Abstract

The method involves compressing several audio signals with a conventional compression technique by combining sound sources similar to a sound field and selecting compression factors so that the maximum permitted data rate is not exceeded. Information is added to the combined sound sources regarding the type of source and the object position with respect to the observer <??>AN Independent claim is also included for the following: an arrangement for implementing the inventive method.
