Recorded live to disk. Single track cut into 4 pieces then multi tracked. Post effects ( flange, phase, etc ) lightly added. Some animation was applied to mixer ( gain, pan, etc ). Master track compressed and limited before export.
The sounds produced in preparing for the recording session were unlike those that made it onto disk. Don’t know where these came from… oh well, they are here now. Might as well go out of our way to make them feel unwelcome.
