A scheme for localizing a wireless user equipment (UE) device's relative position with respect to a spatial configuration based on audio signatures received via a multi-channel audio system, e.g., an audio system of a vehicle or home entertainment system. The wireless UE device is configured to capture the audio signatures received from a head unit that are placed in an out-of-hearing band of a captured signal. The wireless UE device includes a persistent memory module having program instructions for processing the captured signal including the out-of-band signatures, which may comprise either channel-specific pseudo-random noise (PN) sequences or single-frequency tones, in order to compute time delays or power levels associated with the speaker channels. A localization module is configured to estimate the wireless UE device's relative position based on the time delays or power levels.
