ERDUH - El Retorno de una Hormiga
for performer, electronics and live video (2019)
Trailer of the piece by Sofía Domínguez and Federico Isasti on February 2025.
ERDUH (El Retorno de una Hormiga) is an audiovisual performance for performer, electronics and live video. The performer records three different sounds on loop and starts an automated process of audio swapping that creates tiny "clip" sounds. At the same time, a similar process is applied to 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.

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 for each swap. When the process is repeated thousands of times, noise starts filling the waveform. The final result is noise with reminiscences of the original sound.First moment: original sounds
