Abstract: An audio processing and streaming server system includes an input bus, a digital signal processor (DSP), a first and second stream generators. The input bus includes a plurality of input audio channels, each corresponding to a respective input stream of a plurality of input streams, each received at the server from one of a plurality of audio interface devices. The DSP is configured to apply at least one signal chain to at least some of the plurality of input audio channels; and output first and second master audio mixes in accordance with the at least one signal chain. The first stream generator is configured to convey the first master audio mix to the audio interface devices in a first live stream with no added buffering latency, and the second stream generator is configured to buffer and convey the second master audio mix in a second live stream.
