Abstract

A method comprises providing an audio file comprising two or more discrete tracks; separating the two or more discrete tracks; setting a limit on an amount at least one of the two or more discrete tracks may be altered; and outputting the separated and limited discrete tracks as a file for use by an end user.

Claims

1. A method, comprising:

providing an audio file comprising two or more discrete tracks;

separating the two or more discrete tracks;

determining a limit on an ability to alter an amount of an effect, using a visual object, wherein the visual object is configured to be presented on a display so as to be manipulated, based on at least one of the two or more discrete tracks;

altering the amount of the effect;

determining if the limit on the ability to alter the amount of the effect is exceeded;

if the limit on the ability to alter the amount of the effect is exceeded, preventing the effect from being one or more of saved, copied, and published; and

outputting the separated discrete tracks for altering the amount of the effect.

2. The method of claim 1, wherein determining the limit on the ability to alter the amount of the effect comprises analyzing metadata associated with the audio file.

3. The method of claim 1, wherein altering the amount of the effect comprises applying a constant manipulation of a control.

4. The method of claim 1, wherein if the limit on the ability to alter the amount of the effect is not exceeded, further comprising authorizing one or more of saving, copying, and publishing the effect.

5. The method of claim 4, further comprising,

outputting the separated and limited discrete tracks as a file;

and

encrypting the outputted file.

6. The method of claim 1, wherein the limit on the ability to alter the amount of the effect is determined based on an estimated quality of a file format of the audio file.

7. The method of claim 6, wherein the estimated quality of the file format is determined from a computer program analysis.

8. The method of claim 6, wherein the estimated quality of the file format is based on a determination from a user or a creator of the audio file.

9. A method, comprising:

receiving an audio file comprising two or more discrete tracks;

analyzing the two or more discrete tracks to determine a limit on an ability to alter an amount of an effect, using a visual object based on manipulating an image on a display, based on at least one of the two or more discrete tracks;

altering the amount of the effect;

determining if the limit on the ability to alter the amount of the effect is exceeded;

if the limit on the ability to alter the amount of the effect is exceeded, preventing the effect from being one or more of saved, copied, and published; and

remixing the two or more discrete tracks.

10. The method of claim 9, further comprising separating the two or more discrete tracks from each other before analyzing.

11. The method of claim 10, wherein separating the two or more discrete tracks from each other is based on a blind signal separation format or a spatial audio object coding format.

12. The method of claim 9, wherein altering the amount of the effect comprises applying a constant manipulation of a control.

13. The method of claim 9, wherein the limit on the ability to alter the amount of the effect is determined based on an estimated quality of a format of the audio file.

14. An apparatus, comprising:

at least one processor; and

at least one non-transitory memory including computer program code configured to, with the at least one processor, cause the apparatus at least to;

receive an audio file comprising two or more discrete tracks;

analyze the two or more discrete tracks to determine a limit on an ability to alter an amount of an effect, using a visual object based on manipulating an image on a display, based on at least one of the two or more discrete tracks;

alter the amount of the effect;

determine if the limit for altering the amount of the effect for the at least one of the two or more discrete tracks is exceeded;

if the limit on the ability to alter the amount of the effect is exceeded, prevent the effect from being one or more of saved, copied, and published; and

allow a remix of the two or more discrete tracks.

15. The apparatus of claim 14, wherein the apparatus is further caused to separate the two or more discrete tracks from each other based on a blind signal separation format.

16. The apparatus of claim 14, wherein the apparatus is further caused to separate the two or more discrete tracks from each other based on a spatial audio object coding format.

17. The apparatus of claim 14, wherein the apparatus is further caused to output the remix of the two or more discrete tracks.

18. The apparatus of claim 14, wherein if the limit on the ability to alter the amount of the effect is determined to be not exceeded, an authorization is provided for one or more of saving, copying, and publishing the effect.
