BRIEF SUMMARY
SPECIFICATION
BACKGROUND OF THE INVENTION
This invention relates to rearranging digital information with the use of a computer. In one aspect, the invention relates to rearranging sections of a music soundfile.
Many applications, such as multimedia, or radio and television advertisements, require set-length audio tracks to be produced. The usual method of doing this uses analog equipment. Audio tape is physically sliced with razor blades and reassembled to the desired length or recombined in a different order. Obviously, this technique is very labor-intensive and time-consuming. It also requires a high level of aural training. A technique which eliminates the need for musical skills in the sound editing process would be very desirable.
Each rearrangement of a musical composition using the prior art techniques as above required investments of time and training. A technique to cut down on the time and training required to produce rearrangements is needed.
The production of alternative versions of a rearrangement is often impractical using the prior an techniques because of time and expense constraints. While other computer music editing programs allow the user to manipulate digitally sampled audio data, the user must still make decisions about where edit points will be and in what order to rearrange the resulting pieces. The user must ensure that the final product comes as close as possible to the desired length. A technique to automatically generate new versions of a rearrangement having different musical characteristics and/or length would be very desirable.
SUMMARY OF THE INVENTION
In one embodiment of the invention, there is provided a process for forming a tool which can be used for the rearrangement of digital information files, such as music files. To practice the process, there is provided a digital information file and a digital instruction file which correlates to information in the digital information file. Appropriate edit points for the digital information file are determined and marker points are assigned to the instruction file which correlate to the previously determined edit points for the digital information file. The instruction file is then stored. The process is characterized in that the digital information file is of an artistic composition having continuity and structure and the edit points divide the artistic composition into units each having continuity and structure. When used with soundfiles, MIDI files, (Musical Information Digital Interface files), or motion image files, the process results in the identification of "blocks" of digital information which can be used to produce rearrangements of the original. When the edit points are professionally chosen, rearrangements based on the blocks will be as high in quality as if the new version was constructed by the professional editors themselves.
In another embodiment of the invention there is provided a process for rearranging a digital information file. To practice the process, there is provided a digital information file and a digital instruction file which divides the digital information file into a first arrangement of digital information units. A plurality of the digital information units are combined to form a second arrangement of digital information units, each unit in the second arrangement being taken from the first arrangement. The process is characterized in that the digital information file is of an artistic composition having continuity and structure and the digital instruction file comprises a plurality of predetermined markers. The location of the markers is based on artistically appropriate edit points for dividing the digital information file into a plurality of units. Each unit should have structure and continuity, and a beginning and an ending denoted by a marker. The process is especially useful for rearranging music as well as other art forms that lend themselves to recombinance, such as video and animation. When the edit points have been professionally predetermined for a soundfile, for example, it is a s
