Depuis une dizaine d’années, des techniques de codage joint, exploitant les relations et les redondances entre canaux audios, ont été développées afin de réduire davantage la quantité d’information nécessaire à la représentation des signaux multicanaux. Dans cette thèse, nous étudions plus particulièrement le codage des signaux audio stéréo en l’absence d’informations à priori sur la nature des sources en présences, leur nombre et la manière dont elles sont spatialisées. Cette situation correspond à l’immense majorité des enregistrements commerciaux dans l’industrie de la musique et du multimé

Abstract:

Recent advancements in audio technology for computer games has made possible for implementations with binaural audio. Compared to regular stereo sound, binaural audio offers possibilities for a player to experience spatial sound, including sounds along the vertical plane, using their own headphones. A computer game prototype called “Crystal Gatherer” was created for this study to explore the possibilities of binaural audio imple- mentation regarding localization and perception of objects that make sound in a 3D game. The game featured two similar game levels, with the difference that one used

Résumé : Afin de répondre aux besoins de communication et de divertissement, il ne fait aucun doute que la parole et l’audio doivent être encodés sous forme numérique. En qualité CD, cela nécessite un débit numérique de 1411.2 kb/s pour un signal stéréo-phonique. Une telle quantité de données devient rapidement prohibitive pour le stockage de longues durées d’audio ou pour la transmission sur certains réseaux, particulièrement en temps réel (d’où l’adhésion universelle au format MP3). De plus, ces dernières années, la quantité de productions musicales et cinématographiques disponibles en cinq

Abstract:

This dissertation presents an optical approach for reproducing stereo audio from the stereo disc phonograph records (LPs). Since the late nineteenth century, as one of the most influential recording technologies, the phonograph recording has enjoyed its popularity and produced numerous cylinders and discs that carry speeches, music, and all kinds of audio cultural heritage. The preservation of phonograph sound recordings is thus of world-wide concern. This research provides an alternative approach to digitizing the stereo disc phonograph records, potentially for long-term preservation, by opti

This thesis presents a stereo coding architecture for the ITU-T G.719 fullband mono codec. G.719 is suitable for teleconferencing applications with a competitive audio quality for speech and audio signals that are encoded at 32, 48 and 64 kbps. The proposed stereo architecture comprises parametric stereo coding where the spatial properties of the stereo channels are modeled with the use of parameters, which are encoded and transmitted to the decoder together with an encoded downmix of the stereo channels. The stereo architecture has been implemented in MATLAB with an external mono coding using

Abstract:

The identification of the melody from a music recording is a relatively easy task for humans, but very challenging for computational systems. This task is known as "audio melody extraction", more formally defined as the automatic estimation of the pitch sequence of the melody directly from the audio signal of a polyphonic music recording. This thesis investigates the benefits of exploiting knowledge automatically derived from data for audio melody extraction, by combining digital signal processing and machine learning methods. We extend the scope of melody extraction research by working

However, the required storage of high quality digital audio is usually massive. As for the compact disc signals (sampling rate of 44.1 kHz and 16 bits/sample), the bitrate requirement is 44100 * 16 =705.6 kb/s per channel and 1.41 Mb/s for stereo audio, which is too high for most applications.
