Abstract

A procedure and apparatus for generating automatic replay of recordings.

Claims

1. A procedure for controlling the playback of recordings from a collection of recordings, said collection of recordings being stored in digital form in at least one location or in a distributed storage system, each recording being classified in a multidimensional parameter space common to all recordings stored, according to pre-defined or self-organizing parameters, the procedure comprising

inputting a playback order structured as a generally fuzzy expression of general characteristics by:

inputting the fuzzy expression in the form of one or several seed recordings, said seed recordings being classified in the same multidimensional parameter space used for the collection,

comparing the multidimensional classification to combinations of classifications identifying each recording in said collection,

outputting, for playback, a list of access codes for those recordings having parameters fulfilling a multidimensional distance criterion with respect to the seed recording(s), the list being a circular list ordered according to the distance to the seed recording(s),

using the list to access sequentially the recordings concerned from the storage system,

wherein the user has access to all individual tracks via a wheel-like selection device which rotates/selects in both directions; and

wherein a plurality of playlists is generated, and further comprising;

executing all plavlists in parallel,

the user enabling a playlist to be active for the user,

automatically activating a new playlist upon completion of an actual playlist, and

the user forcing selection of another playlist to be active.

2. A procedure according to claim 1, wherein the pre-defined parameters are based on running spectral analyses for each recording combined with rhythm analyses.

3. A procedure according to claim 1, wherein the classification of each recording includes defining the multidimensional vectorial distances between self-organizing clusters obtained by applying running spectral analyses and rhythm analyses for the collection of recordings.

4. A procedure according to claim for adding a recording to the collection, wherein the recording is subjected to running spectral analyses for each recording combined with rhythm analyses of the types that were applied to the prior members of the collection, and associating the classification with the access code for the added recording.
