《Selected Ambient Airs》資訊聲音化共創實驗-記錄與呈現

“Selected Ambient Airs” is a project that connects environment, technology and arts by developing an environmental monitoring network and sonification practices. It enables participants to learn about open data, basic electronic circuits and microcontrollers in the methods of “making” and “playing” by applying creative technologies to connect to the Internet, explore data, activate music, and bridge the gap between creative communication and social interaction amongst people.

In an age of co-creation and connection, making and playing appear to be appropriate ways to blur the line between creators and the audience that encourages more people to become creators. Both of them are essential ingredients to establish audience participation while growing the seeds of co-creation. By building on a series of resources created across disciplinary boundaries, we are aiming to connect natural systems, namely those of weather and air quality, with compositional approaches in generative media. A fundamental aspect of this approach is that we are dealing with phenomena which are mostly unseen and which are both scientific and emotional in content.

執行步驟 STEPS

STEP 2 – 創造自己的開放資料 Create Your Own OpenData

利用樹莓派開發的環境感測模組，會將所搜集到的環境資料通過MQTT協定於Node-RED平台上發布。我們將能通過簡單的圖形化介面，把感測模組傳輸的數據創建為自己的資料集並開放給他人使用。換句話說，只要有網路，大家都可以下載本計劃中各節點的環境感測資料，也能依照我們所提供的規格來新增節點。

The environment sensor module gathers data from its environment and publishes over MQTT in Node-RED. Ｗe can create our dataset from those environmental data transmitted from sensor modules and give access to others with a simple GUI interface. In other word, everyone can download the environmental monitoring data with the Internet, as well as contribute a new node according to the provided specifications.

STEP3 – 資料聲音化實驗 Sonification Experiments

「資料聲音化」是將資料以聲音再現的動作。環境感測模組所搜集來的環境數據，經由數位工具輔助對應到不同聲音參數。此一途徑奠基於許多既有系統與資源之上，使用者可自行選擇對應參數的方式，通過多方面交流觀點來促進合作對話。儘管某種程度上，這也是隨機性的展現，因為產出是附加且非刻意的，被觀測者並非有意要傳遞音樂給任何人。但這在概念層面卻很重要，「正在聆聽城市環境狀態」的想法，會改變你我體驗音樂的方式。

We start with the method of sonification that draws on existing resources to connect various systems as the basis to facilitate cooperative conversation and seek a mutual alteration of perspectives through the reflection and interpretation of multifaceted rhythms. Conceptually, mapping numeric data to the parameters of sound is a manifestation of randomness since this music is incidental and unintentional. But this is important at the conceptual level. The idea of “listen to our environment” may change the way we perceive music.

「空氣的聲音」工作坊日期 / Date： 2019/07/06 13:00 – 18:00 地點 / Address：臺北數位藝術中心

本場次與美術學科中心合作，參與者皆為大專院校、高中職教師。工作坊主要分為三個步驟：

1. 利用樹莓派來自製低成本IoT環境感測模組。
2. 將感測器所蒐集到的數據上傳至網路成為開放資料。
3. 利用環境資料來進行資料聲音化實驗。

1. 1. 下載Node.JS來執行Node-RED https://nodejs.org
   2. 可遠端登入樹莓派的VNC https://www.realvnc.com/en/raspberrypi/
   3. 聲音編程軟體SuperCollider https://supercollider.github.io
