3D echo cancellation in a home environment
… of echoes in a home environment, where the room impulse response is unknown and variable. The general problem, where the speaker's movements are completely unrestricted, is a very hard one, and research in this area has only begun in the last several years. Therefore, this thesis addresses a …

Single-Microphone Speech Dereverberation: Modulation Domain Processing and Quality Assessment
… (LRSV) from time domain LRSV using a statistical room impulse response (RIR) model and implements spectral subtraction in the modulation domain. On one hand, different from acoustic domain spectral subtraction, our method implements spectral subtraction in the modulation domain, which has been …

CUSTOMIZING IMMERSIVE SPATIAL AUDIO: FROM INDIVIDUALIZED BINAURAL RENDERING TO REAL-VIRTUAL ACOUSTIC BLENDING
… a una risposta all'impulso della stanza (room impulse response, RIR) di riferimento. In questo modo, la riverberazione di sorgenti sonore virtuali arbitrarie è coerente con le proprietà acustiche di un ambiente esistente. Il metodo è stato valutato in un esperimento di co-immersione di …

The creation of a binaural spatialization tool
… different characteristics in terms of frequency response and reverb time; • The creation of a real-time and offline binaural spatialization application, imple-menting the techniques cited in the previous points, and including a set of multichannel(and Ambisonics)-to-binaural conversion tools. • …

An investigation of the utility of monaural sound source separation via nonnegative matrix factorization applied to acoustic echo and reverberation mitigation for hands-free telephony
… to maintain that performance during and after room changes for similar computational requirements. Speaker extraction is also shown to introduce distortion of the near-end speech signal during double-talk, which is quantified by means of a speech distortion measure and compared to that of AEC. …

Room reconstruction and navigation using acoustically obtained room impulse responses and a mobile robot platform
… into the environment and records the resulting response. This response is processed to gain information on the robot's immediate surroundings. Previous work done in this area focused on the recording and processing aspect to determine the location of a sound source or multiple sound sources. We …
