The castrated oboe is Delia's name for a sound she created by recording her own voice at different pitches, splicing together a melody from fragments, high-pass filtering and adding reverberation.
Delia has since referred to [Blue Veils and Golden Sands] as including her "castrated oboe", but the only non-electronic source really recorded is her voice, cut up and re-pieced.
- Original recording of Delia's voice
- Fragments of different pitches of voice spliced into the Blue Veils melody
