Audio reproduction systems include a plurality of loudspeakers that are actuated in accordance with a multi-channel audio format. The loudspeakers can be configuratable by way of a network interface The loudspeakers are registered on the network. A method for automatic configuration of an audio reproduction system includes automatically determining that all loudspeakers are connected to the network, determining the number of loudspeakers which are disposed in the same room and which are part of the loudspeaker arrangement, automatically generating a representation of a virtual loudspeaker arrangement on a display according to the determined number, and sequentially, for each loudspeaker belonging to the loudspeaker arrangement, as an actual loudspeaker, generating a signal by the actual loudspeaker, receiving a user input characterizing a virtual loudspeaker, assigning the position of the characterized virtual loudspeaker to the actual loudspeakers and configuring audio signal processing for the actual loudspeaker according to its assigned position.

Method and device for automatic configuration of an audio output system

Loudspeaker systems, which for technical reasons are not suitable for emitting strong bass signals, can use so-called virtual bass systems. Therein, low frequencies are replaced by their harmonics. However, virtual bass cannot always adequately replace real bass, such that tonal discrepancies may result. Methods and systems are disclosed to improve the bass reproduction of virtual bass by mixing the generated harmonics with a reduced original bass component of the input audio signal. The mixing ratio of this blend can be variable and can be determined automatically. For example, the mixing ratio can change when a level threshold is exceeded, when a temperature rises above/drops below a threshold, a calorimetric threshold is exceeded, or at fixed times of day.

Method and apparatus for processing audio signals

A control unit for an audio system including a subwoofer and at least one further loudspeaker. Type information is recorded via the at least one connected loudspeaker, and a configurable filter for the at least one connected loudspeaker is configured by means of appurtenant configuration information from a memory. The configurable filter is configured so that a base phase management is provided for the transition frequency range between the subwoofer and the at least one connected loudspeaker so that the phase of the sound signals of the subwoofer is matched to the phase of the sound signals of the at least one connected loudspeaker.
