Abstract: A wireless cellular telephone with an audio codec for converting digital audio signals to analog audio signals. The audio codec comprises two digital audio bus interfaces for coupling to respective digital audio buses, and a digital-only signal path between the two digital audio bus interfaces, such that no analog processing of the audio signals occurs in the digital-only signal path.

Abstract translation: 一种具有用于将数字音频信号转换为模拟音频信号的音频编解码器的无线蜂窝电话。 音频编解码器包括用于耦合到相应的数字音频总线的两个数字音频总线接口和两个数字音频总线接口之间的仅数字信号路径，使得在仅数字信号路径中不发生音频信号的模拟处理。
