Latest Patents

Pierre Mahe holds a patent for "Spatialized audio coding with interpolation and quantization of rotations." This patent describes a method and device for compressing audio signals that form a succession of sample frames across multiple channels in an ambisonic representation. The method involves creating a matrix of inter-channel covariance, searching for eigenvectors of this matrix, and ensuring that it represents a rotation in an N-dimensional space. If the matrix does not represent a rotation, it is corrected until a proper rotation matrix is obtained. This matrix is then applied to the audio signals before encoding them separately.
