The system can generate an acoustic model of a room and further calibrate speakers using the acoustic model. The audio adjustment and profile system can also use profile information associated with the listener to customize the listening experience based on the preference information in the profile information. The preference information can comprise mood preferences that emphasize certain frequencies and tones while limiting others. ## Claims ### Claim 1 A system, comprising: a processor; and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising: obtaining profile data representative of an audio profile of preference information of a user identity associated with a mobile device, wherein the preference information indicates a preference for an aural element of an audio playback of audio data; and generating an audio signal for a speaker based on the audio profile, an acoustic model that models how a defined speaker output sounds at a position in a defined area based on acoustical properties of the defined area, and a relative position of the mobile device from the speaker based on a first location of the speaker and a second location of the mobile device, wherein the audio signal being rendered by the speaker creates an aural experience at the second location that corresponds to the aural element of the audio playback. ### Claim 2 (depends on 1) The system of claim 1, wherein the aural element is associated with a sound source in the audio data. ### Claim 3 (depends on 2) The system of claim 2, wherein the aural element is a first aural element, and wherein the operations further comprise: adjusting a volume of the first aural element relative to a second aural element different than the first aural element. ### Claim 4 (depends on 1) The system of claim 1, wherein the audio signal being rendered by the speaker creates the aural experience at the second location that corresponds to a sound environment of a virtual reality environment. ### Claim 5 (depends on 1) The system of claim 1, wherein the aural element is associated with mood preference information in the preference information representative of a mood to be applied to the audio signal. ### Claim 6 (depends on 1) The system of claim 1, wherein the operations further comprise: generating a baseline audio signal for the speaker; and analyzing an audio recording received by a microphone in response to the speaker producing sound based on the baseline audio signal. ### Claim 7 (depends on 6) The system of claim 6, wherein the operations further comprise: estimating respective acoustic properties at a group of locations, the group of locations comprising the first location and the second location. ### Claim 8 (depends on 1) The system of claim 1, wherein the operations further comprise: tracking a movement of the mobile device; and adjusting the audio signal based on the movement. ### Claim 9 (depends on 1) The system of claim 1, wherein the operations further comprise: determining the second location via at least one of Wi-Fi tracking, network location tracking, near field communication tracking or video tracking. ### Claim 10 (depends on 1) The system of claim 1, wherein the operations further comprise: calibrating the acoustic model based on an analysis of an image of an area around the speaker. ### Claim 11 A method, comprising: retrieving, by a device comprising a processor, an audio preference profile associated with a mobile device, wherein the audio preference profile comprises information associated with a sound preference to be applied to a speaker; and generating, by the device, an audio signal for the speaker based on a sound recording, wherein an acoustic element of the sound recording is adjusted based on the audio preference profile, an acoustic model that facilitates prediction of a first acoustical property of a defined speaker output at a position in a defined area based on a second acoustical property of the defined area, and a relative position of the mobile device from the speaker based on a first location of the mobile device and a second location of the speaker. ### Claim 12 (depends on 11) The method of claim 11, further comprising: adjusting, by the device, a volume of the acoustic element relative to a different acoustic element in the sound recording. ### Claim 13 (depends on 11) The method of claim 11, further comprising: matching, by the device, a sound at the first location to an audio environment in a virtual world environment. ### Claim 14 (depends on 11) The method of claim 11, further comprising: determining the first location based on at least one of Wi-Fi tracking, network location tracking, near field communication tracking or video tracking. ### Claim 15 (depends on 11) The method of claim 11, wherein the audio preference profile comprises mood preference information representative of a mood to be applied to the audio signal. ### Claim 16 (depends on 11) The method of claim 11, further comprising: generating, by the device, a baseline audio signal for the speaker; analyzing, by the device, an audio recording associated with the baseline audio signal; and determining, by the device, the acoustic model based on a result of the analyzing. ### Claim 17 (depends on 11) The method of claim 11, further comprising: tracking, by the device, a movement of the mobile device; and adjusting, by the device, the audio signal based on the movement. ### Claim 18 (depends on 11) The method of claim 11, further comprising: calibrating, by the device, the acoustic model based on a result of analyzing an image captured of an area around the speaker. ### Claim 19 A machine-readable storage medium, comprising executable instructions that, when executed by a processor of a device, facilitate performance of operations, comprising: obtaining an audio preference profile associated with a mobile device, wherein the audio preference profile comprises information associated with a sound preference to be applied to a sound output of a speaker; and generating an audio signal for the speaker based on a sound recording, wherein an acoustic element of the sound recording is adjusted based on the audio preference profile, an acoustic model that models how a defined speaker output sounds at a point in a defined area based on acoustical properties of the defined area, and a relative position of the mobile device from the speaker based on a first location of the mobile device and a second location of the speaker. ### Claim 20 (depends on 19) The machine-readable storage medium of claim 19, wherein the acoustic element is a first acoustic element, and wherein the operations further comprise: based on the audio preference profile, adjusting a volume of the first acoustic element relative to a second acoustic element in the sound recording different than the first acoustic element.
