a movie theatre experience on the go 

It's a fact that nowadays the majority of consumers are listening to their entertainment on stereo speakers and headphones using various devices. But, most of the content is mixed in surround to provide audiences for the best theatrical experience. 

However, going from surround sound to stereo with a regular fold down is a far cry from the intended experience.

Sfera Post has the solution to keep that same cinematic quality in stereo.

Sfera Post introduces a revolutionary new spacial audio process that enhances
your folded down stereo file to sound just like your original 5.1 theatrically mix
ed project. This means that you can actually hear the rear speakers like they're physically behind you, but in stereo... Let that sink in.

Keep a Modest Head is a Canadian short documentary film, directed by Deco Dawson and released in 2012.  The film is a tribute to Jean Benoît, a Canadian artist often credited as "the last surrealist". The film premiered at the 2012 Toronto International Film Festival, where it won the Toronto International Film Festival Award for Best Canadian Short Film. TIFF subsequently named the film to its year-end Canada's Top Ten list of short films. The film was a shortlisted Canadian Screen Award finalist for Best Short Documentary Film at the 1st Canadian Screen Awards. The film was originally mixed in 5.1 and uses the surround techniques to totally immerse the audience in a whimsical story to illustrate the life of Jean Benoît, the last official member of the highly influential Surrealist group.
