Abstract: In one embodiment, a device-side audio handling input/output unit (DIO) of a microphone writes audio data generated by the microphone into a ring buffer. A system-side audio handling I/O unit (SIO) receives a request from a software program to consume past audio data from the ring buffer. The SIO provides the past audio data from the ring buffer to the software program. Other embodiments are also described and claimed.

Abstract: Unwanted audio, such as explicit language, may be removed during audio playback. An audio player may identify and remove unwanted audio while playing an audio stream. Unwanted audio may be replaced with alternate audio, such as non-explicit lyrics, a “beep”, or silence. Metadata may be used to describe the location of unwanted audio within an audio stream to enable the removal or replacement of the unwanted audio with alternate audio. An audio player may switch between clean and explicit versions of a recording based on the locations described in the metadata. The metadata, as well as both the clean and explicit versions of the audio data, may be part of a single audio file, or the metadata may be separate from the audio data. Additionally, real-time recognition analysis may be used to identify unwanted audio during audio playback.
Abstract translation: 在音频播放期间，可能会删除不需要的音频，例如显式语言。 音频播放器可以在播放音频流时识别和去除不需要的音频。 不需要的音频可能会被替代音频替代，例如非明确的歌词，“哔”或沉默。 元数据可用于描述音频流中不需要的音频的位置，以便能够用备用音频去除或替换不需要的音频。 音频播放器可以基于元数据中描述的位置在干涉和显式版本的记录之间切换。 元数据以及音频数据的干净和显式版本可以是单个音频文件的一部分，或者元数据可以与音频数据分开。 此外，实时识别分析可用于在音频播放期间识别不需要的音频。

Abstract: A system and method for routing communication to a common audio output device connected to each of two or more audio signal source devices. For each of the two or more audio signal source devices, a set of inputs are assessed. The set of inputs include: an operational state of the audio signal source device, an activity the audio signal source device, an audio-producing application being executed by the audio signal source device, and a degree of user activity with the audio-producing application being executed by the audio signal source. At a point in time, an audio routing score is generated for each of the two or more audio signal source devices according to a weighted calculation of the set of inputs based on the assessing. Finally, an audio signal routing decision is made, to route an audio signal from one of the two or more audio signal source devices to the audio output device, based on the audio routing score for each of the two or more audio signal source devices.

Abstract: In one aspect a device-side audio handling input/output unit (DIO) of a hardware device writes audio data generated by the hardware device within a ring buffer. An input provided by a user for activation of a software program is received, and a notification that the software program is ready to accept the audio data is generated. A system-side audio handling input/output unit (SIO) additionally provides past audio data from the ring buffer to the software program. Other aspects also are described.

Abstract: A centralized resource manager manages the routing of audio or visual information within a device, including a handheld device such as a smartphone. The resource manager evaluates data-driven policies to determine how to route audio or visual information to or from various input or output components connected to the device, including headphones, built-in speakers, microphones, bluetooth headsets, cameras, and so on. Among the data considered in the policies are connection status data, indicating if a device is connected, routing status data, indicating if a device is permitted to route information to or from a component, and grouping data, indicating logical relationships between various components. Components may be considered inherently routable, automatically routable, or optionally routable. Numerous other uses exist for such data, including providing simpler and more logical management interfaces.

Abstract: A system determines to use at least two independent renderers to render at least two output streams that are to be synchronized. The independent renderers are provided with a shared synchronization object when instructed to render the respective output stream. A time when all of the independent renderers can render a respective first buffer of the respective output stream is determined from the shared synchronization object. Rendering of the output streams utilizing the independent renderers is begun at the determined time. In this way, rendering of the output streams may be synchronized.

Abstract: Embodiments of a system that reduces power consumption by power-gating media decoders are described. During operation of the system, a decoder circuit receives encoded audio data and outputs corresponding decoded audio data to a memory, which is electrically coupled to the decoder circuit. Moreover, control logic, which is electrically coupled to the memory and the decoder circuit, provides commands to the memory and the decoder circuit that selectively disable at least a portion of the memory based on an amount of decoded audio data in the memory.
