Reverse audio engineering for active listening and other applicationsGorlow, Stasnislaw 16 December 2013 (has links) (PDF)
This work deals with the problem of reverse audio engineering for active listening. The format under consideration corresponds to the audio CD. The musical content is viewed as the result of a concatenation of the composition, the recording, the mixing, and the mastering. The inversion of the two latter stages constitutes the core of the problem at hand. The audio signal is treated as a post-nonlinear mixture. Thus, the mixture is "decompressed" before being "decomposed" into audio tracks. The problem is tackled in an informed context: The inversion is accompanied by information which is specific to the content production. In this manner, the quality of the inversion is significantly improved. The information is reduced in size by the use of quantification and coding methods, and some facts on psychoacoustics. The proposed methods are applicable in real time and have a low complexity. The obtained results advance the state of the art and contribute new insights.

Reverse audio engineering for active listening and other applications / Rétroingénierie du son pour l’écoute active et autres applicationsGorlow, Stasnislaw 16 December 2013 (has links)
Ce travail s’intéresse au problème de la rétroingénierie du son pour l’écoute active. Le format considéré correspond au CD audio. Le contenu musical est vu comme le résultat d’un enchaînement de la composition, l’enregistrement, le mixage et le mastering. L’inversion des deux dernières étapes constitue le fond du problème présent. Le signal audio est traité comme un mélange post-non-linéaire. Ainsi, le mélange est « décompressé » avant d'être « décomposé » en pistes audio. Le problème est abordé dans un contexte informé : l’inversion est accompagnée d'une information qui est spécifique à la production du contenu. De cette manière, la qualité de l’inversion est significativement améliorée. L’information est réduite de taille en se servant des méthodes de quantification, codage, et des faits sur la psychoacoustique. Les méthodes proposées s’appliquent en temps réel et montrent une complexité basse. Les résultats obtenus améliorent l’état de l’art et contribuent aux nouvelles connaissances. / This work deals with the problem of reverse audio engineering for active listening.
