1. An audio system comprising:
- a position sensor providing current position location information;
a database for storing a plurality of data records wherein each data item is associated with at least location information and audibly playable information;
means for querying said database to find one or more data records matching search criteria, the search criteria including at least position information associated with the current position location information;
an audio processing unit for retrieving the audibly playable information associated with one or more data records found in said database, said audio processing unit generating a spatialized audio cue for at least selected ones of said one or more data records in said database as a function of at least the current position location information provided by said position sensor and the position information associated with the stored data record, the current position information being updated during the generation of said spatialized audio cue and the audio processing unit changing spatialization of the spatialized audio cue in response to changes of the current position information as said spatialized audio cue is generated; and
audio components for audibly reproducing said spatialized audio cue.

15. A method for enabling location based audio playback comprising:
-
storing a plurality of audio clips and associated location information; receiving real-time position data of a vehicle, including vehicular orientation data; selecting a subset of said plurality of audio clips based on at least said real-time position data; and providing spatialized audio in said vehicle for an audio clip in said subset of said plurality of audio clips through the analysis of said real-time position data of a vehicle, including said vehicular orientation data, relative to the location information associated with said audio clip, the spatialized audio having a perceived orientation within said vehicle which coincides with the location information associated with the audio clip and the perceived orientation of the spatialized audio changing in response to changes of said real-time position data while the spatialized audio for said audio clip is being provided in said vehicle. - View Dependent Claims (16, 17, 18)

19. A method for providing audio information in a vehicle regarding external landmarks comprising:
-
receiving an information signal, said information signal comprising at least a current orientation of the vehicle, said information signal being updated as the vehicle moves relative to said external landmarks; producing a spatialized audio signal based on said information signal, wherein said spatialized audio is produced having a spatial orientation within said vehicle which spatially coincides with an associated landmark; and wherein the spatial orientation of the spatialized audio signal relative to the associated landmark is updated in response to updates of the information signal while the spatialized audio based on said information signal is being produced within said vehicle. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)

27. A method for providing audio information in a vehicle regarding external landmarks comprising:
-
determining a current location of the vehicle; retrieving from a database information regarding landmarks located in a vicinity of said vehicle based at least in part on the current location of the vehicle; and producing a spatialized audio signal based on the information regarding landmarks retrieved from said database as the vehicle approaches a retrieved landmark, wherein spatialized audio is produced in said vehicle using said spatialized audio signal, the spatialized audio being spatially oriented in a real time fashion relative to a position of the retrieved landmark located externally of the vehicle (i) as the vehicle approaches said retrieved landmark and (ii) while said spatialized audio signal is being produced in said vehicle. - View Dependent Claims (28, 29)
