Harmonizer

About Harmonize

Harmonize mixes several pitch shifted voices to create interesting harmonies. You can mix up to four pitch shifted voices.

The often experienced "chipmunk" effect which occurs when transposing the human voice or musical instruments can be reduced using the Maintain timbre option. When Maintain timbre is checked, Acoustica creates a smooth spectral envelope estimation of the signal and whitens the signal before pitch shifting. The original smooth spectral envelope is applied after transposing and the original timbre is preserved.
