The start-up, which specialises in virtual reality (VR) audio, has been bought by the social networking giant for an undisclosed sum.
Two Big Ears Limited was founded in March 2013 by Abesh Thakur and Varun Nair, both graduates of the University of Edinburgh.
Abesh Thakur, said: “We’ve been hard at work creating technology and tools that have defined how immersive audio is crafted and experienced in VR and AR both now and in the future.
“We’re proud to see the impact our work has had on so many great projects.
“Now, we’re ready to take the next step on our journey and scale our work from within Facebook. There is so much still to explore.
“By joining with a company that shares our values and our vision, we will be able to scale our technology even quicker as we continue powering immersive audio experiences.”
From today, Two Big Ears’ pipeline for cinematic VR and 360 video, including the authoring tools, encoder and rendering engine are available for free.
The company is looking to the future, as they aim to continue their work developing VR tools on a global scale and create state of the art VR audio.
Abesh Thakur said: “Thank you to our customers, partners and investors, including board members George Elliott and Neil Heywood, the University of Edinburgh, Scottish Enterprise and everybody who has been with us on this amazing journey.”
