Abstract

Methods, apparatus, systems and articles of manufacture are disclosed for playback using pre-processed profile information and personalization. Example apparatus disclosed herein include a synchronizer to, in response to receiving a media signal to be played on a playback device, access an equalization (EQ) profile corresponding to the media signal; an EQ personalization manager to generate a personalized EQ setting; and an EQ adjustment implementor to modify playback of the media signal on the playback device based on a blended equalization generated based on the EQ profile and the personalized EQ setting.

Claims

1. An apparatus comprising:

a synchronizer to, in response to receiving a media signal to be played on a playback device, access an equalization (EQ) profile corresponding to the media signal;

an EQ personalization manager to generate a personalized EQ setting; and

an EQ adjustment implementor to modify playback of the media signal on the playback device based on a blended equalization generated based on the EQ profile and the personalized EQ setting.

2. The apparatus of claim 1, further including a historical EQ manager to:

generate the personalized EQ setting based on past personalization settings; and

in response to historical equalization being enabled, adjust the personalized EQ setting based on EQ settings associated with a previous period of time.

3. The apparatus of claim 1, further including a user input analyzer to:

in response to availability of data indicative of preferences of a user, determine EQ parameters based on the data indicative of preferences of the user, the EQ parameters corresponding to audio playback settings; and

adjust the personalized EQ setting based on the EQ parameters determined based on the data indicative of preferences of the user.

4. The apparatus of claim 1, further including a device parameter analyzer to:

in response to availability of location data of the playback device, adjust the personalized EQ setting based on the location data of the playback device;

in response to availability of identification of a user, adjust the personalized EQ setting based on a user profile; and

in response to availability of information associated with a source of the media signal, adjust the personalized EQ setting based on the source of the media signal.

5. The apparatus of claim 1, wherein the EQ adjustment implementor is to apply weights to a first personalized EQ setting, a second personalized EQ setting, and the EQ profile to generate the blended equalization.

6. The apparatus of claim 1, wherein the personalized EQ setting is based on at least one of EQ settings associated with a previous period of time, data indicative of preferences of a user, location data of the playback device, a user profile, or a source of the media signal.

7. The apparatus of claim 1, wherein the EQ profile includes playback attributes corresponding to at least one of (1) information identifying a category associated with a song, (2) information identifying a category associated with a video segment, (3) information identifying a mood associated with the song or the video segment, or (4) information identifying signal strength parameters for different frequencies with a portion of the media signal.

8. A non-transitory computer readable storage medium comprising instructions which, when executed, cause one or more processors to at least:

in response to receiving a media signal to be played on a playback device, access an equalization (EQ) profile corresponding to the media signal;

generate a personalized EQ setting; and

modify playback of the media signal on the playback device based on a blended equalization generated based on the EQ profile and the personalized EQ setting.

9. The non-transitory computer readable storage medium of claim 8, wherein the instructions, when executed, cause the one or more processors to:
