Definitions

  • the present invention relates to the field of audio, audio signal processing, and audio applications. More specifically, the invention provides a method and a device which allows a user to easily set up an audio processing to fit the audio properties for optimal sound quality with a specific audio output device.
  • Many multi-purpose devices e.g. smartphones and the like, have the properties to form a centre for various types of audio playback. This means that the device is used with different types of audio reproduction devices which have very different electro-acoustical properties. Examples of different audio reproduction devices to be used e.g. with a smartphone are: in-ear earphones, small portable loudspeakers, mid-sized hi-fi docking station, hi-fi system with floor standing loudspeakers. Audio playback from e.g. a smartphone to these devices with optimum sound quality requires significantly different audio outputs from the smartphone.
  • In-ear earphones may be used outdoors and thus also in noisy environment, why a limited dynamic range is preferred, and further a spectral equalizing to compensate for a non-linear frequency response can be required.
  • Small portable loudspeakers may profit from a bass enhancement combined with a sharp cut off below a lower limit frequency, and possibly the user may prefer to switch on a spatial enhancement or virtual surround feature with such small closely spaced stereo loudspeakers.
  • streaming to a high-end hi-fi system normally it is desired to have a full dynamic range and also a full frequency range without equalizing.
  • the invention provides a device comprising
  • Such a device e.g. in the form of a handheld device such as a smartphone, is advantageous, since it allows the user to connect acoustically different types of audio output devices to the device for music or speech reproduction.
  • Such output device can be various types of headphones, small portable loudspeakers or large hi-fi loudspeaker, and the device according to the invention is capable of adapting its audio processing such that an optimal sound quality can be obtained for the selected device in an easy manner with a minimum of user involvement.
  • the prestored settings can include a set of default settings from the manufacturer of the device which may include standard predefined parameters, e.g. a standard equalizing function, which is found to provide a good result with a typical type of reproduction device, e.g. in-ear earphones.
  • standard predefined parameters e.g. a standard equalizing function
  • the invention also allows a more specific approach, where a product specific prestored audio processing setting can be selected, thus allowing e.g. a more optimal equalizing for a specific in-ear earphone, or the like.
  • the user interface may comprise a graphical interface programmend such that the user is presented by a selection of icons on the display of the device, where each icon represents an audio reproduction device type using a symbol and/or text.
  • each icon represents an audio reproduction device type using a symbol and/or text.
  • the user can ensure, by a single touch on the icon corresponding to the connected reproduction device, that an audio processing is selected to match the reproduction device for optimal sound quality.
  • the detector By means of the detector, it is ensured that the user request can be automatically triggered, thus the user is automatically requested to select the relevant option when connecting an audio reproduction device. This serve to ensure that optimum sound quality can be provided with a minimum of user involvement, and further it is ensured that the right volume is set up, thus preventing a too high level being applied which may be annoying or even dangerous for the user's hearing.
  • the user interface may be programmed to allow the user to skip the selection request popping up every time the reproduction device is connected, and the user interface may further be user-programmable so as to allow the user to limit the possible selection types to the two or three most frequently used reproduction devices.
  • the device may be programmed to allow a ranking of the reproduction device types to be displayed to the user, such as displaying the types in order of how frequently the user selects them, e.g. with the most frequently selected type presented on top of other types, or the most frequently selected type(s) may be presented with a larger icon than less frequently selected types etc., so as to facilitate the choice of the user.
  • the user may prestore one or more preferred audio parameters together with a general audio setting for the actucal reproduction device, so as to adapt the resulting sound to the user's prefererences.
  • the invention can also be used to match more product specific electro-acoustical properties based on measurements and corresponding prestored audio processing parameters for a specific product. This can be obtained e.g. by downloading audio processing parameters for one or more specific products, e.g. via the internet or another wireless network, if the user wants to apply a product specific processing.
  • an audio reproduction device may be sold with a QR code on its package which the user can scan in order to link to an internet address with the specific audio processing settings for the audio reproduction device inside the package, e.g. when purchasing a new reproduction device, such as an in-ear headphone or the like.
  • the QR code Either, by scanning the QR code, the corresponding specific audio processing settings are automatically downloaded in the device, e.g. mobile phone, and/or also automatically applied, or the user is asked to initiate downloading/applying the settings. This allows the user to get easy access to the desired audio processing settings for the specific reproduction device, and thus provides an easy way of obtaining an optimal sound quality by merely scanning a QR code.
  • the device can by no means automatically detect the type of reproduction device connected, since this is merely a cable with a socket.
  • wireless connections e.g. Bluetooth
  • the user interface may be adapted to request the user input about the connected type of reproduction device after or at the same time as informing the user that a connection has been established, but before audio streaming to the connected reproduction device is initiated.
  • the user interface comprises a graphical user interface using a display of the device.
  • an audio interface with speech input/output may be used to request the input from the user.
  • the plurality of preselected audio reproduction device types may be graphically presented to the user as respective different icons, e.g. icons with symbols allowing identification of each type without text, or text may be used instead or in addition.
  • the user may be allowed to alter the user interface to the actual need, e.g. limiting the options to select from in order to limit the options to the types of reproduction devices the user normally chooses from.
  • the plurality of preselected audio reproduction device types may comprise a plurality of the types: over-ear headphone, earphone, in-ear earphone, one-ear headphone, portable audio device, hi-fi device, and TV set.
  • the user interface may be programmed to have a main menu where the user can select a type of reproduction device, e.g. 3-10 types, and after this selection, if the user desires so, one or more sub menus may be used to allow a more detailed or even product specific input which is used to select a more specific prestored audio processing setting which can provide an even higher sound quality.
  • a product specific processing can include spectral filters with compensation of rather narrow peaks and dips in specific earphones, and further this allows matching of volume setting by taking into account product specitic electro-acoustic sensitivities.
  • the user interface may be arranged to request the user to enter one from a list of a plurality of specific audio reproduction devices belonging to the entered audio reproduction device type, and to select a specific audio processing setting or to modify the selected prestored audio processing setting in accordance with the entered specific audio reproduction device. This allows a better individual matching of specific audio processing parameters to fit to the electro-acoustical design of a specific product.
  • the device may be programmed to update the list of specific audio reproduction devices, such as by automatically downloading data for new specific audio reproduction device via the internet.
  • the device can be kept up to date with new audio reproduction products which may have specific individual audio processing parameters assigned thereto for optimal acoustic performance.
  • the prestored audio processing settings may be designed to match acoustical properties of the respective audio reproduction device types. As already mentioned, this may be in the form of rather general matching filters or other processing parameters which provides good performance with a generic type of audio reproduction device. It may also be specific filtering parameters to fit a specific product. Still further, the settings may include user designed properties or user selected properties according to preferences - e.g. it can be part of a prestored setting that surround sound should be "on” when the audio reproduction type "in-ear earphones" is selected.
  • the prestored audio processing settings may comprise parameters affecting audio processing with respect to at least one of: spectral filtering, dynamic limiting, dynamic enhancement, spatial enhancement, and volume adjustment.
  • parameters affecting audio processing with respect to at least one of: spectral filtering, dynamic limiting, dynamic enhancement, spatial enhancement, and volume adjustment.
