getDom

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.
