Description
Acoustic Scenes and EventsSarti, MezzaDetection of anomalous sounds in domestic environmentsFull thesisThe objective is the development of intelligent systems capable of monitoring a domestic environment to detect acoustic anomalies. The idea is to learn a suitable "normal state" for the monitored soundscape and to track the deviations thereof with minimal or no supervision.
Audio ForensicsBestaginiAnalysis of MP3 audio files metadata and structureFull thesisForensic analysis of multimedia objects can be performed by observing the way a file is structured and saved to disk, rather than analyzing the actual content. For instance, the analysis of MP4 video containers can provide valuable information related to video origin (https://arxiv.org/pdf/2101.10795v1.pdf). The goal of this work is to dig into the structure of an MP3 audio file to extract possible information related to the used encoder, device, or presence of tampering.

Audio signal processing
Sarti, Giampiccolo, BernardiniImplementation of Wave Digital scattering matrices absorbing controlled sources Full thesisIn the Wave Digital domain, topological scattering junctions can absorb certain nonreciprocal elements. The thesis concerns the derivation of formulas for the efficient computation of their scattering matrices, such that they can be exploited for Virtual Analog applications.
Audio signal processing
Sarti, Bernardini, Mezza, GiampiccoloModeling Nonlinear Functions with Hysteresis in the Wave Digital DomainFull thesisEfficiently modeling hysteretic curves is still today an open field of research. The aim of the thesis is to model such multivariate functions in the Wave Digital domain by using RNNs. Possible applications range from circuit simulation to Virtual Analog modeling (e.g., nonlinear modeling of audio transformers).
Music informaticsSarti, Mezza, ComanducciAudio prediction for Networked Music Performance Full thesisIn recent years, live music performances over the Internet have become a reality. However, the inevitable network packets loss is still affecting the experience in a significant way, causing abrupt interruptions and glitches in the audio stream. In this respect, we aim at developing new deep learning-based techniques that would tackle this issue by predicting the next few milliseconds of audio, while ensuring the high quality and seamlessness of the reconstructed music signal.
Musical acousticsAntonacci, GonzalezEffect of arching in the vibrational response of violin top plates (or full violins)Full thesis Recently, we have studied how the outline, thickness and material parameters affect the vibrational response of free violin top plates. The objective of this thesis is to study the effect of the arching profile in the vibrational response. For a short thesis it would be to reproduce the results of our last paper including the arching, for a longer thesis we would study the complete violin not only the top plate.
Musical acousticsAntonacci, GonzalezSimulating the bridge admittance of complete violins in Comsol
Full thesisBridge admittance (the frequency response function measured at the bridge) is one of the easiest and most informatives experiments that are currently done with violins. The objective of this thesis is to simulate this measurement in Comsol for a data set of 2000 virtual violins and study the correlations between the violin parameters and the bridge admittance.
Musical acousticsAntonacci, GonzalezDesign and production of 3D printed / CNC luthier toolsFull thesisLuthier tools are exremely specialised and expensive. This project looks into creating open source designs for luthier specific tools that can be 3D printed or carved from solid material with a CNC.
Musical acousticsAntonacci, GonzalezMetamaterials for guitarmakingFull thesisDouble top guitars are changing the world of guitar making. By convining engineered metamaterials with classical guitarmaking one can overcome some of the limitations of wood when making a guitar. This thesis will study by means of simulations (and experiments Covid allowing) the use of metamaterials in guitarbuilding.
Musical acousticsOlivieri, Gonzalez, AntonacciTowards white-box data-driven methods for Near-field Acoustic HolographyFull thesisNear-field Acoustic Holography (NAH) is a powerful technique to study the velocity field on vibrating objects in a contactless way (e.g., without accelerometer sensors). Recently, we developed a fully data-driven approach for NAH with Convolutional Neural Networks which can increase the performances of previous state-of-the-art methods. The goal of this thesis is to investigate and understand what the networks learned, in order to transform the current black box methodology towards a white box one.
