Dynamically increased noise suppression based on input noise characteristics

Provided is dynamically increased noise suppression based on input noise characteristics. A maximum noise suppression level (Gmin) is not a single constant value for an entire frequency range, but isallowed to vary across frequencies. The amount of variation is dynamically computed based on the input noise characteristics. For example, if there is excess noise in the lower frequency region, the maximum noise suppression level in that region will increase to suppress the noise in that frequency region. This feature can be enabled all the time, and will be active when the input conditions warrant extra noise suppression in a particular frequency region. Thus, the effort involved in manually tuning an audio system (e.g., hands-free telephony, voice-controlled automotive head unit, etc.) canbe significantly reduced or eliminated. 基于输入噪声特性动态增加的噪声抑制。最大噪声抑制电平（）对于整个频率范围不是单个恒定的值，而是被允许跨频率变化。基于输入噪声特性动态地计算变化的量。例如，如果在较低频率区中存在过量噪声，则在该区中的最大噪声抑制电平将增加以抑制在该频率区中的噪声。可以始终使能该特征，并且当输入条件保证在特定频率区中的额外的噪声抑制时该特征将是活跃的。因此，可以显著地减少或消除人工调谐音频
