Definitions

  • the present invention relates to a computer as defined in the preamble of claim 1 , a computer program product as defined in the preamble of claim 6, a hand-held unit as defined in the preamble of claim 10 and a method as defined in the preamble of claim 11.
  • DJ systems comprise two record players to enable the playing of two music tracks at the same time and two sets of controls to enable manipulation of each track individually.
  • Typical parameters to control include:
  • Crossfade gradually changing from one channel to another channel by increasing the volume of one channel in at the same time as fading the other one out.
  • Pitch changing the speed at which a track is played to adapt the speed of two tracks to each other.
  • Bend temporarily changing the speed at which a track is played, to synchronize the beat of two tracks with each other to make a seamless transition between them.
  • Pause/play to start and stop the playback of a channel.
  • Cue stop playback and set the playback position to the cue point; a user set position in the track.
  • DJ systems Since it has become possible to store music in data files on hard disks or other memory, DJ systems have been developed in which the songs that are to be played are stored in a memory, for example, a data base from which they can be retrieved and played when desired. Typically these systems comprise similar functions to the traditional DJ systems in that they enable the mixing of two tracks and manipulation of each of the tracks to achieve a good mix, for example, a smooth transition between two songs.
  • the parameters used to achieve a certain mix can be stored in a mix instructions file and applied to the music files at a later time.
  • a mix instructions file can be created, for example, by registering the actions performed during a DJ session, that is, which music tracks are used and how the DJ manipulates them. This may be assisted by software that, for example, adjusts the playback speed of two tracks.
  • the mix instructions file can comprise data such as the music files' identification number, the point in each music file where the playback should start from, and if bend and/or pitch should be applied, how much and at which point.
  • the system may apply the data in the mix instructions file to create the same mix again based on the same music files, which are stored in the system. This is a great im- provement over the method previously known, which was to record the entire mix. Also, this system makes it easier to edit the mix since the parameters set in the mix instruction file can be altered instead of recording the entire mix again.
  • a computer connect- able to a data network and arranged to provide an audio output signal comprising a mix of at least two music tracks, said computer comprising: A first data base holding at least one music track file;
  • a second data base holding at least one mix instructions file, said mix instructions file comprising instructions including an indication of at least one music track and at least one function used to manipulate the output of the music track;
  • a playback unit arranged to provide the audio output signal by manipulating the at least one music track as specified in the mix instructions file;
  • a search unit arranged to determine if the at least one music track file is found in the first data base and
  • a retrieval unit arranged to connect to a music track data base through a data net- work to retrieve information related to at least one music track file from the music track data base based on the indication of the at least one music track if it is not found in the first data base.
  • the search unit is arranged to perform the following steps: - search a mix instructions file, said mix instructions file comprising instructions including an indication of at least one music track and at least one function used to manipulate the output of the music track, to find all music tracks indicated in the mix instructions file;
  • a computer program product for use in a computer as defined above, said computer program product comprising a computer readable code means which, when executed in said computer causes the computer to perform the following steps:
  • mix instructions file comprising instructions in- eluding an indication of at least one music track and specifying at least one function used to manipulate the output of the music track, to find all music tracks indicated in the mix instructions file
  • a hand-held unit arranged to provide an audio output signal comprising a mix of at least two music tracks, said computer comprising:
  • a second data base holding at least one mix instructions file said mix instructions file comprising instructions including an indication of at least one music track and specification of at least one function used to manipulate the output of the music track,
  • a playback unit arranged to provide the audio output signal by manipulating the at least one music track as specified in the mix instructions file.
  • the method and apparatus according to the invention enable easy sharing of the mix instructions files in a more flexible way than with, for example, the TRAKTOR system.
  • the TRAKTOR system only enables playback of the files using exactly the files that were used when creating the mix instruction files. Hence, when sharing a mix instruction file the files must be exported as well. Because the mix instructions files are much smaller than the files comprising the complete mix of two or more tracks they can be shared, or transported, more easily. Also, copyright issues can be avoided since sharing the mix instructions file does not infringe the copyright. Each user can then provide legal copies of the desired music files for themselves.
  • the invention can also encourage use of legal sources when downloading music, since the program may be arranged to search for music only in authorized data ba- ses.
  • the provider of the DJ system can reach a business agreement with the various copyright holders, for example, so that each time a user of the DJ system legally downloads and pays for a mu- sic track, the provider of the DJ system gets a part of the amount paid for the music track.
  • the provider may get paid per DJ system connected to the data bases, and/or per time unit instead. This provision paid to the provider of the system will further motivate making mix instructions files based on legal copies of music tracks and sharing these with others.
  • the retrieval unit is a computer program or part of a computer program arranged to retrieve the music tracks themselves from the music track data base.
  • the retrieval unit is arranged to retrieve information related to the music tracks from the music track data base said computer further arranged to display the retrieved information through the computer's user input/output unit.
  • the input/output means of the computer is preferably arranged to prompt the user to retrieve the music tracks from the music track data base.

  • FIG. 3 is a flow chart of an overall method according to the present invention.
  • FIG. 1 shows a DJ system 1 known in the art, using computer files comprising music tracks.
  • the system 1 comprises a computer 3 comprising a first data base 5 for music tracks.
  • the system also comprises traditional DJ functions 7 for manipulating at least one of the tracks stored in the first data base 5, for example, regarding playback speed (the bend and pitch parameters discussed above) to mix the tracks in a desired way.
  • the computer has user input/output means represented by a keyboard 6 and a screen 8. Of course other input/output means may be present, such as a mouse or console input means for physically manipulating a music track.
  • the system 1 also comprises a mix instructions file creation software program 9 arranged to store information about the music tracks used and how they are manipu- late by means of the DJ functions 7 to achieve the mix. This information is stored as parameter values in a mix instructions file, which is stored in a second data base 11.

  • FIG 2 illustrates a DJ system according to the invention.
  • a computer 23 comprises a first data base 25 for holding music tracks and a second data base 27 for holding mix instructions files similar to the ones known in the art.
  • the computer has user input/output means represented by a keyboard 6 and a screen 8.
  • the user input/output means may be used to inform the user about the options available, for example the music tracks and mix instructions files found in the first and second data base, respectively.
  • the computer may also comprise traditional DJ functions 29 and a mix instructions file creation software program 31 similar to the ones known in the art arranged to create mix instructions files and store them in the second data base 27.

  • the computer comprises a playback software program 33 arranged to retrieve a mix instructions file from the second data base 27 and, as pre- scribed in the mix instructions file, to retrieve at least one music track at a time from the first data base 25 and manipulate them according to the mix instructions file to create a mix of the music tracks.
  • the computer also has retrieval software 35 for retrieving, through a data network 36, mix instructions files and/or music tracks from sources such as a music track data base 37 or a mix instructions file data base 39 in the network.
  • the sources are not necessarily data bases; music tracks or mix instructions files can be retrieved from any kind of source in the network.
