Abstract

A method of geotagging an audio-recording. The method comprises: determining (220) a location at which the audio-recording was recorded; obtaining (230) an image containing an indication of the location, or a reference to a file containing such an image; and creating (215, 240) a single file (1) containing: the audio-recording (4); and the image (8) or a reference to a separate file that contains the image. The indication of the location comprises at least one of: a map (8a) that includes the location; an aerial or satellite photograph that includes the location; and text (8b) overlaid on the image to specify the location.

Claims

1. A method of geotagging an audio-recording, comprising:

determining (220) a location at which the audio-recording was recorded;

obtaining (230) an image containing an indication of the location, or a reference to a file containing such an image; and

creating (215, 240) a single file (1) containing;

the audio-recording (4); and

the image (8) or a reference to a separate file that contains the image,

wherein the indication of the location comprises at least one of;

a map (8a) that includes the location;

an aerial or satellite photograph that includes the location; and

text (8b) overlaid on the image to specify the location.

2. The method of claim 1, wherein the indication of the location comprises a map (8a) or an aerial or satellite photograph including the location, and

the map or photograph contains a mark (8c) identifying the position of the location on the map or photograph.

3. The method of claim 1, wherein the image (8) is contained in a portion (2) of the single file (1) reserved for metadata.

4. The method of claim 3, wherein the file (1) is an MP3 file and the image (8) is embedded in an Attached Picture frame according to the ID3v2 specification.

5. The method of claim 1, wherein the location at which the audio-recording was recorded is also described in one or more textual or numerical metadata tags of the single file.

6. The method of claim 5, wherein the single file is an MP3 file and the location is described in a Unique File Identifier frame according to the ID3v2 specification.

7. The method of claim 1, wherein the image (8) is provided as a JPEG file (6) and the location at which the audio-recording was recorded is also described in one or more EXIF metadata tags (7) of the JPEG file (6).

8. The method of claim 1, wherein the location of recording changed during the course of the recording, and wherein the indication of the location describes at least one of:

a plurality of discrete locations;

a location-range, or a trajectory.

10. A computer program comprising computer program code means adapted to control a computer to perform all the steps of claim 1 if said program is run on the computer.

11. A computer program as claimed in claim 10 embodied on a computer readable medium.

9. A method of geotagging an audio-recording with a location at which it was recorded, comprising:

creating a digital audio file containing the audio-recording; and

describing the location in one or more metadata tags of the digital audio file,

wherein the audio file is an MP3 file and the location is described in a Unique File Identifier frame according to the ID3v2 specification.

12. A computer program comprising computer program code means adapted to control a computer to perform all the steps of claim 9 if said program is run on the computer.

13. A computer program as claimed in claim 12 embodied on a computer readable medium.

14. A digital audio file (1) comprising an audio-recording (4) and an image (8) or a reference to a separate file that contains an image, wherein the image comprises at least one of:

a map (8a) that includes a location at which the audio-recording was made;

an aerial or satellite photograph that includes the location; and

text (8b) overlaid on the image to specify the location.

15. A digital audio file (1) comprising an audio-recording (4) and at least one metadata tag (2), wherein the tag describes a location at which the audio-recording was made, and

wherein the audio file is an MP3 file and the location is described in a Unique File Identifier frame according to the ID3v2 specification.

16. Apparatus for geotagging an audio recording, the apparatus comprising:

a memory (32, 132) for storing the audio recording; and

a processor (34, 134), adapted to;

determine a location at which the audio recording was made;

obtain an image (8) indicating the location or a reference to a file containing such an image; and

create, in the memory (32, 132), a single file (1) containing;

the audio-recording (4); and

the image (8) or a reference to a separate file that contains the image,

wherein the image indicates the location by means of at least one of;

a map (8a) that includes the location;

an aerial or satellite photograph that includes the location; and

text (8b) overlaid on the image to specify the location.

17. Apparatus for geotagging an audio recording comprising:

a memory (32, 132) for storing the audio recording; and

a processor (34, 134), adapted to;

determine a location at which the audio recording was made; and

create, in the memory, a digital audio file (1) containing the audio-recording (4) and one or more metadata tags (2) describing the location,

wherein the audio file is an MP3 file and the location is described in a Unique File Identifier frame according to the ID3v2 specification.
