Towards a model of how designers mentally categorise design information [PDF]

, 2010
This study aims to explore how designers mentally categorise design information during the early sketching performed in the generative phase. An action research approach is particularly appropriate for identifying the various sorts of design information ...

Auditory Localization in Low-Bitrate Compressed Ambisonic Scenes

Applied Sciences, 2019
The increasing popularity of Ambisonics as a spatial audio format for streaming services poses new challenges to existing audio coding techniques. Immersive audio delivered to mobile devices requires an efficient bitrate compression that does not affect ...

Objective assessment of region of interest-aware adaptive multimedia streaming quality [PDF]

, 1982
Adaptive multimedia streaming relies on controlled adjustment of content bitrate and consequent video quality variation in order to meet the bandwidth constraints of the communication link used for content delivery to the end-user.

Frame Theory for Signal Processing in Psychoacoustics

, 2016
This review chapter aims to strengthen the link between frame theory and signal processing tasks in psychoacoustics. On the one side, the basic concepts of frame theory are presented and some proofs are provided to explain those concepts in some detail ...

Contributions of temporal encodings of voicing, voicelessness, fundamental frequency, and amplitude variation to audiovisual and auditory speech perception [PDF]

, 1999
Auditory and audio-visual speech perception was investigated using auditory signals of invariant spectral envelope that temporally encoded the presence of voiced and voiceless excitation, variations in amplitude envelope and F-0.

A simple lossy audio coding scheme based on the DWT [PDF]

, 2007
This paper proposes a simple scheme for audio coding that does not use perceptual models. The audio coder is based on the discrete wavelet transform to decorrelate signals, computed through the lifting scheme, and followed by Huffman coding.

Perceptually adaptive bit-plane coding for scalable audio

Electronics Letters, 2007
A simple and flexible bit-plane coding method is developed for scalable audio coding. It is different from the traditional bit-plane coding in that the optimal bit-plane scanning order is adapted to the scale between the energy of the residual signal and the audio mask.
