I generated a square tone with audacity and applied a few effects to it, mostly wahwah i think, and faded in and out. If you repeat it, it makes a very believable sound for an old video game machine.
This is a free sound design. Sound picture of a room with machines. A sound experiment with samples that were created previously in different ways and ways, as well as samples created for this piece. A lot of granular synthesis and filtration, equalization and convolutional reverb.
When my band was allowed to record after-hours in an industrial space in west oakland, i took the opportunity to show up early to record some of the machines in action. This is a recording of an industrial embroidery machine as it sews on logos to eight sweatshirts. Unfortunately my recording of the glass etching machine in another part of the building didn't turn out as useful--it sounded pretty crazy.
