Robust equalization of multichannel acoustic systems [PDF]

, 2010
In most real-world acoustical scenarios, speech signals captured by distant microphones from a source are reverberated due to multipath propagation, and the reverberation may impair speech intelligibility.

An investigation into the efficacy of methods commonly employed by mix engineers to reduce frequency masking in the mixing of multitrack musical recordings [PDF]

, 2015
Studio engineers use a variety of techniques to reduce frequency masking between instruments when mixing multi-track musical recordings. This study evaluates the efficacy of three techniques, namely mirrored equalization, frequency spectrum sharing and ...

Robust Audio Copy-Move Forgery Detection Using Deep Keypoint Features on High-Resolution Texture Images

IEEE Access
Audio Copy-Move Forgery (ACMF) is a critical security problem that compromises the integrity of digital audio recordings and complicates forensic investigations. Traditional methods based on time-frequency analyses cannot reliably detect the forged parts

Valutazione in ambienti reali di un sistema immersivo multibanda mediante array lineare di altoparlanti - Evaluation in real environments of a multiband immersive system using a linear loudspeaker array

Rivista Italiana di Acustica, 2019
Un sistema audio-immersivo permette di creare delle sorgenti audio virtuali che non esistono nell’ambiente fisico reale. In questo articolo viene implementato un sistema multibanda in grado di riprodurre una sensazione di immersività, sfruttando un array
