machine-generated (voss-mccartney algorithm multi-pass implementation in Python) pink noise audio, with digital signal processing applied to enhance the scale of the perceived soundstage in stereo (early reflections, haas effect, reverb, variously modulated at low frequency to impart movement and interest) and add quiet tones detuned in stereo for 'binaural beat' effects
headphones (or like, big-ass klipsch speakers) recommended
