Error Resilient Speech Coding Using Sub-band Hilbert Envelopes

Petr Motlicek, Hynek Hermansky, Sriram Ganapathy

Frequency Domain Linear Prediction (FDLP) represents a technique for auto-regressive modelling of Hilbert envelopes of a signal. In this paper, we propose a speech coding technique that uses FDLP in Quadrature Mirror Filter (QMF) sub-bands of short segment ...

MDCT for Encoding Residual Signals in Frequency Domain Linear Prediction

Petr Motlicek, Hynek Hermansky, Sriram Ganapathy

Frequency domain linear prediction (FDLP) uses autoregressive models to represent Hilbert envelopes of relatively long segments of speech/audio signals. Although the basic FDLP audio codec achieves good quality of the reconstructed signal at high bit-rates ...

Entropy coding of Quantized Spectral Components in FDLP audio codec

Petr Motlicek, Hynek Hermansky, Sriram Ganapathy

Audio codec based on Frequency Domain Linear Prediction (FDLP) exploits auto-regressive modeling to approximate instantaneous energy in critical frequency sub-bands of relatively long input segments. Current version of the FDLP codec operating at 66 kbps h ...

Spectral Noise Shaping: Improvements in Speech/Audio Codec Based on Linear Prediction in Spectral Domain

Petr Motlicek, Hynek Hermansky, Sriram Ganapathy

Audio coding based on Frequency Domain Linear Prediction (FDLP) uses auto-regressive models to approximate Hilbert envelopes in frequency sub-bands. Although the basic technique achieves good coding efficiency, there is a need to improve the reconstructed ...

Bitstream format for spatio-temporal wave field coder

Martin Vetterli, Francisco Pereira Correia Pinto

We present a non-parametric method for compressing multichannel audio data for reproduction through Wave Field Synthesis. The method consists of applying a two-dimensional filterbank to the input mul- tichannel signal, in both time and channel dimensions, ...

Autoregressive Modelling of Hilbert Envelopes for Wide-band Audio Coding

Petr Motlicek, Hynek Hermansky, Sriram Ganapathy

Frequency Domain Linear Prediction (FDLP) represents the technique for approximating temporal envelopes of a signal using autoregressive models. In this paper, we propose a wide-band audio coding system exploiting FDLP. Specifically, FDLP is applied on cri ...
