Sound quality enhancement and personalization

A computer-implemented method comprising:

• receiving one or more user inputs indicating user-specific information of a user of an audio playback device;
• receiving a device-specific frequency response that compensates for a measured characteristic frequency response of the audio playback device;
• receiving a target frequency response curve that is based on a plurality of preferred frequency responses, wherein each preferred frequency response is selected by at least one user of a plurality of users, and the at least one user is associated with at least a portion of the user-specific information;
• generating a personalized acoustic filter response based on a combination of the target frequency response curve and the device-specific frequency response;
• and
• based on the personalized acoustic filter response, adjusting a frequency response of the audio playback device.

A computer-implemented method comprising:

• receiving a first user ranking of a first acoustic filter response and a second user ranking of a second acoustic filter response, wherein each of the first acoustic filter response and the second acoustic filter response is generated from a respective target frequency response based on a plurality of preferred frequency responses, and each preferred frequency response is selected by at least one user of a plurality of users;
• based on the first user ranking and the second user ranking, generating a third acoustic filter response;
• and
• based on the third acoustic filter response and a previously measured characteristic frequency response of an audio playback device, adjusting a frequency response of the audio playback device.
