A method of generating a lighting effect based on metadata of an audio stream, the method comprising steps of:
- extracting one or more metadata items from the audio stream, wherein the metadata items comprise one or more of:
- artist, song title, album, genre and mood;
- ranking the metadata items from a highest ranked metadata item to a lowest ranked metadata item according to a ranking scheme;
- retrieving a first set of one or more images based on the value of the highest ranked metadata item;
- determining a color palette consistency of the set of images retrieved based on the highest ranked metadata item;
- if said color palette consistency meets or exceeds a threshold color palette consistency, controlling a light source to generate a lighting effect based on a color palette derived from said first set of one or more images;
- and else
- if said color palette consistency is less than a threshold color palette consistency, retrieving a second set of images based on the value of a second highest ranked metadata item according to said ranking and controlling a light source to generate a lighting effect based on a color palette derived from said second set of one or more images.
