Two-Dimensional Quantization for Geometry-Aware Audio Coding

In three linesQ2D2 (Two-Dimensional Quantization) is a novel quantization scheme for neural audio codecs. It projects feature pairs onto structured 2D grids (hexagonal, rhombic, rectangular) to improve compression efficiency, token rates and codebook utilization while maintaining state-of-the-art reconstruction quality across speech, audio and music domains.
