Speaker Inconsistency Detection in Tampered Video

With the increasing amount of video being consumed by people daily, there is a danger of the rise in maliciously modified video content (i.e., 'fake news') that could be used to damage innocent people or to impose a certain agenda, e.g., meddle in election ...

Deep Learning of Human Perception in Audio Event Classification

Samuel Denys Beuret, Yi Yu

In this paper, we introduce our recent studies on human perception in audio event classification. In particular, the pre-trained model VGGish is used as feature extractor to process audio data, and DenseNet is trained by and used as feature extractor for o ...

Guessing the fingerings

Raphaël Nicolas Latty

On most musical instruments, especially on the guitar, it is possible to play the same note or chord in multiple ways. In this project, we develop a simple audio-based method to estimate the fingering of a note played on an acoustic guitar from a recording ...

Optimal Window and Lattice in Gabor Transform. Application to Audio Analysis.

Benjamin Ricaud

This article deals with the use of optimal lattice and optimal window in Discrete Gabor Transform computation. In the case of a generalized Gaussian window, extending earlier contributions, we introduce an additional local window adaptation technique for n ...

Approximate Compressed Sensing: Ultra-Low Power Biosignal Processing via Aggressive Voltage Scaling on a Hybrid Memory Multi-core Processor

David Atienza Alonso, Pierre Vandergheynst, Luca Benini, Hossein Mamaghanian

Technology scaling enables the design of low cost biosignal processing chips suited for emerging wireless body-area sensing applications. Energy consumption severely limits such applications and memories are becoming the energy bottleneck to achieve ultra- ...

Reverberant Audio Source Separation via Sparse and Low-Rank Modeling

Pierre Vandergheynst

The performance of audio source separation from underde- termined convolutive mixture assuming known mixing filters can be significantly improved by using an analysis sparse prior optimized by a reweighting l1 scheme and a wideband data- fidelity term, as ...

Optimization of electroacoustic resonators for semi-active room equalization in the low-frequency range

Hervé Lissek, Etienne Thierry Jean-Luc Rivet

At low frequencies, standing waves within the room cause large frequency-response variations in the listening environment, such as audio rooms or recording studios. This unwanted phenomenon has a significant impact on the sound quality of an audio system. ...

Perceptual Coding of High-Quality Digital Audio

Christof Faller, Karlheinz Brandenburg

This paper introduces high-quality audio coding using psychoacoustic models. This technology is now abundant, with gadgets named after a standard (mp3 players) and the ability to play high-quality audio from literally billions of devices. The usual paradig ...

Low distortion switched-capacitor event-driven analog to digital converter

Alexandre Schmid, Yusuf Leblebici

An event-driven tracking analog to digital converter (ADC) architecture is proposed. The proposed architecture has less sensitivity to amplifier and DAC non-linearity, reduces the swing and dynamic common-mode range requirement of the operational transcond ...
