istft_mod

Internal soundgen function. Similar to seewave:::istft(), but adapted to work
with time-variable step sizes in the context of dynamic pitch shifting. Only
call it for dynamic istft because the original seewave function should be a
bit faster for static.

internal

Performs parametric synthesis of sounds with harmonic and noise
components such as animal vocalizations or human voice. Also offers tools
for audio manipulation and acoustic analysis, including pitch tracking,
spectral analysis, audio segmentation, pitch and formant shifting, etc.
Includes four interactive web apps for synthesizing and annotating audio,
manually correcting pitch contours, and measuring formant frequencies.
