    • Acoustic event detection and localization using distributed microphone arrays 

      Chakraborty, Rupayan (Universitat Politècnica de Catalunya, 2013-12-18)
      Doctoral thesis
      Open Access
      Automatic acoustic scene analysis is a complex task that involves several functionalities: detection (time), localization (space), separation, recognition, etc. This thesis focuses on both acoustic event detection (AED) ...

    • Joint model-based recognition and localization of overlapped acoustic events using a set of distributed small microphone arrays 

      Chakraborty, Rupayan; Nadeu Camprubí, Climent (2017-12-19)
      External research report
      Open Access
      In the analysis of acoustic scenes, often the occurring sounds have to be detected in time, recognized, and localized in space. Usually, each of these tasks is done separately. In this paper, a model-based approach to ...

    • Joint recognition and direction-of-arrival estimation of simultaneous meeting-room acoustic events 

      Chakraborty, Rupayan; Nadeu Camprubí, Climent (2013)
      Conference report
      Restricted access - publisher's policy
      Acoustic scene analysis usually requires several sub-systems working in parallel for carrying out the various required functionalities. Focusing to a more integrated approach, in this paper we present an attempt to jointly ...

    • Model-based processing for acoustic scene analysis 

      Nadeu Camprubí, Climent; Chakraborty, Rupayan; Wolf, Martin (Institute of Electrical and Electronics Engineers (IEEE), 2014)
      Conference report
      Restricted access - publisher's policy
      The analysis of acoustic scenes requires several functionalities, being perhaps recognition (speech, speaker, other acoustic events) and spatial localization the two most relevant ones. For a reduced invasiveness, ...

    • Real-time multi-microphone recognition of simultaneous sounds in a room environment 

      Chakraborty, Rupayan; Nadeu Camprubí, Climent (Institute of Electrical and Electronics Engineers (IEEE), 2013)
      Conference report
      Restricted access - publisher's policy
      Time overlapping of acoustic signals, which so often occurs in real life, is a challenge for current state-of-the-art sound recognition systems. In this work, we propose an approach for detecting, identifying and ...

    • Sound-model-based acoustic source localization using distributed microphone arrays 

      Chakraborty, Rupayan; Nadeu Camprubí, Climent (Institute of Electrical and Electronics Engineers (IEEE), 2014)
      Conference report
      Restricted access - publisher's policy
      Acoustic source localization and sound recognition are common acoustic scene analysis tasks that are usually considered separately. In this paper, a new source localization technique is proposed that works jointly with an ...

    • Source ambiguity resolution of overlapped sounds in a multi-microphone room environment 

      Chakraborty, Rupayan; Nadeu Camprubí, Climent; Butko, Taras (2014-04)
      Article
      Open Access
      When several acoustic sources are simultaneously active in a meeting room scenario, and both the position of the sources and the identity of the time-overlapped sound classes have been estimated, the problem of assigning ...
