Title: Method and apparatus for encoding and decoding successive frames of ambisonics representation of two- or three-dimensional sound field
Inventor: PETER JAX
IPC: G10L19/00
Filed: 2020-02-27
Abstract: To solve problems in which representations of spatial audio scenes using higher-order Ambisonics (HOA) technology typically require a large number of coefficients per time instant and this data rate is too high for most practical applications that require real-time transmission of audio signals.SOLUTION: The compression is carried out in the spatial domain instead of the HOA domain. The (N+1)input HOA coefficients are transformed into (N+1)equivalent signals in the spatial domain, and the resulting (N+1)time-domain signals are input to a bank of parallel perceptual codecs. At the decoder side, the individual spatial-domain signals are decoded, and the spatial-domain coefficients are transformed back into the HOA domain in order to recover the original HOA representation.SELECTED DRAWING: Figure 8
