Definitions

  • the present invention relates to a method and system for dynamic reconfiguring an audio reproduction system comprising two or more sound channels.
  • the premises of the reconfiguring are being based on the position of one or more listeners and the one or more sound channels in the reproduction system.
  • the feature obtained is a sound distribution into individual zones of sound fields.
  • the invention includes digital signal processing, sound transducers, filters and amplifier configurations to be applied in surround sound systems and traditional stereophonic system, and to be applied in any domain like a home, in a vehicle, in a boat, in an airplane, in an office or in any other private or public domain, this being airports, shopping centres, sports arenas and theatres, i.e. in a PA system.
  • Document US2004/0240676 A1 describes that a wide frequency range signal from a test sound source is reproduced successively by a plurality of speakers, and the reproduced sound is detected by a plurality of microphones, after which the frequency characteristics thereof are obtained at FFTs, while obtaining the frequency characteristics of the wide frequency range signal at an FFT.
  • a high frequency range level is normalized with a low frequency range level, and a determination section compares the normalized value with a reference value stored in a reference value storage section to determine the number and positions of people in the sound field.
  • the transfer functions between the speakers and the microphones are calculated at transfer function calculators, and impulse responses are obtained at IFFTs, after which a reverberation time calculator calculates the reverberation time based on the impulse responses.
  • An audio signal is adjusted based on the results obtained from the determination section and the reverberation time calculator, whereby it is possibly to optimize the audio reproduction according to changes in the sound field.
  • test signals are generated and received. The received (distorted) signal is then used in order to adjust the output of the of the sound reproduction system (audio tuning system).
  • the individual sound channels incorporating one or more loudspeaker modules must be calibrated and adjusted individually and according to the number of persons in the car, and their position in the space e.g. their seated positions.
  • This principle may be applied in any type of room like airplanes, boats, theatres, arenas, and shopping centres and alike.
  • the invention discloses a surround sound system where different sound settings may be enabled via digital signal processing means controlling the individual sound channels parameters e.g. the equalization (filters), the delay, the gain (amplification).
  • the premise for the control is based upon the listener's position in the listening room/space.
  • the control and sound setting may work in a contextual mode of operation to accommodate for:
  • the invention discloses a solution that in an automatically mode of operation may fulfil the stated requirements and solve the related technical problems.
  • the invention may be implemented in different embodiments.
  • An example not claimed of the reconfiguring procedure may be implemented as:
  • the reconfiguring procedure is implemented as:
  • a method for dynamic and automatic reconfiguring an audio reproduction system comprising two or more sound channels comprises the set of features defined in independent claim 1.
  • the fundamental goal of the invention is to enhance the perceived sound quality seen from a listener prospective. Regardless of the physical position of the loudspeakers, a virtual sound field may be generated and directed so it appears to be anywhere the listener may desire. This is obtained by adjusting the gain, the delay and the equalization parameters of the individual sound channels in a multichannel sound system.
  • the reconfiguring process validates the position of the one or more users, and/or functional premises and/or context related premises and or content related premises as part of the reconfiguring of the one or more sound channels that constitutes the configured loudspeaker system, and where the validation prioritizes the position of one or more listeners.
  • miscellaneous features may be offered and controlled automatically and/or commanded by the user. The features may be used individually and/or mixed in a way that accommodates the user's demands.
  • a predefined combination of sound settings per channel and the functional options supports the processing. Examples of functional options are:
  • the reconfiguring process is provided as one or more algorithms to provide the calculation of each of the values of the sound channel adjustment variables.
  • the reconfiguring process is provided as a table with relations provided to be accessed by the digital signal processor to provide each of the values of the sound channel adjustment with variables.
  • the saved attributes and key parameters are loaded into the reconfiguring means supported by electronic means, means that is connected wirelessly or connected by wire to the audio reproduction system.
  • the reconfiguring process provides the settings of the sound parameters; gain, equalization and delay for one sound channel, to be applied in one sound field zone related to the physical position of first group of people including one or more listeners.
  • the reconfiguring process provides the settings of the sound parameters; gain, equalization and delay for one sound channel, to be applied in one sound field zone related to the physical position of one or more other groups of people including one or more listeners.
  • a listener position is detected via standard sensor means like switches or infrared detectors or strain gauges or temperature sensitive detectors.
  • the configuring process is to be automatically executed and/or controlled by the audio amplifier means, including a digital signal processor, which drives the loudspeaker system.
  • the reconfiguring means is embedded into an audio reproduction system.
  • the reconfiguring is controlled via a table mapping the mode of operation to adjustment parameters for each speaker in every channel or just relevant channels.
  • the adjustment parameters are e.g. but not limited to: equalization, delay and gain.
  • the table may be represented as one or more data set as most appropriate to the digital controller unit.
  • one data set may contain the relations among:
  • Another data set may contain the functional/mode related information like:
  • This table concept is considered to be a data driven control systems, and enables for easy updates of the functional behaviour of a specific system simply by loading alternative data set into the controller.
  • the invention includes a constraint Solver, which comprises a table with digital data representing the constraints of the passenger(s) position(s) and related acoustical adjustment, attributes and corresponding variable values.
  • the constraint solver processing enables an arbitrary access mode to information with no order of sequences required. This is an important advantage over prior art tree-like programming structure, where the starting point is given by the root of the tree. Especially, when finding ways from nodes within the tree-like program to a specific target location in the tree, it may be obscure with regard to which way to chose, whether backwards or forwards, and the final solution may be a new start from the root.
  • the product configuration domain table is organized as relations among variables in the general mathematical notation of 'Disjunctive Form':
  • AttribVariable 1.1 may be defining a passenger seat position, AttribVariable 1.1 a speaker transducer unit, AttribVariable 1.3 a speaker system/subsystem and AttribVariable 1.n gain value for the transducer unit.
  • AttribVariable 2.n may be a reference to another table.
  • multidimensional has to be understood as a contrast to a tree-like programming structure, which is two-dimensional.
  • the product configuration function proceeds by finding the result of the interrogation in the set of allowed and possible combinations in one or more Configuration Constraint Tables. According to definitions made in the configuration constraint tables, the result might be:
  • Alternative configurations may be evaluated by the constraint solver, the alternatives being one or more of the defined set of legal combination in the constraint table.
  • the example illustrates alternative solutions for x, y when y is given: The: If x Then y may be represented as x -> y
  • the x -> y has the legal combinations of x, y: x y 0 0 0 1 1 1
  • Table entries in a constraint table may be combined into legal/illegal combination such that all the well known logical operators known from the Boolean algebra will be included as required.

  • Means for down regulation may be as simple as adjustment of a resistive means serial connected to the loudspeaker module.
  • the sound delay among channels must be controlled.
  • the delay (4) is controlled individually per sound channel.
