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)).

Claim (Index 19):
The method of  claim 17 , further comprising determining a reduced-order version c R (t) for an initial order reduction of c(t), for which N is replaced by N R , 0 is replaced by 0 R , and S n  is replaced by S n,R , I<0 R , 0 R =(N R +1) 2 , wherein N R  is a reduced order smaller than order N, such that the resulting number 0 R  of coefficient sequences is the smallest integer number square that is greater than the number I,\n and wherein w MEZZ (t)=V + \u00b7c R (t).
