Abstract
The paper describes options to use a single point surround microphone to determine a direction of the sound source localization (SSL). A “soundfield” microphone with four transducers (capsules) characterized by cardioid responses. A unique mechanical design of the transducer results in its omnidirectional response. The microphone enables 3D sound acquisition in so called A-format. Upon further processing of signal it is possible to determine e.g. a direction of a sound source within space. The conducted experiments prove that a simple calculation algorithm is in particular feasible for a real time operation, and application of the soundfield microphone significantly simplifies mechanical design of the SSL system.
Scientific work financed by the Ministry of Higher Education and Science (Poland) from funds for the science in years 2009 - 2010, as a research project No. N N505 364336.
