In operation, the personalization application acquires first personalized audio content for a first user based on an emotional state associated with the first user. The personalization application then causes a first audio device associated with the first user to output the first audio content. In addition, the personalization application causes a second audio device associated with a second user that is co-located with the first user to output second audio content while the first audio devices outputs the first audio content. Notably, the second audio content is different from the first audio content. ## Claims ### Claim 1 A method for providing personalized audio content, the method comprising: determining, via one or more processors, a first emotional state associated with a first user based on sensor data from one or more sensors; acquiring, via the one or more processors, first personalized audio content based on the first emotional state associated with the first user; causing a first audio device associated with the first user to output the first audio content; and causing a second audio device associated with a second user that is co-located with the first user to output second audio content while the first audio device outputs the first audio content, wherein the second audio content is different from the first audio content. ### Claim 2 (depends on 1) The method of claim 1, further comprising acquiring the second audio content, wherein the second audio content is based on a second emotional state associated with the second user. ### Claim 3 (depends on 1) The method of claim 1, wherein the first user and the second user are occupants of a vehicle. ### Claim 4 (depends on 1) The method of claim 1, wherein the first audio device comprises at least one of an earbud and a speaker. ### Claim 5 (depends on 1) The method of claim 1, wherein the first personalized audio content includes at least one of musical content, speech content, and noise cancellation content. ### Claim 6 (depends on 1) The method of claim 1, wherein acquiring the first personalized audio content comprises determining that first source audio content is targeted for output to the first user, and modifying a first characteristic of the first source audio content based on the first emotional state to generate the first personalized audio content. ### Claim 7 (depends on 6) The method of claim 6, wherein the first characteristic comprises a frequency characteristic, a musical arrangement selection, an instrument selection, a pitch, a word choice, a type of information, a tone of voice, or a type of voice. ### Claim 8 (depends on 1) The method of claim 1, wherein acquiring the first personalized audio content comprises: determining that a first version of a first song is targeted for output to the first user; acquiring a second version of the first song, wherein the second version of the first song comprises a multi-track version of the first song or a Musical Instrument Digital Interface (MIDI) version of the first song; and performing one or more audio operations on the second version of the first song based on the first emotional state. ### Claim 9 (depends on 1) The method of claim 1, further comprising determining the first emotional state based on at least one of image data, biological data, auditory data, tactile data, and electronic activity data. ### Claim 10 (depends on 1) The method of claim 1, wherein acquiring the first personalized audio content comprises determining a goal emotional state based on the first emotional state and modifying first source audio content targeted for output to the first user based on the goal emotional state to generate the first personalized audio content. ### Claim 11 One or more non-transitory computer-readable storage media including instructions that, when executed by one or more processors, cause the one or more processors to provide personalized audio content by performing the steps of: determining, via one or more processors, a first emotional state associated with a first user based on sensor data from one or more sensors; acquiring, via the one or more processors, first personalized audio content based on the first emotional state associated with the first user; acquiring second personalized audio content based on a second emotional state associated with a second user that is co-located with the first user; causing a first audio device associated with the first user to output the first audio content; and causing a second audio device associated with the second user to output the second audio content while the first audio device outputs the first audio content. ### Claim 12 (depends on 11) The one or more computer-readable storage media of claim 11, wherein acquiring the first personalized audio content comprises determining that first source audio content is targeted for output to the first user, and modifying a first characteristic of the first source audio content based on the first emotional state to generate the first personalized audio content. ### Claim 13 (depends on 12) The one or more computer-readable storage media of claim 12, wherein acquiring the second personalized audio content comprises determining that the first source audio content is also targeted for output to the second user, and modifying at least one of the first characteristic and a second characteristic of the first source audio content based on the second emotional state to generate the second personalized audio content. ### Claim 14 (depends on 12) The one or more computer-readable storage media of claim 12, wherein acquiring the second personalized audio content comprises determining that second source audio content is targeted for output to the second user, and modifying at least one of the first characteristic and a second characteristic of the second source audio content based on the second emotional state to generate the second personalized audio content. ### Claim 15 (depends on 11) The one or more computer-readable storage media of claim 11, wherein acquiring the first personalized audio content comprises detecting that a first version of a first song is targeted for output to the first user, and selecting a second version of the first song based on the first emotional state. ### Claim 16 (depends on 11) The one or more computer-readable storage media of claim 11, wherein the first user and the second user are occupants of a vehicle. ### Claim 17 (depends on 11) The one or more computer-readable storage media of claim 11, wherein the first audio devices comprise at least one of an earbud and a speaker. ### Claim 18 (depends on 11) The one or more computer-readable storage media of claim 11, wherein the first personalized audio content includes at least one of musical content, speech content, and noise cancellation content. ### Claim 19 A system for providing personalized audio content, the system comprising: a memory storing a personalization application; and a processor coupled to the memory, wherein, when executed by the processor, the personalization application causes the processor to: for a first user included in a plurality of co-located users, determine an emotional state associated with the first user based on sensor data from one or more sensors; for the first user, acquire first personalized audio content based on the emotional state and source audio content; cause a first audio device associated with the first user to output the first personalized audio content; and cause a second audio device associated with a second user included in the plurality of co-located users to output the source audio content or second personalized audio content that is different from the first personalized audio content while the first audio device outputs the first audio content. ### Claim 20 (depends on 19) The system of claim 19, wherein the plurality of co-located users are occupants of a vehicle.
