Audio systems, methods, and computer readable media for managing audio headroom are provided. At least two input signals are received and combined. The combined signals is compared to a threshold value and may be adjusted if the combined signal exceeds the threshold value. A gain is applied to the first input signal based upon the combined signal being above the threshold value. The gain may be an attenuating gain. Accordingly, a gain is applied to at least one input signal to reduce the input signal when a combination of the input signals exceeds a threshold value.
