Audio data processing method for e.g. documentary recording, involves encoding sound signals, and applying spatial component amplitude attenuation in frequency range defined by component order and distance between source and reference point
The method involves encoding signals, representing a sound propagating in a three-dimensional space, from a source (S) located at a distance (rho ) from a reference point to obtain a representation of sound by spatial components. Attenuation of amplitude of the components is applied in a range from low frequency to high frequency, defined according to order of the components and the distance, to correct a near field effect.
