Comparative balancing
View Patent ↗In an example embodiment, an audio device is provided with one or more processors and a computer-readable tangible medium with instructions stored thereon that, when executed, direct the one or more processors to access a target audio file and access a set of evaluated levels associated with one or more preset frequency bands in the target audio file. The computer-readable tangible medium also has instructions that direct the processor to create a set of comparatively balanced levels by comparatively balancing a set of actual levels associated with the one or more preset frequency bands in the target audio file to at least approximate a set of reference levels associated with the one or more preset frequency bands. The computer-readable tangible medium further has instructions that direct the processor to play the target audio file with the set of comparatively balanced levels.

isolating one or more differences in the level settings between the set of evaluated levels and the set of reference levels;
utilizing the one or more differences in the level settings to alter a set of actual levels of the target audio file, the set of actual levels corresponding to the number of frequency bands in the template audio file selected;
creating a comparatively balanced audio signal for the target audio file using the altered set of actual levels, which at least approximates the set of reference levels; and
directing the comparatively balanced audio signal to be played on an audio device when the target audio file is selected for playback to create a more uniform listening experience for a user.
2. The non-transitory computer-readable tangible medium of claim 1 , further including instructions to direct a processor to perform acts comprising:
allowing a user to designate a chosen audio file as the template audio file.
3. The non-transitory computer-readable tangible medium of claim 1 , further including instructions to direct a processor to perform acts comprising:

generating a short-term average of levels associated with the number of frequency bands in the template audio file;
generating a non-continuous average of levels associated with the number of frequency bands in the template audio file through use of two or more temporally non-continuous samples of the template audio file.
4. The non-transitory computer-readable tangible medium of claim 1 , further including instructions to direct a processor to perform acts comprising:
creating at least a portion of the set of reference levels from a second set of levels associated with the number of frequency bands entered by a user.
5. The non-transitory computer-readable tangible medium of claim 1 , further including instructions to direct a processor to perform acts comprising:
accessing the target audio file by accessing a real-time stream of audio; and
creating the set of evaluated levels by monitoring the real-time stream of audio for a desired period of time.
6. An audio device comprising:
one or more processors;
one or more output devices; and
a non-transitory computer-readable tangible medium with instructions stored thereon that, when executed, direct the one or more processors to perform acts comprising:

selecting the number of frequency bands in the template audio file and accessing a set of reference levels associated with the number of frequency bands selected;
accessing a target audio file;
creating a set of evaluated levels using the target audio file by generating a non-continuous average of level settings for two or more temporally non-continuous samples from the target audio file for each frequency band in the number of frequency bands in the target audio file corresponding to the number of frequency bands in the template audio file selected;
isolating one or more differences in the level settings between the set of evaluated levels and the set of reference levels;
utilizing the one or more differences in the level settings to alter a set of actual levels of the target audio file, the set of actual levels corresponding to the number of frequency bands in the template audio file selected;
creating a comparatively balanced audio signal for the target audio file using the altered set of actual levels, which at least approximates the set of reference levels; and
directing the comparatively balanced audio signal to be played on at least one of the one or more output devices when the target audio file is selected for playback to create a more uniform listening experience for a user.
7. The audio device of claim 6 , wherein the non-transitory computer-readable tangible medium further includes instructions to direct the one or more processors to perform acts comprising:
allowing a user to designate a chosen audio file as the template audio file.
8. The audio device of claim 7 , wherein the non-transitory tangible computer-readable tangible medium further includes instructions to direct the one or more processors to perform acts comprising:
creating the set of reference levels associated with the number of frequency bands selected by one or more of:
