Generating a stereophonic presentation from a monophonic audio signal is a challenging
open task, especially if the goal is to obtain a realistic spatial imaging with a specific panning …

An apparatus for extracting an ambient signal from an input audio signal comprises a gain-
value determinator configured to determine a sequence of time-varying ambient signal gain …

The predominant melodic source, frequently the singing voice, is an important component of
musical signals. In this paper, we describe a method for extracting the predominant source …

When a monophonic source signal is projected from two or more loudspeakers, listeners
typically perceive a single, phantom source, positioned according to the relative signal …

The goal of source separation is to detect and extract the individual signals present in a
mixture. Its application to sound signals and, in particular, to music signals, is of interest for …

Neural upmixing, the task of generating immersive music with an increased number of
channels from fewer input channels, has been an active research area, with mono-to-stereo …

ABSTRACT A method for upmixing of single-channel audio signals for stereophonic sound
reproduction in real-time is presented. To this end, the input signal is decomposed into a …

We exploited deep neural networks (DNN) for two-to-five channel surround decoding.
Specifically DNNs are used to replace the primary-ambient separation and ambient …

Sound source separation techniques are known to be very useful in many applications. High
fidelity and audio oriented applications are a challenging issue in this topic, however …

Music is built from sound, ultimately resulting from an elaborate interaction between the
sound-generating properties of physical objects (ie music instruments) and the sound …
