A Novel Combined System of Direction Estimation and Sound Zooming of Multiple Speakers [PDF]
, 2015 This article presents a new system for estimation the direction of multiple speakers and zooming the sound of one of them at a time. The proposed system is a combination of two levels; namely, sound source direction estimation, and acoustic zooming.

A novel steganography approach for audio files [PDF]
, 2020 We present a novel robust and secure steganography technique to hide images into audio files aiming at increasing the carrier medium capacity. The audio files are in the standard WAV format, which is based on the LSB algorithm while images are ...

A Multi-Level Robust and Perceptually Transparent Blind Audio Watermarking Scheme Using Wavelets
Archives of Acoustics, 2014 In this paper, a robust and perceptually transparent single-level and multi-level blind audio watermarking scheme using wavelets is proposed. A randomly generated binary sequence is used as a watermark, and wavelet function coding is used to embed the ...

Efficient bandwidth extension of musical signals using a differentiable harmonic plus noise model
EURASIP Journal on Audio, Speech, and Music Processing, 2023 The task of bandwidth extension addresses the generation of missing high frequencies of audio signals based on knowledge of the low-frequency part of the sound. This task applies to various problems, such as audio coding or audio restoration.

Perceptually-Driven Video Coding with the Daala Video Codec [PDF]
, 2016 The Daala project is a royalty-free video codec that attempts to compete with the best patent-encumbered codecs. Part of our strategy is to replace core tools of traditional video codecs with alternative approaches, many of them designed to take ...
