Abstract: An audio system, method, and computer program product which includes a wearable audio device and a peripheral device. Each device is capable of determining its respective absolute or relative position and orientation. Once the relative positions and orientations between the devices are known, virtual sound sources are generated at fixed positions and orientations relative to the peripheral device such that any change in position and/or orientation of the peripheral device produces a proportional change in the position and/or orientation of the virtual sound sources. Additionally, first order and second order reflected audio paths may be simulated for each virtual sound source to increase the realism of the simulated sources. Each sound path can be produced by modifying the original audio signal using head-related transfer functions (HRTFs) to simulate audio as though it were perceived by the user's left and right ears as coming from each virtual sound source.

Abstract: Techniques and devices are described for generating modified audio signals. The techniques include receiving an audio signal at a device, tracking a movement of the device, generating a first modified audio signal to spatialize the audio signal, generating a second modified audio signal to spatialize the audio signal, causing the first modified audio signal to be rendered using a first speaker of the device, and causing the second modified audio signal to be rendered using a second speaker of the device. In some cases, the first modified audio signal is generated using a first head-related transfer function (HRTF) and the movement of the device, and the second modified audio signal is generated using a second HRTF and the movement of the device, where the second HRTF is different from the first HRTF. Numerous variations and configurations will be apparent in view of this disclosure.

Abstract: A system and method for externalizing sound. The system includes a headphone assembly and a localizer configured to collect information related to a location of the user and of an acoustically reflective surface in the environment. A controller is configured to determine a location of at least one virtual sound source, and generate head related transfer functions that simulate characteristics of sound from the virtual sound source directly to the user and to the user via a reflection by the reflective surface. A signal processing assembly is configured to create one or more output signals by filtering the sound signal respectively with the HRTFs. Each speaker of the headphone assembly is configured to produce sound in accordance with the output signal.

Abstract: An audio system, method, and computer program product which includes a wearable audio device and a mobile peripheral device. Each device is capable of determining its respective absolute or relative position and orientation. Once the relative positions and orientations between the devices are known, virtual sound sources are generated at fixed positions and orientations relative to the peripheral device such that any change in position and/or orientation of the peripheral device produces a proportional change in the position and/or orientation of the virtual sound sources.
