Abstract: A method for simulation of movement of a sound source comprising convolving a source wave form with at least an Head Related Transfer Function (HRTF) to generate a point sound source at a simulated first distance from the listener, generating a spherical harmonic representation of the source waveform at a simulated second distance from the listener, crossfading the sound level of the point sound source and the spherical harmonic representation of the source waveform at a simulated second distance from the listener and driving a speaker with the cross-faded spherical harmonic representation of the source waveform and the point sound source.

Abstract: Aspects of the present disclosure relate to techniques for adjustment of room sound levels, comprising; driving a speaker with a known waveform, detecting a sound wave from the speaker with at least two microphones wherein the at least two microphones are configured in a known orientation, utilizing the known waveform and the sound wave detected by the at least two microphones and the known orientation of the at least two microphones to generate a room sound dynamic; applying a filter to adjust a sound level to account for the room sound dynamic. The room sound dynamic may be the speaker layout of the room, the room impulse response, the distance or angle of each speaker from the center of the room or other physical constraints that may affect the user's perception of sound coming from a sound system.

Abstract: A method for improved virtual localization of sound comprises making a sound at an origin point, recording the sound with two or more recording devices at, two or more different distances from the origin point, generate a head-related transfer function (HRTF) for each of signals received from the two or more recording devices at the two or more different distances from the origin point, convolving a waveform with a localized HRTF generated using at least one of the HRTFs, and drive a speaker with the convolved waveform.

Abstract: A method for localization of sound in a speaker system comprises determining speaker locations of a plurality of speakers in a speaker system, determining a user location of a user within a room, and modifying audio signals to be transmitted to each of the plurality of speakers based on the user location in the room relative to a corresponding one of the speaker locations. An optimum modification of the audio signals for each of the plurality of speakers includes eliminating locational effects of the user location within the room.

Abstract: Aspects of the present disclosure relate to a method and system for processing an audio signal to optimize the localization of sound in a sound system using a head related transfer function HRTF). A location of a user is determined and a speaker is driven with a waveform representing a location specific cue having a desired user response. The location specific cue is associated with a defined HRTF for the determined location of the user. A user response to location specific cue is detected and compared to the location specific cue. The defined HRTF is then updated with information from the comparison of the user response to the location specific cue.

Abstract: A detector located on or near an ear piece may automatically detect whether a left or right ear or neither ear is wearing the ear piece. A signal mixer may automatically apply a correct configuration to signals transmitted to or from the ear piece according to whether the left or right ear or neither ear is determined to be wearing the ear piece. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
