METHOD, COMPUTER PROGRAM AND APPARATUS FOR PROCESSING AUDIO SIGNALS

An apparatus comprising at least one processor and at least one memory including computer program code. The at least one memory and the computer program code is configured to, with the at least one processor, cause the apparatus at least to perform filtering at least two audio signals to generate at least two groups of audio components per audio signal, determining a difference between the at least two audio signals for each group of audio components, and generating a further audio signal by selectively combining the at least two audio signals for each group of audio components dependent on the difference between the at least two audio signals for each group of audio components.
