3D audio is the digital recreation of sound we hear everyday in the real world. It’s always around us and it can come from any direction. This is what we call spatial sound. It combines the interactions between acoustic sound waves, the space and interactions with our head and ears.
Most immersive audio concepts have existed for decades. But the interest in immersive audio has increased enormously in recent years due to the growing popularity of stand-alone audio experiences such as podcasts, virtual reality (VR) and augmented reality (AR).
It has also become more accessible. Today it’s possible to experience immersive audio with just your phone and an ordinary set of earplugs.
Recording techniques I like to use.
Ambisonics: A multi-channel technique that allows you to capture sound from all directions spherically from one spatial point. To play this view, the audio is rendered binaurally, making it possible to virtually rotate the perspective orientation in all directions, horizontally and vertically.
Ambisonics is supported by the handy post-production and playback tools currently on the market. That is why ambisonics is the right tool for Virtual Reality and all other applications that use 3D audio. It is a tool for creating new worlds of sound.
Hardware I like to use: Sennheiser AMBEO and Rode NT-SF1
