The UWB radio can receive UWB ranging data from the UWB radios associated with the speakers. An audio controller can utilize the UWB ranging data to monitor locations of the wireless device relative to the speakers and determine a location change of the wireless device relative to the speakers. The audio controller can communicate audio adjustment instructions based on the locations of the wireless device relative to the speakers or relative to the location change of the wireless device. The audio adjustment instructions can initiate an adjustment of a sound level of the audio emitted from at least one of the speakers and/or initiate a delay in the audio emitted from at least one of the speakers. ## Claims ### Claim 1 A wireless device, comprising: an ultra-wideband (UWB) radio to communicate with one or more UWB radios respectively associated with speakers emitting audio, the UWB radio configured to receive UWB ranging data from the one or more UWB radios; and an audio controller implemented at least partially in hardware to: monitor locations of the wireless device relative to the speakers based on the UWB ranging data received from the one or more UWB radios; identify at least one speaker that is closer to the wireless device than at least one other speaker based on comparing the locations of the wireless device relative to the speakers; and communicate audio adjustment instructions to initiate a sound level adjustment of the audio emitted from the at least one speaker based on a ratio of a distance from the wireless device to the at least one speaker to an average distance from the wireless device to the speakers, the sound level adjustment including increasing a volume of the at least one speaker while decreasing a volume of the at least one other speaker relative to the volume of the at least one speaker as the wireless device moves closer to the at least one speaker. ### Claim 2 (depends on 1) The wireless device of claim 1, wherein the locations of the wireless device include a first location determined as a reference distance from the wireless device to the at least one speaker and at least a second location determined as a subsequent distance from the wireless device to the at least one speaker. ### Claim 3 (depends on 2) The wireless device of claim 2, wherein the audio adjustment instructions to initiate the sound level adjustment of the audio emitted from the at least one speaker are based on a ratio of the subsequent distance to the reference distance. ### Claim 4 (depends on 2) The wireless device of claim 2, wherein the audio adjustment instructions include initiating a delay in the audio emitted from the at least one speaker in response to the subsequent distance from the wireless device to the at least one speaker is at a different distance than the reference distance. ### Claim 5 (depends on 1) The wireless device of claim 1, wherein the locations of the wireless device include a first location determined as the average distance from the wireless device to the speakers and at least a second location determined as a subsequent distance from the wireless device to the at least one speaker. ### Claim 6 (depends on 1) The wireless device of claim 1, wherein the audio adjustment instructions are communicated to the at least one speaker to initiate the sound level adjustment of the audio emitted from the at least one speaker. ### Claim 7 (depends on 1) The wireless device of claim 1, wherein the audio adjustment instructions are communicated to an amplifier controlling the at least one speaker to initiate the sound level adjustment of the audio emitted from the at least one speaker. ### Claim 8 (depends on 1) The wireless device of claim 1, further comprising a user interface configured to receive a position input specifying a reference position of the wireless device relative to the speakers, and at least one of: receive an adjustment input specifying the sound level adjustment as a reduce-only sound level adjustment;
