Ambisonic is a three-dimensional reproduction system which has been widely used for more than four decades. Its wide use is due to the robust reconstruction of the sound field that allows the generation of immersive environments. This thesis presents the evaluation of different methodologies for 3 cases of decoding based on different types of propagation and sound sources. Where the near field is included The analysis of these models contemplate the amount of energy required by the system for the reconstruction of the sound field, errors with respect to the theoretical sound field as: amplitude error, normalized amplitude error and phase error. Finally, the analysis of the near-field filters in the time and frequency domain is performed. The numerical simulations show that it is indeed possible to compensate the effect of near field produced by the monopoles at the expense of a great energy generated by the system |
