AB  - Ambisonics Audio has become the primary format to transmit and reproduce audio in immersive or interactive content including 360 video and virtual reality due to its flexibility to be decoded to various speaker configuration and listener’s orientation. However, one of the drawbacks of encoding a sound field to Ambisonics audio is the loss of its spatial precision. Higher order Ambisonics has been developed to use more channels in exchange of better precision. In this brief we present a method to detect and extract directional sound from an encoded Ambisonics mix. Improved extraction of the directional signal can improve the performance of other systems, for example the spatial precision during reconstruction.
