UAVM: Towards Unifying Audio and Visual Models [PDF]
IEEE Signal Processing Letters, vol. 29, pp. 2437-2441, 2022, 2022 Conventional audio-visual models have independent audio and video branches. In this work, we unify the audio and visual branches by designing a Unified Audio-Visual Model (UAVM). The UAVM achieves a new state-of-the-art audio-visual event classification accuracy of 65.8% on VGGSound.

Audio signal encryption using chaotic Hénon map and lifting wavelet transforms [PDF]
The European Physical Journal Plus, 2017 We propose an audio signal encryption scheme based on the chaotic Hénon map. The scheme mainly comprises two phases: one is the preprocessing stage where the audio signal is transformed into data by the lifting wavelet scheme and the other in which the ...

Clotho-AQA: A Crowdsourced Dataset for Audio Question Answering [PDF]
European Signal Processing Conference, 2022 Audio question answering (AQA) is a multimodal translation task where a system analyzes an audio signal and a natural language question, to generate a desirable natural language answer. In this paper, we introduce Clotho-AQA, a dataset for Audio question

Quantum-assisted distortion-free audio signal sensing
Nature Communications, 2022 High sensitivity in quantum sensing comes often at the expense of other figures of merit, usually resulting in distortion. Here, the authors propose a protocol with good sensitivity, readout linearity and high frequency resolution, and benchmark it ...

Forensic Analysis and Localization of Multiply Compressed MP3 Audio Using Transformers [PDF]
, 2022 Audio signals are often stored and transmitted in compressed formats. Among the many available audio compression schemes, MPEG-1 Audio Layer III (MP3) is very popular and widely used. Since MP3 is lossy it leaves characteristic traces in the compressed audio which can be used forensically to expose the past history of an audio file.

Twin neural network regression
Applied AI Letters, Volume 3, Issue 4, December 2022., 2022 We propose to reformulate a regression problem into predicting differences between target values. This allows for leveraging consistency conditions which can be used as uncertainty estimates and enable the production of an ensemble of predictions while training only a single neural network.
