Quanta / Signal / Noise variPlay app by Langham Research Centre.

Quanta / Signal / Noise is a new interactive work by Langham Research Centre.

This music presents a shift away from the conventional building blocks of music: melody, rhythm and harmony. Instead there is a focus on sound itself: its unfolding textures, shapes, energies and dynamics.

When using the manual variPlay interface, the piece shifts and changes. Intriguing auditory landscapes can be reconfigured and interchanged. Imaginary places, spaces and narratives unfold. Fluid sound canvases can be brushed, sketched and collaged.

With the automatic variPlay interface, the app itself generates new versions of the piece through algorithmic playback and user control.

This app enables users to create their own versions of a piece that reflects the innovative and inventive work done by avant-garde composers since the middle of the 20th century.

More please!

A lovely design and interface and the sounds were super interesting and I enjoyed fiddling with the knobs and clicking about. I just wish I could have had more tracks to choose from so I’d like more music to play with please.

Interactive electroacoustic music

This is a fascinating app to use - you can manually interact with the Langham Research Centre’s source sounds and recompose your own version of their music. The app itself is very useable, and features an ‘automatic’ mode that allows the algorithm to create its own interpretation of this work.