Networked Music PerformanceSarti, ComanducciAdaptive haptic metronomes for networked music performancesFull thesisNetworked Music Performances have become a big part of how musicians rehearse or perform together. The main issue during a NMP is the latency due to the network. In order to tackle this issue we have developed an adaptive metronome, i.e. a metronome able to change its tempo by following the tempo of the musicians. The goal of this thesis is to combine it with Haptic devices in order to provide the tempo indication via vibrotactile stimuli. This thesis will be co-supervised with the Università di Trento (UniTrento) all will (hopefully) include experiments with real musicians.
Musical acousticsAntonacci, Pezzoli, MalvermiPrediction of new Frequency Response Functions through Convolutional Neural NetworksFull thesis, Short thesisRecently we have successfully applied CNNs to perform interpolation of Frequency Response Functions in rectangular plates also when dealing with random measurement locations. The thesis has as first target (short version) the extension of the method for real case scenarios (few initial measurements, violin plates, reconstruction of both real and imaginary part), then a new formulation exploting physics can be planned (long version).
Differential Microphone ArraysSarti, Bernardini, AlbertiniEvaluation of phase, gain, and misplacement errors on arbitrary geometry differential microphone arraysFull thesisDifferential Microphone Arrays (DMAs) are small-sized microphone arrays known for their almost frequency-invariant beampatterns and superdirective responses. Recently developed arbitrary geometry DMAs represent a generalization of traditional DMAs, allowing to form spatial filters with any random microphone distribution. The aim of the Thesis is to model the effect of phase, gain and misplacement errors on the arbitrary geometry DMA performance, and develop a method to compensate such errors. Characterization of real sensors is a possibility.
Musical acoustics / AIGonzalez, AI-powered pick up: making guitars sound great againFull thesisGuitar pick-ups suck. In this thesis we want to use artificial intelligence to, in real time, make a neural network to enhance the signal acquired by the pick ups to sound like the acoustic signal captured from a mic. The thesis work will involve aquiring data for the training, developing the network, and eventually build a hardware prototype.
Differential Microphone ArraysSarti, Bernardini, AlbertiniMultistage Beamforming with Differential Microphone ArraysFull thesisDifferential Microphone Arrays (DMAs) are small-sized microphone arrays known for their almost frequency-invariant beampatterns and superdirective responses. Recently, two-stage spatial filtering (beamforming) using DMAs have been introduced. Multistage beamforming allows to obtain directivity patterns which are almost equal to the product of each spatial filtering stage beampattern. The aim of the Thesis is to develop a general N-stage beamformer and evaluate its properties in terms of directionality and robustness against noise.

Description
Tubaro, Lipari, PicettiImproving Full Waveform Inversion with CNNsFull/shortFull Waveform Inversion reconstructs the subsurface velocities from a set of measurements. It is very expensive, time-consuming and prone to a number of tips and tricks for avoiding local minima, numerical instability and optimization errors.
Tubaro, Lipari, PicettiDenoising and Interpolation of seismic data through CNNsFull/shortThe amount of data is constantly increasing and the areas of interest are more and more complex to analyze. Moreover, they require a subsurface mapping at increasingly higher resolution and higher fidelity. Can CNNs help this process?
Tubaro, Lipari, PicettiMachine Learning guided Seismic InterpretationFull/shortHuman experts visually inspects seismic images looking for subsurface features. On the other hand, Machine Learning techniques have proven to be effective in image segmentation (i.e., recognizing objects and targets from a set of pixels). Can we merge these two worlds?
Tubaro, Lipari, PicettiPhysics-aware Transfer LearningFull/shortCan a neural network learn Physics?
Tubaro, Lipari, PicettiRegularizing Traveltime Tomography via Machine LearningFull/shortTraveltime Tomography is an important tool for localizing subsurface events, both in medical and geophysical imaging. The tomography problem is a ill-posed and ill-conditioned inverse problem, which suffers a lot from numberical instability, local minima, and noise. Here's where the machine learning comes into play!
