US Patent 10129682 Method and apparatus to provide a virtualized audio file

Embodiments of the subject invention relate to a method and apparatus for virtualizing an audio file. The virtualized audio file can be presented to a user via, for example, ear-speakers or headphones, such that the user experiences a change in the user's perception of where the sound is coming from and/or 3D sound. Embodiments can utilize virtualization processing that is based on head rotated transfer functions (HRTF's) or other processing techniques that can alter where the user perceives the sounds of the music file to originate from. A specified embodiment provides Surround Sound virtualization with DTS Surround Sensations software. Embodiments can utilize the 2-channel audio transmitted to the headphones.
