose what's better suited for each song.

André has mastered our latest Album and the result is amazing. It didn't took him long to understand our ideas and apply them to the final work. The perfect balance for the style we play. Couldn't be happier.
It rests our mind to know André exists.

André mastered my most recent album and I couldn't be happier with the work he did! Gave it a really big sound while maintaining the dynamic range of the music. I definitely plan on working with him again, and I would highly recommend him to anyone.
