Abstract
Audio files for an audio piece are stored in cross-scene optimized manner, so that when reading out audio files for a scene entailing high utilization of a wave field synthesis system, very short memory access times are achieved, whereas for scenes not entailing such a high utilization of the wave field synthesis system, longer memory access times in turn are accepted.
Claims14
An apparatus for storing audio files for an audio piece in a storage device with a writer and a reader, wherein the audio piece is to be rendered by a renderer of a wave field synthesis system, wherein the audio piece comprises several scenes, wherein a scene description is provided for each scene, and wherein a scene defines a temporal sequence of audio objects of the scene, wherein an audio object comprises information on a virtual source and an identification for an audio file associated with the audio object, comprising:
- an examiner for examining the scene description and for determining a first scene demanding a higher processing capacity of the wave field synthesis system (3) than a second scene;
- and
- a controller for controlling the writer so that audio files being identified by the scene description of the first scene are written on the storage device so that the reader can read out the audio files for the first scene more quickly than if the audio files for the first scene are randomly stored on the storage device.
A method for storing audio files for an audio piece in a storage device with a writer and a reader, wherein the audio piece is to be rendered by a renderer of a wave field synthesis system, wherein the audio piece comprises several scenes, wherein a scene description is provided for each scene, and wherein a scene defines a temporal sequence of audio objects of the scene, wherein an audio object comprises information on a virtual source and an identification for an audio file associated with the audio object, comprising:
- examining the scene description and determining a first scene demanding a higher processing capacity of the wave field synthesis system than a second scene;
- and
- controlling the writer so that audio files being identified by the scene description of the first scene are written on the storage device so that the reader can read out the audio files for the first scene more quickly than if the audio files for the first scene are randomly stored on the storage device.
A computer program with program code for performing, when the computer program is executed on a computer, a method for storing audio files for an audio piece in a storage device with a writer and a reader, wherein the audio piece is to be rendered by a renderer of a wave field synthesis system, wherein the audio piece comprises several scenes, wherein a scene description is provided for each scene, and wherein a scene defines a temporal sequence of audio objects of the scene, wherein an audio object comprises information on a virtual source and an identification for an audio file associated with the audio object, the method comprising:
- examining the scene description and determining a first scene demanding a higher processing capacity of the wave field synthesis system than a second scene;
- and
- controlling the writer so that audio files being identified by the scene description of the first scene are written on the storage device so that the reader can read out the audio files for the first scene more quickly than if the audio files for the first scene are randomly stored on the storage device.
