Claim 4:
5. Apparatus of claim 1,
wherein the input signal comprises the mono signal, and wherein the low-order components generator is configured to generate a zero order Ambisonics signal by taking or copying the mono signal, or
wherein the input signal comprises at least two channels, and wherein the low-order components generator is configured to generate a zero order Ambisonics signal by adding the two channels and to generate a first order Ambisonics signal based on a difference of the two channels, or
wherein the input signal comprises a first order Ambisonics signal with three or four channels, and wherein the low-order components generator is configured to generate a first order Ambisonics signal by taking or copying the three or four channels of the input signal, or
wherein the input signal comprises an A-format signal comprising four channels, and wherein the low-order components generator is configured to calculate a first order Ambisonics signal by performing a weighted linear combination of the four channels.
