Flutterbird is a free, open-source audio effect plugin designed to introduce pitch and volume variations to your sound. It specializes in creating natural-sounding wow and flutter effects, commonly used to emulate vintage tape and vinyl characteristics. The plugin also allows for more intense and unpredictable modulation, enabling creative sound manipulation beyond traditional effects.

The plugin features four independent oscillators, each with adjustable speed settings, giving you extensive control over the modulation patterns. These oscillators can be assigned to affect either pitch or volume, allowing for a wide range of dynamic textures and movement in the audio signal. This flexibility makes Flutterbird suitable for subtle enhancements or dramatic sound design applications.

With its straightforward interface and open-source nature, Flutterbird is accessible to both beginners and advanced users. It integrates smoothly into various digital audio workstations, providing a reliable tool for producers and sound designers seeking to add character and motion to their tracks. Its free availability ensures that creative modulation effects are within reach for all levels of music production.
