  • Patent number: 12548584
    Abstract: An audio signal encoding/decoding method and an apparatus for performing the same are disclosed. The audio signal encoding method includes obtaining a full-band input signal, extracting a first feature vector corresponding to a first sub-band signal and a second feature vector corresponding to a second sub-band signal using an encoder neural network including a plurality of encoding layers, generating a first code vector corresponding to the first feature vector and a second code vector corresponding to the second feature vector by compressing the first feature vector and the second feature vector, and generating a bitstream by quantizing the first code vector and the second code vector.

  • Publication number: 20240194213
    Abstract: There is provided an audio processing system and method comprising an input interface that receives an input audio mixture and transforms it into a time-frequency representation defined by values of time-frequency bins, a processor that maps the values of time-frequency bins into a hyperbolic space by executing an embedding neural network trained to associate each time-frequency bin to a high-dimensional embedding and projecting each high-dimensional embedding into the hyperbolic space, and an output interface that accepts a selection of at least a portion of the hyperbolic space and renders selected hyperbolic embeddings falling within the selected portion of the hyperbolic space.
