In our technology called 'Full-Spherical Stereo (https://www1.doshisha.ac.jp/~bioinfo/panoramic/FS_stereo.html),' full-spherical spatial information of sounds can be saved to and transmitted in a conventional stereo audio format.

Since three dimensional spatial information can be acquired by a 4-point measurement, full-spherical (3D) spatial sounds can be obtained with a tetrahedral microphone system that consists of 4 omnidirectional microphones.  

The 4 tracks of the recorded data streams were converted to a conventional stereo format by the Full-Spherical Stereo technology. Three-dimensional spatial information of the recorded sounds is mostly preserved in this conversion.

If there are 2 or more tetrahedral microphone systems in a scene, spatial information at any desired point around them can be estimated by the method that we call 'Panoramic sound morphing.' Because of Panoramic sound morphing, the listener can seamlessly move his or her listening point during the reproduction of sounds. 

Sounds in this app were recorded with 2 tetrahedral microphone systems that were placed in the scene and the listener can interactively control the listening point and panning by the controllers on the app screen.
