Sound engineer Felix Blume lead an intensive course on working with basic tools for professional work with digital audio. This course focused on recording, editing and mixing techniques, and sound and music reproduction.

The course offered a look at the technical processes used to register sound, to record interviews, to create special effects for radio production and cinema, as well as sound technology used in live events.

A group of 15 from the neighborhood with interests in music and event production, as well as audiovisual media and communication, participated. During the course, they took part in practical exercises and studied sound theory with an emphasis on studio-based work. The group visited a recording studio and a cinema sound mixing studio, which offered participants a window into professional platforms.

The participants had access to a library of books and articles about audio and sound to enhance their learning.

Each participant created a sound project, which ranged from ambient recordings to interviews and soundscapes–all geared towards reflections on significant aspects of the neighborhood. As a conclusion, participants presented their sound projects through an internet radio broadcast from the radio studio at the “Centro de Cultura Digital” (The Center for Digital Culture).
