A boutique audio post-production studio based in Silver Spring, Maryland with two client suites, a Dolby Atmos® mix suite, a surround sound mix suite, a recording/foley booth.  Our team of staff sound engineers have over 50 years of combined experience and each maintains a remote mixing location to accommodate the constant pace of today’s marketplace.  We also provide remote review sessions - allowing instant collaboration with clients all over the world whether they’re traveling for production, based internationally or working from home.  Though we have our home base studio, we are truly location agnostic!

While immersive mixing for Nature Documentaries in Dolby Atmos® is one of our favorites, we love the variety of our projects and clients.  We mix promos for broadcast & radio, episodic programming, experiential immersive museum films, documentaries & web videos.  Full finishing services are offered in close collaboration with our color partner, DC Color. OHA stays on the forefront of new technologies and mediums; assuring that we will always be able to deliver creative and effective audio.
