Abstract

At an apparatus (200), which may be a consumer electronic device, the user may select a predetermined number of different music attributes (Attr) descriptive of a mood delivered by music represented by music content of a music file. From parameters of a music file available in the apparatus (200), the apparatus (200) determines a first vector (m₁(Dat)) descriptive of a relationship between the music content and all selected music attributes (Attr) and a second vector (m₂(Dat)) and outputs a classification information related to the music file and containing the first and second vectors (m₁(Dat), m₂(Dat)). The classification information may be used to assign a colour to a displayed object assigned to the music file. Perceptually similar music files may be displayed in similar colours.

Claims

1. A method of operating an apparatus evaluating music files, the method comprising:

selecting, at the apparatus, a predetermined number of different music attributes descriptive of a mood of a piece of music included in a music file;

determining, from parameters of a target music file available in the apparatus, a first vector descriptive of a relationship between the target music file and the selected music attributes and a second vector descriptive of a relationship between the target music file and a subset of the music attributes; and

outputting classification information containing the first and second vectors.

2. The method of claim 1, further comprising

displaying an object on a display in dependence on the classification information.

3. The method of claim 2, wherein

the first vector determines a graphic attribute and the second vector determines a position of the displayed object.

4. The method of claim 1, wherein

similar first vectors identify perceptually similar music content in at least two different genres.

5. The method of claim 1, wherein

the predetermined number of different music attributes is three.

6. The method of claim 5, wherein

each selected music attribute is assigned to another fundamental colour and the first vector determines the colour of the displayed object.

7. The method of claim 6, wherein

the object includes colour information related to two selected music attributes.

8. The method of claim 6, wherein

the object includes an area having a colour that is a combination colour mixed from the two fundamental colours assigned to the two closest selected music attributes.

9. The method of claim 1, further comprising

sensing a user selection of one or a subset of the displayed objects.

10. An electronic device including

a user entry unit configured to be operated by a user, wherein a user can select a predetermined number of different music attributes descriptive of a mood of a piece of music contained in a music file;

a calculator unit configured to determine, from parameters of a target music file available in the electronic device, a first vector descriptive of a relationship between the target music file and all selected music attributes and a second vector descriptive of a relationship between the target music file and a subset of the music attributes, the calculator unit further being configured to output classification information containing the first and second vectors.

11. The electronic device of claim 10, further comprising

a display for displaying objects;

and

a display control unit configured to control the display to display objects assigned to a plurality of music files in dependence on their classification information, wherein for each displayed object,

the second vector determines the position of the object, and

the first vector determines a colour of at least a sub-area of the object.

12. The electronic device of claim 11, wherein

the object includes colour information related to at least two selected music attributes.

13. The electronic device of claim 11, wherein

the object includes at least a sub-area having a colour that is a combination colour mixed from the two colours assigned to the two closest music attributes.

14. The electronic device of claim 10, wherein

the user entry unit is further configured to sense a user selection of one or more of the displayed objects, a colour or a colour range.

15. The electronic device of claim 10, wherein

the predetermined number of different music attributes is three.
