Apparatus and method for generating a plurality of audio channels

A method for generating a plurality of audio channels for a first speaker setup, comprising:

• determining a position of an imaginary speaker not comprised in the first speaker setup and acquiring a second speaker setup comprising the imaginary speaker;
• calculating an energy distribution from the imaginary speaker to the other speakers in the second speaker setup;
• repeating the energy distribution and acquiring a downmix information for a downmix from the second speaker setup to the first speaker setup;
• and
• generating the plurality of audio channels using the downmix information.

A non-transitory storage medium having stored thereon a computer program comprising program code for performing a method for generating a plurality of audio channels for a first speaker setup, comprising:

• determining a position of an imaginary speaker not comprised in the first speaker setup and acquiring a second speaker psetup comprising the imaginary speaker;
• calculating an energy distribution from the imaginary speaker to the other speakers in the second speaker setup;
• repeating the energy distribution and acquiring a downmix information for a downmix from the second speaker setup to the first speaker setup;
• and
• generating the plurality of audio channels using the downmix information, when said computer program runs on a computer.
