Method for reproducing an audio recording with the simulation of the acoustic characteristics of the recording condition
Abstract:
The method relates to audio recording reproduction. The method involves testing the features of a three-dimensional sound field using a dual or multi-channel system of spatially distributed channels, transmitting audio signals, and recording the responses in order to determine the differences between the influence of the natural acoustical properties of a room and the influence of the mutual spatial arrangement of audio sources and audio receivers on the characteristics of the sound field. Determining the differences between the features of the three-dimensional sound fields at different recording and reproduction conditions in accordance with this method makes it possible to adjust the parametric data of the tonal characteristics when reproducing an audio recording in order to produce a sound field identical to the sound field of the recording.
