Canvas, which will be headed by GCap's group creative director, David Couch, is the result of a merger between GCap's design, Sonics and audio-visual departments.
It has been designed to offer integrated solutions that work on radio, as well as off-air, online and across new technology. The Canvas team will be made up of writers, producers, art directors, designers, web developers and film-makers.
The launch will build on the work handled by the Sonics department, which was launched four years ago to help advertisers develop radio advertising alongside the use of sound in other media.
GCap hopes the launch will help it to further its relationships with both marketers and agencies. Couch said: "A few years ago we were pushing the envelope with clients, while explaining the psychology of sound. Now we're presenting fantastic audio supported by idea-driven animation to download to mobile phones."
