Exploring Filtering
Neighborhood Sound Lab
Why does a voice behind a wall sound muffled? What changes when you cup your hands over your mouth and speak? Every sound carries a spectrum of frequencies, and a filter decides which ones you hear.
This session presents a general approach to how modular systems alter the frequency spectrum of signals and sounds passing through them. Attendees explore ways in which they can enhance and transform the quality of the sounds they listen to, and the capability of modular systems for expanding their musical ideas about tone and intervals.
¿Por qué una voz detrás de una pared suena apagada? ¿Qué cambia cuando pones las manos alrededor de la boca y hablas? Todo sonido contiene un espectro de frecuencias, y un filtro decide cuáles escuchas.
Esta sesión ofrece un enfoque general sobre cómo los sistemas modulares modifican el espectro de frecuencias de las señales y los sonidos que generan. Los participantes exploran formas de modular y transformar la calidad de los sonidos que escuchan, así como el potencial de estas máquinas para ampliar sus ideas musicales sobre timbre e intervalos.
