According to an example aspect of the present invention, there is provided A controllable loudspeaker, the loudspeaker comprising a speaker element and a digital signal processor comprising at least one processing core and at least one memory including computer program code, the at least one memory and the computer program code being configured to receive a multicasted control signal, alter the behavior of the loudspeaker in response to the said control signal, wherein the altering of the behavior comprises applying settings stored in the memory of the digital signal processor of the loudspeaker.

Loudspeaker and loudspeaker control system

In accordance with an example aspect of the present invention, an apparatus is provided, the apparatus comprising at least one processing core, at least one memory including computer program code, the at least one memory and the computer program code being configured to, with the at least one processing core, cause the apparatus at least to derive, from first digital information describing a system impulse response caused by a loudspeaker to a first location in a first room, second digital information describing a cancelling impulse response, determine, for samples comprised in the second digital information, at least one of a delay value describing how much the samples are to be shifted in time and a gain factor describing how much the samples' magnitude is to be adjusted, so that an energy associated with a sum of the system impulse response and the cancelling impulse response is reduced, and employ the determined at least one of the delay value and the gain factor to generate a cancelling signal, and to add the cancelling signal to a signal provided to the loudspeaker.

Control of acoustic modes in a room

According to an exemplary aspect of the present invention, there is provided an apparatus comprising: at least one loudspeaker element, at least one processing core, at least one memory including computer program code, the at least one memory and the computer program configured to, with the at least one processing core, cause the apparatus to produce sound via the loudspeaker element, wherein the at least one processing core is configured to adjust the sound according to criteria stored in the at least one memory, wherein the criteria comprise a wide bandwidth roll-off using at least one parametric shelving filter.

Personal sound character profiler

According to an example aspect of the present invention, an apparatus is provided comprising at least one processing core and at least one memory including computer program code, the at least one memory and the computer program code being configured to, with the at least one processing core, cause the apparatus at least to present a graphical user interface comprising a spatial representation and at least one element, the element being associated with at least one specific physical loudspeaker, and receive input concerning moving of the at least one element within the spatial representation, activate a sensory signal in a physical loudspeaker associated with the first element, determine a location in the spatial representation where the first element is moved to, and based at least in part on the determined location, assign a name to at least the first element and the physical loudspeaker associated with the first element.

Loudspeaker control

The present publication describes a calibration method and apparatus, in which an electrical calibration signal is formed, an audio signal is formed in the loudspeaker from the calibration signal, the response of the audio signal is measured and analyzed, and the system is adjusted on the basis of the measurement results. The calibration signal is formed in the loudspeaker in such a way that it is essentially a sinusoidal signal, the frequency of which scans at least substantially through the entire audio frequency range.

Calibration method and device in an audio system

A method and apparatus in a sound-reproduction system, in which method an electrical calibration signal is formed, an audio signal is formed in the loudspeaker from the calibration signal, the response of the audio signal is measured and analysed, and the loudspeaker system is adjusted on the basis of the measurement results. The operator is permitted to made additional alterations to the settings of the loudspeaker system on the basis of the measurement performed, the effects of the alterations are calculated and displayed to the operator without additional measurements, and the additional settings are implemented in real time in the loudspeaker system.
