Classification: CPC G  H | IPC G  H

Claim 0:
1. A method comprising:
receiving a data, wherein the data describes boundaries of a first room and a sound source position for a first sound source in the first room;
determining a at least one virtual sound source as a mirrored sound source by performing sound source mirroring of at least one previous sound source,
wherein the previous sound source had been determined previously,
wherein the determining of the at least one virtual sound source for each source room of a at least one source room comprises:
determining at least one mirror boundary for the source room;
determining a mirror room for each mirror boundary of at least one of mirror boundary by mirroring the source room around the mirror boundary,
determining a mirror sound source by mirroring a source sound source around the mirror boundary,
wherein the source sound source is a mirror sound source of the source room,
wherein the mirroring has a direction of mirroring from the source room to the mirror room;

wherein the determining of the at least one mirror boundary comprises selecting boundaries of the source room in accordance with a selection criterion,
wherein the selection criteria comprise a requirement that a candidate boundary of the source room is comprised within the at least one mirror boundary,
wherein a first direction of mirroring for the candidate boundary is not in an opposite direction of a direction of mirroring for any previous mirroring leading to the source room,
wherein the first direction is not in an excluded direction,
wherein the excluded direction is dependent on a boundary of the first room around which mirroring leading to the source room was performed,
wherein the first direction is not in a same direction as any direction of mirroring for any previous mirroring leading to the source room except for a direction of mirroring of a mirroring generating the source room in an immediately previous operation.
