Method and apparatus for providing virtualized audio files via headphones

摘要

Embodiments of the subject invention relate to a method and apparatus for providing virtualized audio files. Specific embodiments relate to a method and apparatus for providing virtualized audio files to a user via in-ear speakers or headphones. A specified embodiment can provide Surround Sound virtualization with DTS Surround Sensations software. Embodiments can utilize the 2-channel audio transmitted to the headphones. In order to accommodate for the user moving the headphones in one or more directions, and/or rotating the headphones, while still allowing the user to perceive the origin of the audio remains is a fixed location, heading data regarding the position of the headphones, the angular direction of the headphones, the movement of the headphones, and/or the rotation of the headphones can be returned from the headphones to a PC or other processing device. Additional processing of the audio files can be performed utilizing all or a portion of the received data to take into account the movement of the headphones.

1. A method of providing a virtualized audio file to a user, comprising:
transmitting a virtualized audio file to a transducer apparatus worn by a user, 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; andat 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 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 experiences localization of certain sounds in the virtualized audio file; 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, androtation of the transducer apparatus; and processing the virtualized audio file based on the captured information to produce a processed virtualized audio file, such that when the virtualized left channel signal and the virtualized right channel signal based on the processed 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 localization of the certain sounds experienced by the user remains in a fixed location, wherein capturing information comprises capturing information regarding the position of the transducer apparatus and information regarding the angular direction of the transducer apparatus, wherein capturing information comprises capturing information regarding movement acceleration of the transducer apparatus and information regarding rotational acceleration of the transducer apparatus, wherein processing the virtualized audio file based on the captured information comprises: a. inputting captured information regarding the position of the transducer apparatus and captured information regarding the angular direction of the transducer apparatus; b. inputting captured information regarding movement acceleration of the transducer apparatus and captured information regarding rotational acceleration of the transducer apparatus; c. calculating a new position and a new angular direction based on the captured information regarding the position of the transducer apparatus, the captured information regarding the angular direction, the captured information regarding movement acceleration of the transducer apparatus, and the captured information regarding rotational acceleration of the transducer apparatus; and d. processing the virtualized audio file using the new position and the new angular direction to produce the processed virtualized audio file, such that when the virtualized left channel signal and the virtualized right channel signal based on the processed 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 localization of the certain sounds experienced by the user remains in a fixed location.
