Overview

International Sound Studio (International Soundstudio SA) is a Spanish sound studio headquartered in the Poblenou district of Barcelona, near the Olympic Village. The company describes itself as a studio for sound, dubbing and advertising, and its facilities are located at Pujades 57 and Pamplona 72-74 in the 08005 Barcelona postal area. Its core business is audio post-production: dubbing, subtitling and sound mixing across all major formats, including Dolby Atmos and Dolby Digital. The studio states that it has accumulated more than 10,000 hours of dubbing, subtitling and sound-mixing work, which it presents as the foundation of its experience and of its professional team. The firm operates as a Sociedad Anónima under Spanish law, with tax identification number CIF A62035761 and a registered address at Pamplona 72, 08005 Barcelona. Its public communications emphasise quality and service as the guarantee of its future, and it markets itself to clients who need Spanish-language and multi-language audio production, advertising voice work and audiovisual localisation. Contact details published on its website include the telephone number +34 933 208 400 and the email address soundstudio@soundstudio.es. International Sound Studio is a business-to-business service provider rather than a consumer-facing brand. Its clients are typically production companies, broadcasters, advertising agencies and distributors that require dubbing, subtitling or final mixing. The studio's location in central Barcelona places it within one of Spain's main audiovisual production clusters, close to the Villa Olímpica and the Bogatell metro station, and accessible from the AP7 motorway via the Ronda Litoral and the Port Olímpic exit. Because the company is privately held and does not publish detailed financial or corporate history on its website, information about its founding year, founders and ownership beyond the SA structure is limited. What is clear from its own materials is its positioning as an experienced, format-agnostic audio post-production house in Barcelona, equipped for cinema-grade formats such as Dolby Atmos as well as standard broadcast and advertising deliverables.
