João Carvalho

João began his mastering career in the mid-1990’s while producing records for many of Canada’s groundbreaking artists of the time. In the 90's, it became apparent there was a need for a fresh take on mastering records. With the help of a Red Focusrite equalizer and a cheap tube compressor at his then Umbrella Sound Studios, João set out to introduce “indie style” mastering to Canada. Fast forward to 2003: with a bravado-filled vision fuelled by many loyal friends and some very talented and technically minded colleagues, João Carvalho Mastering opened its doors.

By 2013, João had mastered 2000+ recordings: Rush, The Sheepdogs, FUN, Passenger, The Smashing Pumpkins, Ron Sexsmith, Sean Hook, Alt J, Sloan, The Tragically Hip, Death From Above, Lights, BADBADNOTGOOD, River Tiber, Walk Off the Earth, Hayden, Tanya Tagaq, Buffy St. Marie, Mobb Deep, Olivia Newton John, Blue Rodeo, Alexis on Fire, Protest the Hero, The Vienna Philharmonic Orchestra, Grand Analog, Stan Rogers, Charlotte Day Wilson, Chris Hadfield and Dead Tired to name a few.

In 2011, to further his passion for the ultimate in audio production, João partnered with three colleagues and opened the doors to Revolution Recording. This ambitious 3 studio complex now provides the ultimate recording experience for artists making music.

Today, João focuses on continuing to perfect the art of mastering audio, striving to ensure total sonic satisfaction to both himself and to others who choose to listen without compromise.

João lives in Toronto with his family and has a somewhat (un)healthy passion for cars and fine audio equipment.

Tim Branton

Tim R. Branton grew up next door to Gordon Lightfoot's drummer. His first drum kit, borrowed from his kind neighbour, soon replaced Tim's first instrument, a green plastic pail. Tim's early studies in electrical engineering evolved into a more creative degree in Radio and Television Arts from Ryerson University, specializing in advanced audio production.

After graduating, Tim managed Ryerson's School of Radio and Television Arts Audio Library, assisting radio and audio production classes by day, and cutting his teeth in Toronto's booming independent music scene of the early 90's by night. From 1995 to 2003, Tim was the co-owner of Inside Music's Greenpail Studios: a premiere production house and recording facility; with interests expanding into all aspects of the music industry; including development, promotion, marketing and management of up-and-coming acts.

In early 2003, Tim moved his freelance Mastering Engineering services from a small room at Greenpail Studios, over to Canada's first and only world-class Mastering facility, Joao Carvalho Mastering. Tim's technical expertise and "golden ears" have made him the go-to guy for independent mastering in Canada; serving clients from the Yukon to Newfoundland and overseas. Over the years, Tim's discography has expanded to include literally hundreds of recordings from all music genres and styles. Since 2006, Tim has been moonlighting as a Production Labour Supervisor for Snaphoek Staffing; applying his technical know-how to events such as The Juno Awards, The Much Music Video Awards, Cavalia, Cirque Du Soleil, Luminato, Nuit Blanche, among many others.
In his spare time, Tim can be found indulging his new-found passion for wine collecting and, naturally, consumption.

Charles Carvalho

A true "jack of all trades", Charles "Chuck" Carvalho really has had his hand in most aspects of music production throughout the past few years... and then some! Chuck started as an intern while JCM was under construction. If ever you get the chance to inspect the stunning woodwork staining and varnishing on the ceiling and walls of the mastering room, you will see some of his earliest masterpieces. Soon after the studio was constructed, Chuck interned alongside many talented engineers and producers, picking up techniques and tricks from some of the top names in the business; including his dad João. Soon afterward, solo mastering duties began and it was clear the boy-wonder had a knack for making great sounding audio. A streak of critically acclaimed artists soon found themselves working with Chuck: The Tragically Hip, Alexisonfire, Pilate, Gregory Hoskins, Danny Michel, The Toronto Symphony Orchestra. All at such a young age... and of course it wouldn't stop there. Chuck began working alongside audio design guru Dave Miller of Airfield Audio and hand wired and assembled the famed Airfield Liminators which he continues to do til this day. With this acquired electrical knowledge, Chuck dove head first "quite literally" into Revolution Recording's coveted Neve console, helping bring it back to its original glory before the opening of Revolution Recording studios in 2011. At this point, what does a young man have left to do? Wiring race cars perhaps? Getting in tight with the ChumpCar racing series, Charles now dabbles in auto racing already being a top qualifier in Formula 2000 race times. When will the boy stop!! So whether it's mastering records, recording bands, building studios, repairing a vital piece of gear or racing cars, it's quite possible that Chuck is your man. We said before, Chuck knows what to do, what not to do and, most importantly, how to get the it done right. Oh and don't worry, he vehemently wears hearing protection when in his race car.

Stephen Stepanic

Stephen Stepanic was totally hooked after cutting his first record at the age of sixteen on sixteen track analog. While earning an Honours Degree in psychology at The University of Western Ontario in 1993, he never stopped working with bands and recording.

Post university led to a degree earned at the Ontario Institute of Audio Recording Technology (OIART) in 1994, where, he finished at the top of his class. Stephen then landed a job at Digital Music Studios in 1995 working under MIke Jones where he gained valuable experience as a second engineer. Stephen moved on to the legendary Manta Eastern Sound studios in 1998, the exciting start of his mastering career. Here he worked with such artist as Beyonce (Desntiny's Child) and Billy Ray Cyrus.

Stephen continued immersing himself into the mastering sand box, and, decided the next logical step was a productive ten year stint working freelance. In 2010, Stephen had taken the head engineer position at Grayson Matthews Music + Sound which led to mastering work on sound tracks for Hockey Night in Canada and music for the feature film Art of the Steal (TIFF 2013), and countless commercial works. In 2014 the pull of freelance had returned. This is where Stephen is today, functioning as one of Toronto’s busiest freelance engineers, and, also continuing proudly as senior mastering engineer with joaocarvalhomastering.
