Propagate phase

Description

Internal soundgen function called by dPhase(). Propagates phase using the "vocoder done right" algorithm, as in Prusa & Holighaus 2017 "Phase vocoder done right".

Usage

phasePropagate(i, dp_hor, dp_ver, magn, phase_new, tol, bin_width, alpha)

Arguments

i

analyzed frame

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
