Abstract
A method of sampling a music selection to produce a music clipping suitable for super distribution. A computer readable music file is sampled by defining a starting point for the sample at a fixed time from the beginning of the music selection. The stopping point is similarly selected as a fixed time from the starting point for the sample. The actual fixed times can be varied based upon the genre of the music when another embodiment flags or headers can be used to define the starting and ending time of the sample. Once the sample has been defined, data from the sample is extracted and compressed to reduce the file size to a size suitable for super distribution.
Claims58
An automated method of extracting a representative sample from a computer readable audio file, comprising:
- identifying a starting point for the representative sample in the audio file, the starting point being at a fixed time Tstart measured from the beginning of the audio file;
- identifying an ending point for the representative sample in the audio file, the ending point being at a fixed time Tstart+Tsample=Tstop from the beginning of the audio file;
- and
- storing audio data representing the audio between Tstart and Tstop as the representative sample of the audio file.
An automated method of extracting a representative sample from a computer readable file containing entertainment content, comprising:
- identifying a starting point for the representative sample in the file, the starting point being identified by information embedded within the file;
- identifying an ending point for the representative sample in the file, the ending point being identified by information embedded within the file;
- and
- storing data representing the content between the starting point and the ending point as the representative sample of the entertainment content contained in the computer readable file.
An electronic storage medium storing instructions which, when executed on a programmed processor, carry out an automated process of extracting a representative sample from content stored as a computer readable file, comprising:
- identifying a starting point for the representative sample in the file, the starting point being at a fixed time Tstart measured from the beginning of the file;
- identifying an ending point for the representative sample in the file, the ending point being at a fixed time Tstart+Tsample=Tstop from the beginning of the file;
- and
- storing data representing the content between Tstart and Tstop as the representative sample of the content of the computer readable file.
An electronic storage medium storing instructions which, when executed on a programmed processor, carry out an automated process of extracting a representative sample from content stored as a computer readable file, comprising:
- identifying a starting point for the representative sample in the file, the starting point being identified by information embedded within the file;
- identifying an ending point for the representative sample in the file, the ending point being identified information embedded within the file;
- and
- storing music data representing the content between the starting point and the ending point as the representative sample of the content of the computer readable file.
An automated method of extracting a representative sample from content stored in a computer readable file, comprising:
- identifying a starting point for the representative sample in the file, the starting point being at a fixed time Tstart measured from the beginning of the file;
- identifying an ending point for the representative sample in the file, the ending point being at a fixed time Tstart+Tsample=Tstop from the beginning of the file;
- and
- storing data representing the content between Tstart and Tstop as the representative sample of the content of the computer readable file.
An apparatus that automatically extracts a representative sample from a computer readable audio file, comprising:
- a programmed processor;
- a program operating on the programmed processor that identifies a starting point for the representative sample in the audio file, the starting point being at a fixed time Tstart measured from the beginning of the audio file, and identifies an ending point for the representative sample in the audio file, the ending point being at a fixed time Tstart+Tsample=Tstop from the beginning of the audio file;
- and
- means for storing audio data representing the audio between Tstart and Tstop as the representative sample of the audio file.
An electronic storage medium, comprising:
- a digital file containing electronic entertainment content;
- and
- instructions, embedded within the digital file, that define a starting point and an ending point of a predefined representative sample of the electronic entertainment content when read by a programmed processor.
An automated method of extracting a representative sample from a computer readable music file containing a selection of music, comprising:
- identifying a starting point for the representative sample in the music file, the starting point being at a fixed time Tstart measured from the beginning of the music file;
- identifying an ending point for the representative sample in the music file, the ending point being at a fixed time Tstart+Tsample=Tstop from the beginning of the music file;
- and
- storing audio data representing the audio between Tstart and Tstop as the representative sample of the music file.
An automated method of extracting a representative sample from a computer readable music file containing a selection of music, comprising:
- identifying a starting point for the representative sample in the music file, the starting point being at a fixed time Tstart measured from the beginning of the music file, where Tstart is between 30 and 60 seconds
- identifying an ending point for the representative sample in the music file, the ending point being at a fixed time Tstart+Tsample=Tstop from the beginning of the music file, where Tsample is between approximately 30 and 60 seconds and is selected based upon a music genre;
- storing audio data representing the audio between Tstart and Tstop as the representative sample of the music file;
- and
- compressing the audio data representing the audio between Tstart and Tstop by reducing a data rate of the audio data to produce a reduced fidelity sample.
