Abstract
The invention provides a digital automixer system that includes a master processing unit and at least one non-master processing unit that are interconnected. The non-master processing unit obtains a first microphone signal and determines a first basic level measurement and a network submix audio signal. The master processing unit obtains a second microphone signal and determines a second basic level measurement, and obtains the first basic level measurement and the network submix audio signal from the non-master processing unit. The master processing unit further forms a final mix audio signal from the second microphone signal and the network submix audio signal and determines a gating control signal for the digital automixer system. The master processing unit may also delay the second basic level measurement to compensate for a network delay. The invention also provides a digital automixer system that includes a plurality of master processing units.
