Abstract:
For converting a channel-based 3D audio signal to a higher-order Ambisonics HOA audio signal, the channel-based 3D audio signal is transformed ( 21 ) from time domain to frequency domain. A primary ambient decomposition ( 22 ) is carried out for three-channel triplets of blocks of the domain channel-based 3D audio signal, wherein directional signals and ambient signals are provided ( 37 ) for each triplet. From the directional signals directional information of a total directional signal for each triple is derived ( 23 ). That total directional signal is HOA encoded ( 25 ) according to the derived directions, and ambient signals are HOA encoded ( 24 ) according to channel positions. The HOA coefficients of the HOA encoded directional signal and the HOA coefficients of the HOA encoded ambient signal are superimposed ( 27 ) in order to obtain a HOA coefficients signal for the channel-based 3D audio signal, followed by a transformation ( 26 ) into time domain.

Claim (Index 8):
The method of  claim 1 , wherein based on the decomposition order, said primary ambient decomposition is carried out for individual triplets, thereby delivering directional and ambient signals of three channels, and wherein three directional signals are combined to a total directional signal according to the principle of summing localisation, while the directions are derived by means of panning laws.
