Provided are a system and method of mixing a second audio stream with a first audio stream in an audio output device. The system is configured to execute the method, comprising buffering and outputting the first audio stream via the audio output device as unmodified output, determining at least one insertion spot within the first audio stream, modifying the first audio stream at an insertion spotto avoid content loss, outputting the second audio stream at the insertion spot, and resuming unmodified output of the first audio stream at or near a completion of the second audio stream. Modifyingthe first audio stream can include pausing and/or warping the first audio stream at the insertion spot. The audio output device can be a vehicle head unit or a wireless device, such as a mobile phone. 提供了一种在音频输出装置中使第二音频流与第一音频流混合的系统和方法。该系统被配置为执行该方法，该方法包括：缓冲第一音频流并经由音频输出装置输出第一音频流作为未修改输出；确定第一音频流内的至少一个插入点；在插入点处修改第一音频流以避免内容丢失；在插入点处输出第二音频流；以及在第二音频流的完成处或附近恢复第一音频流的未修改输出。修改第一音频流可以包括在插入点处暂停和/或扭曲第一音频流。音频输出装置可以是运载工具头单元或无线装置，诸如移动电话等。
