Abstract: This disclosure describes audio decoding techniques for decoding audio information that needs to be properly clocked. In accordance with this disclosure, the number of audio samples in decoded audio output can be adjusted to compensate for an estimated error the in decoder clock. That is to say, rather than adjust the decoder clock to synchronize the decoder clock to the encoder clock, this disclosure proposes adding or removing audio samples from the decoded audio output in order to ensure that the decoded audio output is properly timed. In this way, the techniques of this disclosure can eliminate the need for an adjustable or controllable clock at the decoding device, which can save cost and/or allow legacy devices that do not include an adjustable or controllable clock to decode and output audio information that needs to be properly clocked.

Abstract translation: 本公开描述了用于解码需要正确计时的音频信息的音频解码技术。 根据本公开，可以调整解码音频输出中的音频样本的数量以补偿解码器时钟中的估计误差。 也就是说，而不是调整解码器时钟以将解码器时钟同步到编码器时钟，本公开提议从解码的音频输出中添加或去除音频样本，以便确保解码的音频输出被正确定时。 以这种方式，本公开的技术可以消除在解码设备处对可调节或可控制的时钟的需要，这可以节省成本和/或允许不包括可调节或可控时钟的传统设备来解码和输出音频信息， 需要正确计时。
