Signal, Image and Video Processing, 2013 In this paper, a new audio coding scheme combining the Hilbert transform and the empirical mode decomposition (EMD) is introduced. Based on the EMD, the coding is fully a data-driven approach. Audio signal is first decomposed adaptively, by EMD, into intrinsic oscillatory components called intrinsic mode functions (IMFs).

Entropy-constrained quantization of exponentially damped sinusoids parameters [PDF]
, 2011 International audienceSinusoidal modeling is traditionally one of the most popular techniques for low bitrate audio coding. Usually, the sinusoidal parameters are kept constant within a time segment but the exponentially damped sinusoidal (EDS) model is ...

A novel psychovisual model on an independent video frame for an almost lossless compression [PDF]
, 2014 A psychoacoustic model is well established in an audio coding. From the beginning of computer audio era since the previous century, an audio coding has already operated on a large one-dimensional fast Fourier transform (FFT) as a basic industrial coding.
