摘要： This disclosure describes circuit configurations that may be used for active noise cancellation in the digital domain. In particular, this disclosure proposes the use a down sample unit and an up sample unit, rather than memory based delay circuits, to achieve one or more desired delays in digital adaptive noise cancellation circuits or other circuits that use delay for signal processing. The delay achieved by the down sample unit and the up sample unit may be tunable so as to allow flexibility in producing the necessary delay for different active noise cancellation circuit configurations. Many different adaptive noise cancellation circuit configurations are discussed, and the techniques may also be useful for other types of circuits, such as low-latency equalization circuits.
摘要翻译：本公开描述了可用于数字域中的主动噪声消除的电路配置。特别地，本公开提出使用下采样单元和上采样单元而不是基于存储器的延迟电路来实现使用延迟进行信号处理的数字自适应噪声消除电路或其他电路中的一个或多个期望的延迟。下采样单元和上采样单元实现的延迟可以是可调谐的，以便允许灵活地为不同的有源噪声消除电路配置产生必要的延迟。讨论了许多不同的自适应噪声消除电路配置，并且这些技术也可以用于其他类型的电路，例如低延迟均衡电路。

摘要： A headset device (100) includes a first earpiece (108) configured to receive a reference sound and to generate a first reference audio signal (111) based on the reference sound. The headset device (100) further includes a second earpiece (118) configured to receive the reference sound and to generate a second reference audio signal (121) based on the reference sound. The headset device (100) further includes a controller (102) coupled to the first earpiece (108) and to the second earpiece (118). The controller (102) is configured to generate a first signal (107) and a second signal (117) based on a phase relationship between the first reference audio signal (111) and the second reference audio signal (121). The controller (102) is further configured to output the first signal (107) to the first earpiece (108) and output the second signal (117) to the second earpiece (118).

摘要： Techniques are described for assisting near distance communications. A first device comprising a receiver, a sensor and a processor may be configured to perform the assisted near distance communication techniques. The receiver may receive, from a second device located within a conversational distance to the first device, monophonic audio data representative of the near distance communication. The sensor may generate a sensor signal representative of spatial information of the near distance communication. The processor may render, based on the spatial information and the monophonic audio data, multi-dimensional audio data in which the near distance communication originates in a soundfield from a location of the second device relative to the first device. The processor may next output the multi-dimensional audio data to a transducer so as to reproduce the near distance communication in multiple dimensions.
