Frequently we deal with analog data from noisy acoustic measurements which need a preprocessing prior to the extraction of the information embedded. Data deterioration may be due to several reasons, for example: data recording on obsolete and technological poorsupport; bad signal conditioning (poor signal-to-noise ratio, non linearity and/or timevariance of the system under test). Sometimes information to be extracted from data is not conventional so it needs a dedicated processing. In this paper a novel audio data processing method from the autors experience in ancient open-air theatres research is shown.
