• Sacral sound-engineering

  Publikacja

  • G. Budzyński

  - Archives of Acoustics - Rok 2011

  Organologic and campanologic acoustical problems due to applications to sacral objects are characterized on ground of numerous reviewed publications and engineering reports. Participations of several involved research centres, mostly Polish, at solving these problems are evaluated. Some desirable future developments are indicated. Appendices bring examples of documentation on selected investigated objects.

  • A. Czyżewski

  - Rok 2010

  An automatic surveillance system, based on event detection in the video image can be improved by implementing algorithms for audio analysis. Dangerous or illegal actions are often connected with distinctive sound events like screams or sudden bursts of energy. A method for detection and classification of alarming sound events is presented. Detection is based on the observation of sudden changes in sound level in distinctive sub-bands...

• Automatic sound recognition for security purposes

  Publikacja

  • P. Żwan

  - Rok 2008

  In the paper an automatic sound recognition system is presented. It forms a part of a bigger security system developed in order to monitor outdoor places for non-typical audio-visual events. The analyzed audio signal is being recorded from a microphone mounted in an outdoor place thus a non stationary noise of a significant energy is present in it. In the paper an especially designed algorithm for outdoor noise reduction is presented,...

• Automatic evaluation of sound separation quality

  Publikacja

  • M. Dziubiński

  - Rok 2005

  W publikacji tej opisano problem oceny efektywności algorytmów separacji dźwięków muzycznych. Standardowa procedure służąca do takiej oceny nie istnieje. Najbardziej uzasadnionym podejściem wydają się być odsłuchowe testy subiektywne. Niemniej, aby taka ocena była wartościowa, niezbędna jest porządna walidacja statystyczna wyników, co oznacza iż grupa ekspertów powinna być duża oraz właściwości akustyczne pomieszczenia. Ponadto...
