Analysis of computational performance and local self-monitoring latency for different operating systems and configurations. All devices were running in the same session, connected to the same local network, using ovbox version 0.21.2, with a Focusrite Scarlett solo USB audio interface and one audio input channel. The column “CPU” denotes the CPU usage as reported by the audio server, which is the average time used to process one audio block divided by the duration of one audio block. Overruns and underruns of the audio device (“xruns”) were counted over a period of 900 s. The monitoring round-trip time (“RTT”) was measured from analogue input to analogue output.
