International Journal of Digital Multimedia Broadcasting, Volume 2019, Issue 1, 2019., 2019 Audio data compression has revolutionised the way in which the music industry and musicians sell and distribute their products. Our previous research presented a novel codec named ACER (Audio Compression Exploiting Repetition), which achieves data reduction by exploiting irrelevancy and redundancy in musical structure whilst generally maintaining ...

Real‐Time Audio‐Visual Analysis for Multiperson Videoconferencing
Advances in Multimedia, Volume 2013, Issue 1, 2013., 2013 We describe the design of a system consisting of several state‐of‐the‐art real‐time audio and video processing components enabling multimodal stream manipulation (e.g., automatic online editing for multiparty videoconferencing applications) in open, unconstrained environments.

Direct Modelling of Magnitude and Phase Spectra for Statistical Parametric Speech Synthesis [PDF]
, 2017 We propose a simple new representation for the FFT spectrum tailored to statistical parametric speech synthesis. It consists of four feature streams that describe magnitude, phase and fundamental frequency using real numbers.

Perceptual Optimization of Room-In-Room Reproduction with Spatially Distributed Loudspeakers [PDF]
, 2014 It is often desirable to reproduce a specific room-acoustic scene, e.g. a concert hall in a playback room, in such a way that the listener has a plausible and authentic spatial impression of the original sound source including the room acoustical ...

Wavenet based low rate speech coding
, 2017 Traditional parametric coding of speech facilitates low rate but provides poor reconstruction quality because of the inadequacy of the model used. We describe how a WaveNet generative speech model can be used to generate high quality speech from the bit ...

Efficient Phantom Source Widening and Diffuseness in Ambisonics [PDF]
, 2014 Object-based spatial audio considers virtual sound sources having a width/diffuseness parameter. This parameter aims at controlling the perceived width or diffuseness of the auditory object, or phantom source, created by the renderer.
