Audio Decoding by Inverse Problem Solving
Pedro J. Villasana T., Lars Villemoes, Janusz Klejsa +1
We consider audio decoding as an inverse problem and solve it through diffusion posterior sampling. Explicit conditioning functions are developed for input signal measurements prov…

Source coding of audio signals with a generative model
Roy Fejgin, Janusz Klejsa, Lars Villemoes +1
We consider source coding of audio signals with the help of a generative model. We use a construction where a waveform is first quantized, yielding a finite bitrate representation.…

High-quality speech coding with SampleRNN
Janusz Klejsa, Per Hedelin, Cong Zhou +2
We provide a speech coding scheme employing a generative model based on SampleRNN that, while operating at significantly lower bitrates, matches or surpasses the perceptual quality…
