Hilbert SSB shift applied to full spectrum. L: 0 Hz, R: +Δf Hz. Carrier frequency perceived by the brain = any frequency in the source.
SSB shift applied only within the carrier band. Frequencies outside the band bypass SSB unmodified — HF detail (vocals, treble) preserved.
Best range: 150–400 Hz (≤ 1000 Hz upper limit for effective binaural perception).
Audio plays unchanged. An independent binaural tone layer is added at the output, bypassing SSB. Precise fc/Δf control with no artifact.
