    摘要: A headphone for spatial audio rendering includes a first database having an impulse response pair corresponding to a reference speaker location. A head sensor provides head orientation information to a second database having rotation filters, the filters corresponding to different azimuth and elevation positions relative to the reference speaker location. A digital signal processor combines the rotation filters with the impulse response pair to generate an output binaural audio signal to transducers of the headphone. Efficiencies in creating impulse response or HRTF databases are achieved by sampling the impulse response less frequently than in conventional methods. This sampling at coarser intervals reduces the number of data measurements required to generate a spherical grid and reduces the time involved in capturing the impulse responses. Impulse responses for data points falling between the sampled data points are generated by interpolating in the frequency domain.

    摘要: Systems and techniques are provided to transmit data over a digital interface between a sender and a receiver. The digital interface is configured for transmitting a primary type of data as opposed to a secondary type of data. Nevertheless, systems and techniques are provided where the secondary type of data can be transmitted in the digital interface. As such, the primary and/or secondary types of data are transmitted from the sender to the receiver via the digital interface. The primary and secondary types of data may be different and/or unrelated and could be any type of data including, but not limited to, audio data, general data, and bulk data. Yet, the received primary and secondary types of data are still useful after the transmission.

    摘要: A computer sound card includes a power supply noise isolation circuit for reducing ground plane noise generated during application of heavy electrical loads to the power supply, such as loads presented by computer GPUs. The power supply isolation circuit isolates the output ground from the ground presented from the power supply to the isolation circuit input. The isolation circuit in one embodiment includes switching circuitry and a transformer to reduce the power supply ripple noise that might otherwise be introduced by the power supply into an amplifier such as a microphone preamp. In some embodiments a differential amplifier stage is added to the output of the microphone preamp stage to further reduce noise, such as common mode noise.

    摘要: It is common that in an audio system, there are multiple data rates that need to be synchronized. For example, a sending device has its own crystal or clock, and a receiving device has another. Typical solutions introduce a lot of latency. According to various embodiments of the invention, a data management mechanism and technique are presented. The data management mechanism and technique pertains to managing media data such as those in an audio system, for example, managing the consumption of digital audio data in USB audio. The data management mechanism may include a dynamic buffer, which can be automatically controlled and adjusted to address issues (e.g., latency) in data consumption.
