Method for playing back the sound of a digital audio signal
Abstract:
A method for playing back the sound of a digital audio signal comprising an oversampling step consisting of producing, from a signal sampled at a frequency F, a signal sampled at a frequency N×F, where N corresponds to an integer greater than 1, then of applying convolution processing to a first digital file sampled at a frequency N×F corresponding to the acquisition of the soundscape of a reference sound space, a second digital file sampled at a frequency N×F corresponding to the acquisition of the noise footprint of a piece of reference playback equipment, a third digital file sampled at a frequency N×F corresponding to the acquisition of the noise footprint of an equalizer and a fourth file corresponding to said oversampled audio file, the resulting digital packets then undergoing digital conversion processing at a sampling frequency F/M corresponding to the working frequency of the listening equipment.
