Plogue bidule stereo to 5.11/7/2024 After the review of the literature an investigation is introduced. ![]() Source width in music recording and production practice in stereo and surround as well as in ambisonics and wave field synthesis are addressed. In this chapter perceived source width in psychoacoustics and apparent source width in room acoustical research are revisited. It is influenced by the sound radiation characteristics of the source and by the room acoustics and restricted by masking and by localization accuracy. In contrast to that, perceived source width is a matter of psychological organization of sound. Source width of musical instruments, measured in degrees, is a matter of source extent and the distance of the observer. Finally, a glimpse into the extension of the proposed method to create three-dimensional measurement-based Ambisonic reverberation is discussed. Experimental results are provided and show good agreement with the theory. Practical considerations such as Ambisonic room response estimation and robustness of the method are investigated. Method is efficient and can reduce the reproduction error to -14 dB in the reconstruction area defined in free field. Simulation results are presented in frequency, space, and temporal domains over a wide-range of frequencies. A crossover and cross-order method is proposed to circumvent this problem and to reduce the amount of necessary regularization. ![]() Their design requires the inversion of a matrix which can be ill-conditioned at low frequencies and for higher Ambisonic orders. The compensation filters are designed to operate in the spherical harmonics domain, prior to the decoding step. A multichannel room equalization method for Ambisonic playback systems is proposed. This paper investigates the compensation of room reflections based on Ambisonics.
