After 15 years as a staff engineer at San Francisco’s legendary One Union Recording Studios facility and then two and a half years partnerning at advertising audio house Handsome Sound, Eben Carr is taking all of the experience of producing, engineering, and mixing audio for advertising content, as well as a deep understanding of the business of that sector, and rolling it into Tone11, Inc., his new production and mixing facility in the city’s Ice House Alley neighborhood. Housed near Levi’s Plaza, in a building that is part of one of the largest and oldest masonry constructions in the Bay Area, Tone11 boasts a sound that is as modern as it gets, utilizing a Genelec monitoring system that will help keep San Francisco a hub for advertising audio.
