Abstract
An example approach for navigation is provided with an apparatus comprising: a navigation processor configured to generate at least one navigation command; and an audio processor configured to determine at least one directional audio parameter so as to provide a direction, the at least one directional audio parameter being based on the navigation command and further configured to process at least one audio signal based on the at least one directional audio parameter such that a virtual sound image of a navigation routing is generated based on the processed at least one audio signal.
Claims20
A method comprising:
- generating, for a navigation system coupled to at least two speakers, at least one navigation command for a navigation routing to a target point, wherein the at least one navigation command comprises at least one keyword, where the at least one keyword comprises at least one audio signal or a representation of at least one audio signal;
- determining at least one directional audio parameter, where the at least one directional audio parameter provides at least one sound direction that is different from a reference direction, where at least part of a remainder of the at least one navigation command is configured to be perceived from the reference direction during rendering, where the at least one sound direction is configured to be applied for rendering of the at least one keyword, where the at least one directional audio parameter is based on a traveling direction of the navigation routing to the target point;
- processing at least the at least one keyword based on the at least one directional audio parameter such that at least one virtual sound image of the traveling direction of the navigation routing is generated based on the processed at least one keyword,
- wherein the at least one directional audio parameter comprises at least one audio processing cue and is based on the at least one navigation command, and
- wherein the at least one virtual sound image is perceived as coming from the traveling direction of the navigation routing.

A apparatus comprising:
- at least one processor;
- and
- at least one non-transitory memory and computer program code;
- the at least one non-transitory memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform:
- generate, for a navigation system coupled to at least two speakers, at least one navigation command for a navigation routing to a target point, wherein the at least one navigation command comprises at least one keyword, where the at least one keyword comprises at least one audio signal or a representation of at least one audio signal;
- determine at least one directional audio parameter, where the at least one directional audio parameter provides at least one sound direction that is different from a reference direction, where at least part of a remainder of the at least one navigation command is configured to be perceived from the reference direction during rendering, where the at least one sound direction is configured to be applied for rendering of the at least one keyword, where the at least one directional audio parameter is based on a traveling direction of the navigation routing to the target point;
- process at least the at least one keyword based on the at least one directional audio parameter such that at least one virtual sound image of the traveling direction of the navigation routing is generated based on the processed at least one keyword,
- wherein the at least one directional audio parameter comprises at least one audio processing cue and is based on the at least one navigation command, and
- wherein the at least one virtual sound image is perceived as coming from the traveling direction of the navigation routing.

A non-transitory computer-readable medium comprising program instructions stored thereon which, when executed with at least one processor, cause the at least one processor to:
- generate, for a navigation system coupled to at least two speakers, at least one navigation command for a navigation routing to a target point, wherein the at least one navigation command comprises at least one keyword, where the at least one keyword comprises at least one audio signal or a representation of at least one audio signal;
- determine at least one directional audio parameter, where the at least one directional audio parameter provides at least one sound direction that is different from a reference direction, where at least part of a remainder of the at least one navigation command is configured to be perceived from the reference direction during rendering, where the at least one sound direction is configured to be applied for rendering of the at least one keyword, where the at least one directional audio parameter is based on a traveling direction of the navigation routing to the target point;
- process at least the at least one keyword based on the at least one directional audio parameter such that at least one virtual sound image of the traveling direction of the navigation routing is generated based on the processed at least one keyword,
- wherein the at least one directional audio parameter comprises at least one audio processing cue and is based on the at least one navigation command, and
- wherein the at least one virtual sound image is perceived as coming from the traveling direction of the navigation routing.
