    Carlos was very hospitable in attending to my mastering needs. Prompt in delivery and willing to create a series of masters (rather than just one) for me to compare before finalising, he also lent advice on different audio formats and modern modes of mastering. Responsive, prompt and highly detailed across mastering.

Interview with Carlos Freitas - Classic Master

What's the biggest misconception about what you do?
The mistake are mix and master simultaneously, something increasingly common nowadays, making the production process miss an important component, which is performed by an expert in mastering .
What do you bring to a song?
Emotion, always! My goal is always understand and enhance the emotion contained in each song during the mastering process , detecting elements of music that can help the artist to express and enhance the emotion of its art, in a way , that their fans can capture that feeling to listen to their music .
What's your typical work process?
I start my mastering process listening to the album, preferably with the songs in the final sequence . Then, I talk to the producer via skype about his expectations for mastering, references and other needs, taking notes for details for each song on a worksheet. After the talk , I separate the songs by style to be mastered in blocks. I test different set ups among my equipment until find the most suitable and move on the process, always comparing the songs to each other , to get a good balance between them. At the end, I do final editions , balance and final adjustments and then, I listen the final master before sending the project to the client for approval.
What questions do customers most commonly ask you? What's your answer?
What do you think about my mix? I usually say that when a mix comes to my studio to be mastered , it is ready and approved by artist and producer and I focus my work on the emotional aspects and technical for distribution and as a matter of ethics, I do not make judgments.
What questions do you ask prospective clients?
What message does he want to tell his listener through his music and what I can do in my mastering work to help him to achieve this goal ?
What advice do you have for a customer looking to hire a provider like you?
Tell me all possible information about your work. This will help me to understand your expectations and reach the best result of mastering your project.
How would you describe your style?
I like to work always together with the mixing engineer and the producer of the album. Teamwork is essential to achieve the best result always.
Which artist would you like to work with and why?
I would like to work with Paul McCartney, mastering one of his album, for all that he represents to the world music .
Tell us about a project you worked on you are especially proud of and why. What was your role?
I like so much my work on Brazilian Singer Ed Motta's last album "AOR". Ed is purist and rigorous about their work and pushed me hard until we get exactly the result he wanted. It was hard , but we did it! This album was latin grammy nominated!
Analog or digital and why?
I think that the process of equalizing or compressing are personal skills and equipment are tools, so it does not matter if your tools are analog or digital, it cares if you are skilled to use them.
What's your 'promise' to your clients?
Do my best during mastering process working on his music in order to help them to express and enhance the emotion of his art for their fans.
If you were on a desert island and could take just 5 pieces of gear, what would they be?
B&W Monitors, Maselec MEA-1 EQ, Maselec MLA-1 Comp, Maselec MTC-1 and Manley Varimu Compressor.
What was your career path? How long have you been doing this?
I start working with audio in 1983 as second engineer and in 1986, recording and mixing engineer. In 1992, I began my mastering journey until nowadays.
Can you share one music production tip?
Believe in what you are listening!
What type of music do you usually work on?
Brazilian and Latin Music.
What's your strongest skill?
Focus ! During the mastering process , I keep my focus on process strongly always.
Tell us about your studio setup.
Our mastering set up consists of a mix of tubed and Solid State equalizers and compressors from Maselec and Manley. They are all connected to the Maselec MTC-1 mastering transfer console, which in addition to controlling the monitor, allows me to quickly change and choose the type of equipment to be used during mastering process considering the song's style. The digital converters are the Lavry Golds , which in my opinion are the most transparent converter available and in the digital domain, I use the Universal Audio, Sonnox and PSP digital limiters, Isotope RX4 for sound repair and soundBlade for final edit.
What other musicians or music production professionals inspire you?
Bernie Grundman and Doug Sax always inspired me as Mastering Engineers.
Describe the most common type of work you do for your clients.
CD and DVD 2.0 and 5.1 mastering continues to be our main job here in Classic Master, however, mastering projects for online distribution only such as Spotify and iTunes MFiT and mastering for Vinil are growing faster and we are well prepared for that.
What are you working on at the moment?
We are working on CD and MFiT projects.
What do you like most about your job?
The emotional aspect care during mastering process.
