Abstract

An audio language is used to generate audio sources for an audio scene. The audio sources are patterns comprising other patterns, composed music, audio samples, instruments, MIDI instruments, and filters. The audio files can be located on a computer-readable medium or accessible over a network. An audio player is provided for executing audio sources contained in audio files having code segments for the audio sources written in the audio language. The audio player prioritizes the audio sources according to prioritization reserved variables of the audio language to determine an order of priority. The audio player executes the audio sources according to the order of priority by transferring, playing, storing, or any combination of transferring, playing, and storing the audio sources according to the order of priority of the audio sources. The audio language and the audio player are advantageously useful for executing audio sources for an audio scene in a virtual environment.

A computer-readable medium according to claim 3, wherein the at least one reserved variable of the pattern data structure comprises at least one of an audio source reserved variable, a volume reserved variable, a pan reserved variable, a pitch reserved variable, a length reserved variable, a tempo reserved variable, an articulation reserved variable, a frequency modulation reserved variable, and a waveform modification reserved variable.

5. A computer-readable medium according to claim 3, wherein the pattern data structure further comprises at least one user-defined variable.

6. A computer-readable medium according to claim 1, wherein the first code segment comprises:

a sample data structure for describing audio in the audio source of the audio scene, wherein the sample data structure comprises;

a name for a first file containing audio samples; and

at least one reserved variable having a default value and for sampling the audio samples.

7. A computer-readable medium according to claim 6, wherein the at least one reserved variable of the sample data structure comprises at least one of a bass note reserved variable and a loop points reserved variable.

8. A computer-readable medium according to claim 1, wherein the first code segment comprises:

an instrument data structure for describing audio in the audio source of the audio scene as an instrument, wherein the instrument data structure comprises;

a name for a second file having audio data for sampling; and

at least one reserved variable having a default value and for adjusting the pitch range of the audio data of the second file.

9. A computer-readable medium according to claim 8, wherein the at least one reserved variable comprises one of a bottom reserved variable, a top reserved variable, and a sensitivity reserved variable.

10. A computer-readable medium according to claim 8, the instrument data structure further comprises:

another reserved variable for describing the attack, sustain, and release of the audio of the instrument data structure.

11. A computer-readable medium according to claim 8, wherein the instrument data structure further comprises at least one module for modifying the audio data of the second file.

12. A computer-readable medium according to claim 1, wherein the first code segment comprises:

a musical instrument digital interface ("MIDI") instrument data structure for describing the audio in the audio source of the scene as an instrument according to MIDI, wherein the MIDI data structure comprises;

a MIDI device identification reserved variable;

a MIDI channel number reserved variable; and

a MIDI program number reserved variable.

13. A computer-readable medium according to claim 1, wherein the first code segment comprises at least one variable, wherein the audio scene is dynamically evolved by varying the at least one variable of the first code segment.

14. A computer-readable medium according to claim 13, wherein the at least one variable of the first code segment is varied according to a triggering event.

15. A computer-readable medium according to claim 14, wherein the triggering event comprises a user interaction.

16. A computer-readable medium according to claim 1, wherein the code segments further comprise:

a third code segment for describing the audio scene and for identifying audio sources within the audio scene.

17. A computer-readable medium according to claim 16, wherein the third code segment comprises:

an audio scene data structure for describing the audio scene and for identifying audio sources within the audio scene, wherein the audio scene data structure comprises;

a name for an audio file containing the audio source; and

an audio start reserved variable for indicating a beginning of the audio scene.

18. A computer-readable medium according to claim 1, wherein the audio scene is part of a virtual environment.

19. A computer-readable medium according to claim 1, further comprising a fourth code segment for executing the audio source within the audio scene.
