Live stream on the Locus Sonus open microphone network, intermittent since January 2017. Installed by Julian Weaver (Finetuned), it uses a Raspberry Pi streambox with Cirrus Logic audiocard, running V 3.1 of the streambox software developed by Stef Cousot et al. It includes the live audio streaming software Darkice, an open source project by Ákos Maróy and Rafael Diniz.

Microphones are EM172s with Rycote mini-windjammers, hanging out between the top of the upper sash and window jamb.
