Abstract:
From an HOA signal representation (c(t)) of a sound field having an order of N and a number 0=(N+1) 2  of coefficient sequences a mezzanine HOA signal representation (w MEZZ (t)) is generated that consists of an arbitrary number I<0 of virtual loudspeaker signals W MEZZ1 (t), W MEZZ,2 (t), . . . , W MEZZ,I (t). 0 directions are computed which are nearly uniformly distributed on the unit sphere. The mode vectors with respect to these directions are linearly weighted for constructing a matrix, of which the pseudo-inverse is used for multiplying the HOA signal representation (c(t)) in order to form (11) the mezzanine HOA signal representation (W MEZZ (t)).
