One C file → one WAV (the hellsine contract). GOAT = twomass vocal folds as one continuous throat (growl riffs, ~11 Hz bleats, clean verse song); SHARD = chaosfm power chords + melodic frictus glass; girl-robot vosim lead (fem formants, singing envelope, hook/answer/choir phrases). Battery: memkick/implokick/cavikick/wiresnare/gransnare + clickrattle shaker; throatbass = sine sub + formant growl; gongbell FM gongs. Substrate materiality: carved-noise residue bands (pump + whistle risers), tape print story, crunch zone + self-scratch, sidechain pump, eager humanized timing. Classic song form (intro→verse→pre→chorus→ verse→bridge→final chorus→outro), per-family channel-strip EQ, and a first-pass master (HP → smile EQ → 2.5:1 bus comp → glue → -0.5 dBFS).
