ERDUH (El Retorno de una Hormiga) (2019)

ERDUH (El Retorno de una Hormiga) is an audiovisual performance for computer, webcam and projector. The performer records three different sounds on loop, starts an automated process of audio swapping that creates tiny "clip" sounds. At the same time, a similar process is applied in the webcam streaming. After three minutes of that process, the sound turns into noise with reminiscences from the original audios and the video turns into a matrix of points based on the recorded images. FInally, the performer improvises with those sounds and the generative visuals are constantly linked to the sound changes.

Software used: Ableton Live 10, Max/MSP/Jitter 8.

Audio processing

The audio process is designed in Max and it consists in picking two small pieces of different audio buffers and swapping them with each other. This creates two clip sounds (the phase change points) for each swapping. When the process is repeated thousands of times, noise starts filling the waveform. The final result is noise with reminiscences of the original sound.
