    "abstract": "With the advancements of VR environments and 360-degree video, ambisonics have reemerged as an important technique in providing immersive audio experiences. An alternative to channel based 3D sound, ambisonics represent full-sphere sound independent of loudspeaker location. This paper discusses how open-source compression technologies can efficiently transport audio for next-generation immersive media. Two open source codecs, Vorbis and Opus, are compared to AAC for first-order ambisonics. The presented work shows that open and free audio compression is reasonable and promising for delivery of spatial audio content over Internet.",
