Building a SASS (Stereo Ambient Sampling System) using Primo EM172 capsules
Up to now we used a Rode NT4 microphone in a Rycote blimp for stereo field recordings. Since we still had some Primo EM172 microphone capsules lying around we had the idea to build a SASS system.
We found an excellent describtion of how to build it on Vicki Powys’ website caperteebirder.com
We took the measurements and the concept of wiring two EM172 capsules in parallel from her post here: Vicki Powys’ SASS-Lite Narrow
To operate the SASS via XLR cables with 48V phantom power on our Sound Devices 702 we found a manual on the website of Tom Benedict.
Although our implementation of the construction is somewhat unclean due to lack of time and material we are very satisfied with the result. The SASS provides a good stereo image, the mics are very sensive and low noise.
Here are some images of the building process and 2 recordings using the SASS and a SD702 recorder. More investigations will follow.

We contributed a track to the project ‘Each Morning of the World #03 – Central American PhoNographic Mornings #02/1’ by Stephane Marin / www.espaces-sonores.com
„Micro 7“ is the portrait of a morning ritual happening in Santiago de Cuba, in the suburb Micro 7. A seven years old boy, Cesar, receives the symbols of three Orishas, the guerreros, to give him protection and to help him in life.
The ritual happens in the house of his father, the Santero Abelardo Lardué, who is accompanied by a second Santero, taking the part of the Padrino. This is the first initiating ritual starting a long process of further rituals for a person being part of the Santeria community.
During the several phases of the activity the boy will be washed, Chickens and doves will be sacrificed and at the end Cesar gets three necklaces in the colours of the Orishas.
We recorded the material during a long stay in Santiago, when we collaborated with anthropologist Dr. Jose Millet and Abelardo Lardué, developing a number of installations and performances, documenting and portaiing the Santeria community of Santiago de Cuba.
Listen to the live generated ambient music of the A.O.S.C. network in a 24/7 Live Audio Broadcast!
September 22 6pm UTC until September 28 6pm UTC
A.O.S.C. – Agents of Synchronicity is an autonomous system of remote networked machine agents transforming the environmental soundscapes at distant places into a collective realtime composition of abstract electronic music.
A.O.S.C. draws on Anthropocenic notions of the autonomous nature of dispersed environmental events, and their repercussions on the world in which we live.
blackhole-factory sent out 5 microphone agents to international places where they are placed outside their hosts houses to listen to the current soundscape. Each agent streams data of the analysis of the sound spectrum over the internet to a computer in the blackhole-factory studio. An algorithm interpretes these data and calculates parameters to control custom-built audio synthesis software. These parameters are streamed back to the agents where the collective music is generated and can be heard.
actual networked places:
agent02: Lviv, Ukraine – hosted by Ostap Manulyak and Mykhaylo Barabash
agent03: Toronto, Canada – hosted by Rob Cruickshank
agent04: Londrina, Brazil – hosted by Chris Vine
agent05: Sydney, Australia -hosted by Roger Mills
agent06: Bonaforth, Germany – hosted by blackhole-factory
The agents are designed to survive outside in bad weather conditions. They consist of a RaspberryPI single-board computer in a waterproofed box and a custom built microphone.
