Patent ID: 8644477

Claim:
A digital automixer system, comprising: a first non-master processing unit obtaining a first microphone signal from a first microphone and determining a first basic level measurement (BLM) and a first network submix audio signal by digitally processing the first microphone signal; and a master processing unit obtaining a second microphone signal from a second microphone, determining a second basic level measurement by digitally processing the second microphone signal, obtaining the first basic level measurement and the first network submix audio signal from the first non-master processing unit, forming a final mix audio signal from the second microphone signal and the first network submix audio signal, producing a noise adaptive threshold signal that is indicative of a received microphone signal being above a background noise threshold, and determining a gating control signal for the first microphone from the first basic level measurement, the second basic level measurement, and the noise adaptive threshold signal.
