Post-processing and mixing: Adobe Audition. The CSound raw audio was passed through a 20-band EQ and echo, with some hefty level massaging. A second track was derived from the first, stretching it about 400% in time and lowering the pitch an octave, then adding a flanger effect. A third track was obtained by reversing the second. The three versions were then mixed down to a single stereo track.
More mixing and accompaniment: Propellerhead Reason, where I added a couple of ostinato voices and add’l reverb and echo.
