USAC-3D support
Hi, thank you for the great work on the USAC encoder. I was wondering how much work would it be to add USAC-3D encoding and decoding support? USAC-3D is somewhat introduced in this paper - https://ieeexplore.ieee.org/stamp/stamp.jsp?arnumber=7056445, it is a part of the broader ISO/IEC 23008-3:2019 standard that also defines the container and the format for the metadagta.
Complete encoding and decoding (i.e., the audio objects and the 2/5.1/7.1 mixes) would be best suited for a complete spatial audio solution (that would output to a spatial audio renderer like ISpatialAudioClient but the USAC-3D encoded audio streams itself would be a great start.
