Abstract: This document describes techniques for synchronizing rendering of multi-channel audio output. First audio data corresponding to a first audio channel and second audio data corresponding to a second audio channel may be received. The first and second audio data may be configured for simultaneous rendering. A transmission schedule for wirelessly transmitting audio data to each of first and second audio rendering devices may be configured, according to which the first audio data may be scheduled for transmission to the first audio rendering device after the second audio data is scheduled for transmission to the second audio rendering device by a first length of time. An indication may be wirelessly transmitted to the second audio rendering device to delay rendering audio data by the first length of time. The first and second audio data may be wirelessly transmitted to the first and second audio rendering devices according to the transmission schedule.
Abstract translation: 本文档描述了用于同步多通道音频输出渲染的技术。 可以接收对应于第一音频频道的第一音频数据和对应于第二音频频道的第二音频数据。 第一和第二音频数据可以被配置用于同时呈现。 可以配置用于将音频数据无线发送到第一和第二音频再现设备中的每一个的传输调度，根据该调度，可以在第二音频数据被调度以传输到第一音频数据之后调度第一音频数据以传输到第一音频再现设备 第二音频再现设备。 可以将指示无线地发送到第二音频呈现设备，以延迟第一时间长度的音频数据。 第一和第二音频数据可以根据传输调度被无线地传输到第一和第二音频再现设备。
