Procedure for acquiring audio signals and audio acquisition system thereof

摘要

Procedure for acquiring audio signals, in which a probe microphone (11) provided with a decápsulas plurality microphonic (B) detects a plurality of audio signals, and wherein said signals audiodetectadas are combined to obtain a signal a virtual microphone (207), wherein said signal of a virtual microphone is generated based on a data characteristic sensor (206) measured during a characterization step of the probe, in which the signals detected by cadacápsula microphonic measured (B) after a signal corresponding default test, in which each cambioen parameters of the virtual microphone is followed by a new generation of filters (203) puedenutilizarse to filter the signals received by said plurality of capsules and generate a new audio signal dedicho virtual microphone, wherein, when said virtual microphone parameters are changed to switch from one corresponding to a first filter, a second virtual microphone, virtual primermicrófono following occur: - a second filter corresponding to the second virtual microphone is calculated; - an ordered set of filters transaction is calculated, wherein each of said filters transaccióncomprende corresponding submatrices to submatrices of said first filter or said second filter, wherein the number of submatrices of the second filter of said filter transaction is Numberof submatrices greater than the second filter a filter above transaction, and wherein the number of submatrices of the first filter of said filter transaction is less than the submatrices Numberof the first filter a filter previous transaction; - the signal captured by said capsules (B) signal is filtered through said filter in the order transaction dedicho filter set transaction; - after the last transaction filter of said assembly, the captured by said capsules (B) signal is filtered using said second filter.
