The propagation of sound in a shallow water environment is characterized by boundary
reflections from the sea surface and sea floor. These reflections result in multiple (indirect) …

Speech enhancement is a core problem in audio signal processing with commercial
applications in devices as diverse as mobile phones, conference call systems, smart …

Supervised learning methods are a powerful tool for direction of arrival (DOA) estimation
because they can cope with adverse conditions where simplified models fail. In this work, we …

The performance of conventional direction-of-arrival (DOA) estimation methods degrades
greatly when there are few snapshots and the noise model is mismatched, especially in …

The problem of speaker tracking in noisy and reverberant enclosures is addressed in this
paper. We present a hybrid algorithm, combining traditional tracking schemes with a new …

Many speech dereverberation techniques require an estimate of the late reverberation
power spectral density (PSD). State-of-the-art multichannel methods for estimating the late …

Underwater acoustic sensor networks (UASNs), which are popular in various application
fields, including marine resources development, environmental exploration, seismic …

Acoustic reverberation is one of the most relevant factors that hampers the localization of a
sound source inside a room. To date, several approaches have been proposed to deal with …

Accurate direction of arrival (DoA) estimation is paramount in various fields, from
surveillance and security to spatial audio processing. This work introduces an innovative …

An off-the-shelf drone for indoor operation would come with a variety of different sensors that
are used concurrently to avoid collision with, eg, walls, but these sensors are typically uni …
