Velvet noise and frequency domain variants of Velvet noise
-- The unexpected emergence of a strange signal forces us to revisit sounds and auditory perception -- Hideki Kawahara (Wakayama Univ.)  EA2019-65 EMM2019-93 |
A sparse and random sequence of 1 and -1 sounds like noise. Moreover, it sounds smoother than white Gaussian noise and c... [more] | EA2019-65 EMM2019-93 pp.69-74 |
