Abstract

Techniques for storing and retrieving processing properties for processing an audio signal in an audio processing system, such as, an audio mixing console are provided. The processing properties specify audio effects and/or audio mixing applied to the audio signal. Type information is established which relates to audio content properties of the audio signal. The type information allows classifying audio signals based on their audio content. Based on the type information, processing parameters are stored in a database and/or retrieved from the database.

Claims (71)

1. A method of retrieving processing properties for processing of an audio signal in an audio processing system, wherein the processing properties specify audio effects and/or audio mixing applied to the audio signal when processing the audio signal, the method comprises:

receiving the audio signal, at an audio input of the audio processing system;

establishing type information for the received audio signal, wherein the type information relates to audio content properties of the audio signal; and

depending on the established type information, retrieving the processing properties for the audio signal from a database of processing properties,

wherein the database associates type information with processing properties, and

wherein the established type information includes at least one of a link to a previously received audio signal and a link to previously used processing properties.

2. The method of claim 1 ,

wherein establishing of the type information depends on characterizing a sound spectrum of the received audio signal.

3. The method of claim 1 ,

wherein establishing of the type information comprises:

determining a characterization of a sound spectrum of the received audio signal at a processor of the audio processing system,

comparing the determined characterization of the sound spectrum with previously determined characterizations of sound spectra of previously received audio signals,

in dependence of comparing the determined characterization of the sound spectrum with the previously determined characterizations of the sound spectra, determining the type information.

4. The method of claim 1 ,

wherein the established type information further includes at least one of the following:

a classification of an originator of the received audio signal;

an identification of an audio source of the received audio signal;

a link to reference audio content properties; and

a characterization of a sound spectrum of the received audio signal.

5. The method of claim 1 ,

wherein establishing of the type information comprises:

extracting at least one track from the received audio signal,

sending the extracted track, via an interface, to a remote server, the remote server being configured to characterize a sound spectrum of the track and to determine the type information in dependence of the characterized sound spectrum, and

receiving the type information via the interface from the remote server.

6. The method of claim 1 ,

wherein retrieving of the processing properties includes:

matching the established type information with a matched type information included in a set of previously determined type information, and

for the matched type information, retrieving from the database associated processing properties as the processing properties for the audio signal.

7. The method of claim 6 ,

wherein the set of previously determined type information comprises type information relating to audio signals previously received via an interface of the audio processing system and/or predetermined reference type information.

8. The method of claim 1 , further comprising:

detecting a speech input of a user,

recognizing a user command from the speech input using speech recognition techniques,

wherein establishing of the type information depends on the recognized user command.

9. The method of claim 1 , further comprising:

allocating at least one user interface of a plurality of user interfaces of the audio processing system for processing of the received audio signal, in response to said retrieving of the processing properties, and

processing the received audio signal using the retrieved processing properties and in dependence of a setting of the at least one allocated user interface to obtain a processed audio signal.

10. The method of claim 9 , further comprising:

displaying a label corresponding to a determined type information on a display of the audio processing system displaying a label corresponding to the determined type information,

wherein the display designates the allocated at least one user interface.

11. The method of claim 1 ,

wherein retrieving of the processing properties is selectively executed if the audio processing system is operated in a configuration mode,

wherein the configuration mode is activated upon at least one of the following:

a user input;

a predetermined repetition time; and

detecting a change in the established type information during processing of the audio signal.

12. A method of generating a database of processing properties for processing of an audio signal in an audio processing system, wherein the processing properties specify audio effects and/or audio mixing applied to the audio signal when processing the audio signal, the method comprising:

receiving an audio signal, at an audio input of the audio processing system, and

processing the audio signal using processing properties, wherein the processing properties depend on a setting of at least one user interface of the audio processing system,

establishing type information for the received audio signal, wherein the type information relates to audio content properties of the audio signal, and

storing the processing properties and the type information in the database, and

wherein the established type information includes at least one of a link to a previously received audio signal and a link to previously used processing properties.

13. The method of claim 12 , further comprising

associating, at the database, type information with the processing properties.

14. An audio processing system, comprising:

an audio input configured to receive an audio signal,

a processor configured to establish type information for the received audio signal, wherein the type information relates to audio content properties of the audio signal,

wherein the processor is further configured to retrieve processing properties for the audio signal from a database of processing properties depending on the type information,

wherein the database associates type information with the processing properties,

wherein the processing properties specify audio effects and/or audio mixing applied to the audio signal when processing the audio signal in the audio processing system, and

wherein the established type information includes at least one of a link to a previously received audio signal and a link to previously used processing properties.

15. The audio processing system of claim 14 , wherein the processor is further configured to establish the type information based on characterizing a sound spectrum of the received audio signal.

16. The audio processing system of claim 14 wherein the established type information further includes at least one of the following:

a classification of an originator of the received audio signal;

an identification of an audio source of the received audio signal;

a link to reference audio content properties; and

a characterization of a sound spectrum of the received audio signal.

17. The audio processing system of claim 14 , further comprising an interface configured to send an extracted track from the received audio signal to a remote server, the remote server being configured to characterize a sound spectrum of the track and to determine the type information in dependence of a characterized sound spectrum.

18. The audio processing system of claim 17 wherein the interface is further configured to receive the type information from the remote server.

19. The audio processing system of claim 14 further comprising a display configured to display a label corresponding to a determined type information.

20. The audio processing system of claim 19 wherein the display is further configured to designate at least one allocated user interface.
