摘要： A method and apparatus processes multi-channel audio by encoding, transmitting or recording “dry” audio tracks or “stems” in synchronous relationship with time-variable metadata controlled by a content producer and representing a desired degree and quality of diffusion. Audio tracks are compressed and transmitted in connection with synchronized metadata representing diffusion and preferably also mix and delay parameters. The separation of audio stems from diffusion metadata facilitates the customization of playback at the receiver, taking into account the characteristics of local playback environment.

摘要： The present invention counterbalances background noise by applying dynamic equalization. A psychoacoustic model representing the perception of masking effects of background noise relative to a desired foreground soundtrack is used to accurately counterbalance background noise. A microphone samples what the listener is hearing and separates the desired soundtrack from the interfering noise. The signal and noise components are analyzed from a psychoacoustic perspective and the soundtrack is equalized such that the frequencies that were originally masked are unmasked. Subsequently, the listener may hear the soundtrack over the noise. Using this process the EQ can continuously adapt to the background noise level without any interaction from the listener and only when required. When the background noise subsides, the EQ adapts back to its original level and the user does not experience unnecessarily high loudness levels.
摘要翻译：本发明通过应用动态均衡来抵消背景噪声。使用表示背景噪声相对于期望的前景音轨的掩蔽效应的感知的心理声学模型来精确地抵消背景噪声。麦克风采样听众听到的内容，并将所需的音轨与干扰噪声分开。信号和噪声分量从心理声学的角度进行分析，并且音轨被均衡，使得最初被屏蔽的频率未被屏蔽。随后，听众可能会听到声音的声音。使用这个过程，EQ可以连续适应背景噪声水平，而不需要听众的任何交互，只有在需要的时候。当背景噪声消失时，EQ适应于其原始水平，并且用户不会遇到不必要的高响度水平。
