Today's efficient audio codecs for low bitrate application scenarios often rely on parametric coding of the upper frequency band portion of a signal while the lower frequency band portion of the same is conveyed by a waveform preserving coding method. At the decoder, the upper frequency signal is approximated from the lower frequency data using the upper frequency …

abstract={the compression ratio of core-encoder can be improved significantly by reducing the bandwidth of the audio signal, resulting in the poor listening perception. this paper proposes a bandwidth extension method based on generative adversarial nets (gan) for extending the bandwidth of an audio signal, to create a more natural sound. the method uses gan as a …

Perceptual audio coding at low bit rates often relies on semi-parametric or parametric techniques to efficiently transmit and restore audio content that, after receiving, may be very different to the original in its waveform, but is perceptually still very close to it. Audio bandwidth extension exploits the limited resolution of the human auditory perception at high …
