First Claim
1. A method for providing a virtualized audio file, comprising:
- receiving a user location and a user angular direction;
receiving a virtualized audio file;
receiving a sound signal associated with at least one sound and a transmitting location;
processing the virtualized audio file based on;
the user location,the user angular direction, andthe sound signal,to produce a modified virtualized audio file, such that a user listening to the modified virtualized audio file would perceive the at least one sound originating from the transmitting location, if listening to the virtualized audio file via;
ear speakers,headphones, orwearable computing device; and
outputting the modified virtualized audio file,wherein the ear speakers, headphones, or wearable computing device comprises a transducer apparatus,wherein the transducer apparatus comprises;
at least one left transducer for converting a virtualized left channel signal into sound for presentation to a left ear of the user; and
at least one right transducer for converting a virtualized right channel signal into sound for presentation to a right ear of the user,wherein when the modified virtualized audio file is provided to the transducer apparatus and the user listens to the sound from the at least one left transducer via the left ear of the user, and listens to the sound from the at least one right transducer via the right ear of the user, the user perceives the at least one sound originating from the transmitting location, andwherein the method further comprises;
capturing information regarding one or more of the following;
a position of the transducer apparatus;
an angular direction of the transducer apparatus;
movement of the transducer apparatus; and
rotation of the transducer apparatus; and
processing the modified virtualized audio file based on the captured information to produce a processed modified virtualized audio file, such that when the virtualized left channel signal and the virtualized right channel signal based on the processed modified virtualized audio file are converted to sound and the user listens to the sound from the at least one left transducer via the left ear of the user, and listens to the sound from the at least one right transducer via the right ear of the user, the user perceives the at least one sound originating from the transmitting location even if the position of the transducer apparatus changes, an angular direction of the transducer apparatus changes, there is movement of the transducer apparatus, or there is rotation of the transducer apparatus.

Abstract
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.
