phasePropagate | R Documentation |
Internal soundgen function called by dPhase(). Propagates phase using the "vocoder done right" algorithm, as in Prusa & Holighaus 2017 "Phase vocoder done right".
phasePropagate(i, dp_hor, dp_ver, magn, phase_new, tol, bin_width, alpha)
i |

dp_hor , dp_ver |
time and frequency partical derivatives of phase |
phase_new |
matrix for storing the new phase |
tol |
tolerance of "vocoder done right" algorithm |
bin_width |
width of frequency bin, Hz |
alpha |
stretch factor |
