The tools that we've developed are also now available to BBC staff for use in studios and outside broadcasts, allowing them to produce binaural sound without our input. We have developed training resources with the BBC Academy based on the experience we've gained through this work, including some public resources that are linked to below. More recently we collaborated with the BBC's VR Hub to produce the spatial audio mix for the VR experience Nothing to be Written. We developed the BBC's first public VR experience, The Turning Forest, which won the 2016 TVB Europe award for Achievement in Sound. We have supported the production of several award-winning binaural audio dramas, such as Sky Is Wider (unfortunately, this is no longer available to listen) and iSpy Sound Detective. This uses a custom live mixing tool that we built. The 2019 concerts are available in binaural here. We have now supported the BBC to make well over 100 programmes using binaural sound techniques, across a wide range of genres, for radio and podcasts, television, and in new interactive content.įor several years running we have enabled production of special immersive headphones mixes of the BBC Proms. To adapt this for broadcasting requires new techniques based on a better understanding of human hearing. Achieving high quality binaural sound currently requires careful measurement and specialist equipment. Natural binaural reverberation is also important for convincing effect. Every person has an individual pattern of hearing cues that are created by their unique body shape, also these cues change as a listener moves. Our hearing system appears to be sensitive to inaccurate cues, it is common for binaural filters to create an unconvincing spatial impression as well as poor sound quality. ![]() ![]() Audio signals are filtered to introduce these cues and give the impression that a sound source is located outside of the head at a given location in space.
