Minute/Year: technical details

The physical hardware that runs the durational installation Minute/Year is as follows: a Raspberry Pi computer, a Xenyx Q802USB mixer, a pair of Behringer C-2 microphones, two Adam F5 monitor speakers, and the required audio and power cables to connect all the elements together.

The room in which it runs has a volume of ca. 200 cubic meters of resonant space. The process of running the daily minute occurs every day at 20:18 throughout the year of 2018. (Likewise, in 2017, it ran each day at 20:17, and in 2016 at 20:16.)

The design of installing the speakers and microphones, and ‘tuning’ the room, is undertaken by us each year. The code that runs the work is originally-coded by us, in collaboration with Kris Slyka, our long-time technical assistant.

The code that runs the work is mostly written in Python and Shellscript. The simpler parts of the code are installed directly on the Raspberrry Pi — this code automatically runs the daily process of playback and recording, and then makes an API call to an AWS server. On the server, each day’s minute of audio is converted into a spectrogram image, and both parts are then combined to create a one-minute-long video, with overlaid title card giving the date and time. These parts (video, audio, image) are then posted, via further API calls, to Vimeo, SoundCloud, Twitter, Tumblr, Telegram, and the daily archive of all minutes to date on our website.
