O trabalho do Carlos sempre surpreende, pois, conhecendo-o, a gente já espera perfeição - mas, na hora do resultado, sempre vem um algo a mais que ele, com sua sensibilidade e emoção, consegue ainda extrair ou valorizar do som, arredondando, agregando, tornando maior. Mestre total da arte, parceiro indispensável! Respeito absoluto!

O profissionalismo, e o respeito com a música, mixados e masterizados em puras frequências de bom humor e inteligência, sem dúvida definem o trabalho incrível e apurado desse grande amigo e mestre, Carlos Freitas!
Hace unos años, cuando estaba trabajando en mi primer EP, escuché un gran disco de Julián Ávila, guitarrista colombiano, masterizado por Carlos. Decidí masterizar con él y desde entonces todo lo que hago pasa por sus procesos. Un trabajo, limpio, garantizado y lleno de buena energía.
Since 1997, I've mastered over 60 projects (CDs and DVDs) with Carlos. In my point of view, Carlos has the most important qualities a mastering engineer could have, flexibility, experience and feeling to understand the aesthetic particularities of each project. So, he is always working to reach the sound result that each album needs. Thank you!
I have mastered many albums with the great mastering engineer Carlos Freitas at Classic Master in São Paulo.
