Tesselode has announced the release of Flutterbird, a free VST effect plugin for hosts running under Windows.
Flutterbird is a tool that adds pitch and volume fluctuation to incoming audio. You can use it for traditional wow/flutter effects, as well as more chaotic or extreme modulation.
At its core stay four separate oscillators with adjustable speeds that can be mapped to either pitch or volume.
Flutterbird is available as VST effect plugin (32- and 64-bit) for Windows.
