Harmonizer Plugins Buying Guide
What is a harmonizer?
Harmonizer is a kind of pitch shifter that takes the initial signal, duplicates it, and changes its pitch. When the harmonizer is applied to the signal, you can create harmony depending on the interval of the pitch.
Why would you need a harmonizer?
It’s rather hard to find a person who willingly will listen to boring and monotonous music and enjoy this process. That is why we, audio engineers and music producers, like to play with the sound and use various plugins and tools to enhance and make it sound more attractive to the listener. With a harmonizer, you have endless numbers of harmonies that can be created and additional features like modulation or delay can vary the overall result that you want to achieve.
Important features
When choosing a harmonizer plugin, you may want to pay attention to a number of harmonization modes, design, and additional features.
