Audio Inpainting in Time-Frequency Domain with Phase-Aware Prior
Peter BaluÅ¡Ãk, Peter Balušík, Pavel Rajmic
We address the problem of time-frequency audio inpainting, where the goal is to fill missing spectrogram portions with consistent information. Despite recent advances, existing app…
Audio dequantization using instantaneous frequency
VojtÄch Kovanda, Pavel Rajmic
We present a dequantization method that employs a phase-aware regularizer, originally successfully applied in an audio inpainting problem. The method promotes a temporal continuity…
A MATLAB toolbox for Computation of Speech Transmission Index (STI)
Pavel Rajmic, JiÅÃ Schimmel, Å imon Cieslar
The speech transmission index (STI) is a popular simple metric for the prediction of speech intelligibility when speech is passed through a transmission channel. Computation of STI…
Janssen 2.0: Audio Inpainting in the Time-frequency Domain
OndÅej Mokrý, Peter BaluÅ¡Ãk, Pavel Rajmic
The paper focuses on inpainting missing parts of an audio signal spectrogram, i.e., estimating the lacking time-frequency coefficients. The autoregression-based Janssen algorithm,…
Tweaking autoregressive methods for inpainting of gaps in audio signals
OndÅej Mokrý, Pavel Rajmic
A novel variant of the Janssen method for audio inpainting is presented and compared to other popular audio inpainting methods based on autoregressive (AR) modeling. Both conceptua…
Dequantization of a signal from two parallel quantized observations
VojtÄch Kovanda, Pavel Rajmic
We propose a technique of signal acquisition using a combination of two devices with different sampling rates and quantization accuracies. Subsequent processing involving sparsity…
