about

Signal to Noise Loops v4 is a generative data-driven audiovisual piece. It is informed by principles and techniques from the fields of Cybernetics, Sonification, and Artificial Intelligence.

The piece maps data from noise sensors placed around Dublin City to control a generative algorithm that creates the music. Data is mapped to control the sound synthesis algorithms that define the timbre of individual musical voices and data is also mapped to control post-processing effects applied in the piece.

The first movement consists of data recorded from noise level sensors around Dublin in March 2019. This is prior to the COVID-19 pandemic and the bustling nature of the city is well represented. The second movement consists of data recorded in March 2020 when restrictive and social distancing measures were introduced culminating in a full lockdown on March 27th. This section is notably more sedate.

The piece was realized with Python for data handling and mapping, Ableton Live was employed as a sound server to generate musical materials and run a wide range of sound synthesis and post-processing elements. The visuals were designed in Processing with data handling and mapping again carried out in Python.

In 2021 the piece was performed at The New York City Electroacoustic Music Festival, the International Computer Music Conference in Santiago Chile, and Audio Mostly in Trento Italy.
It was installed for S3 of the Video Sound Archive in 2022 and performed at the International Conference on Auditory Display in 2022 where it won the award for Best Artistic Use of Sound in a Sonification at the International Conference on Auditory Display (ICAD) 2022.

You are strongly encouraged to watch the video for this track as this is an audiovisual work. The track bears sonic similarities to Breathing Space and Signal to Noise Loop i++, but is experienced quite differently when presented in the context of the larger audiovisual work.
