Digital Microphone Automixer

A digital automixer system, comprising:

• a first 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;
• a second master processing unit obtaining a second microphone signal from a second microphone and determining a second basic level measurement (BLM) and a second network submix audio signal by digitally processing the second microphone signal;
• the first master processing unit determining a first gating control signal from the first microphone signal and the second basic level measurement to control the first microphone signal and forming a final submix audio signal from the second network submix audio signal and the first microphone signal;
• and
• the second master processing unit determining a second gating control signal from the second microphone signal and the first basic level measurement to control the second microphone signal, and essentially forming the final submix audio signal from the first network submix audio signal and the second microphone signal.

A method for supporting audio conferencing with a plurality of microphone, comprising:

• (a) obtaining, by a first unit, a first microphone signal from a first microphone;
• (b) determining, by the first unit, a first basic level measurement (BLM) and a first network submix audio signal by digitally processing the first microphone signal;
• (c) obtaining, by a second unit, a second microphone signal from a second microphone;
• (d) determining, by the second unit, a second basic level measurement by digitally processing the second microphone signal;
• (e) forming, by the second unit, a final mix audio signal from the second microphone signal and the first network submix audio signal;
• (f) determining, by the second unit, a gating control signal from the first basic level measurement and the second basic level measurement;
• and
• (g) forming, by the first unit, the first network submix audio signal using the gating control signal.
