METHOD AND DEVICE FOR PROCESSING AUDIO DATA IN AN AMBISONIC CONTEXT

摘要

The invention relates to the processing of off-air signals in order to obtain ambisonic components. Said operation (1), so-called matrixing, is carried out by applying a matrix to said off-air signals that is corrected in order to maintain an orthonormality between the harmonic ambisonics, and then to minimise an aliasing effect of the ambisonic components on components being estimated.
