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 (wMEZZ(t)) is generated that consists of an arbitrary number I < 0 of virtual loudspeaker signals wMEZZ1(t), wMEZZ,2(t),..., wMEZZ,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 (wME.ZZ(t)). |
