Ambisonics Comes of Age

Ambisonic representation provides a relatively versatile and compact way of storing or transmitting spatial audio scenes. Signals in this format may exist in mixed orders, requiring special decoders to be constructed that optimize spatial rendering. When it comes to decoding ambisonics for different speaker layouts, there may be advantages to active or hybrid decoders. Irregular layouts are harder to decode for than regular ones. Binaural rendering is a popular means of reproducing ambisonic content, and there is some evidence that individualized HRTF processing is useful in this context. Ambisonic information can also be data compressed, and there may be advantages to doing this after some form of signal decomposition has been done, which takes advantage of interchannel redundancy.
