A system and a corresponding method for assisting selective hearing are provided. The system includes a detector for detecting an audio source signal portion of one or more audio sources by using at least two received microphone signals of a hearing environment. In addition, the system includes a position determiner for allocating position information to each of the one or more audio sources. In addition, the system includes an audio type classifier for assigning an audio source signal type to the audio source signal portion of each of the one or more audio sources. In addition, the system includes a signal portion modifier for varying the audio source signal portion of at least one audio source of the one or more audio sources depending on the audio signal type of the audio source signal portion of the at least one audio source so as to obtain a modified audio signal portion of the at least one audio source. In addition, the system includes a signal generator.

System and method for assisting selective hearing

A mixing console () for processing at least a first and a second source signal and for providing a mixed audio signal comprises an audio signal generator () for providing an audio signal () for a virtual listening position () within a space (), in which an acoustic scene is recorded by at least a first microphone () at a first known position within the space () as the first source signal () and by at least a second microphone () at a second known position within the space () as the second source signal (). The audio signal generator () comprises an input interface () configured to receive the first source signal () recorded by the first microphone () and the second source signal () recorded by the second microphone (), and a geometry processor () configured to determine a first piece of geometry information () based on the first position and the virtual listening position () and a second piece of geometry information () based on the second position and the virtual listening position (). A signal generator () for providing the audio signal () is configured to combine at least the first source signal () and the second source signal () according to a combination rule using the first piece of geometry information () and the second piece of geometry information ().
