We’ve found 5 free frequency shifter plugins that deserve a spot in your VST folder! Join us as we look at each one!

MFreqShifter

MFreqShifter by MeldaProduction is the first in our list of free frequency shifter plugins. Unlike pitch shifting, which maintains harmonic relationships, frequency shifting alters the pitch linearly across the entire signal, creating atonal and dissonant results. This makes it ideal for creative sound design, especially for experimental or abstract music styles. MFreqShifter is highly versatile, offering precise control over parameters such as shifting amount, modulation, and sidechain capabilities, along with advanced features like mid/side processing and spectral smoothing. 

Frequency Shifter

Frequency Shifter by Kilohearts offers a simple interface with controls for frequency shift amount. Part of the Kilohearts Snapin ecosystem, it integrates smoothly into modular environments, making it accessible for both beginners and advanced sound designers.

Freq Echo

Freq Echo is well-suited for psychedelic effects, dub-style delays, or experimental sound design, creating a wide range of unique sound effects, from subtle modulation to extreme, otherworldly tones. Its straightforward interface includes controls for delay time, shift amount, and feedback, making it easy to use for both novices and professionals. 

Frequency Shifter

The plugin offers straightforward controls for shifting amount, feedback, and mix balance, allowing users to shape the effect easily. As with other Full Bucket Music plugins, Frequency Shifter is optimized for low CPU usage, making it efficient for use in larger projects and live performance setups.

BFS-1

The last in our list of free frequency shifter plugins The BFS-1 by WOK is a virtual recreation of the classic Bode Frequency Shifter, an iconic hardware effect known for its ability to shift audio frequencies linearly, resulting in unique atonal sounds. This plugin offers the same frequency-shifting capabilities, allowing users to create everything from subtle phase effects to extreme metallic and dissonant sounds. It features controls for adjusting the shift amount, feedback, and mix balance, with a vintage-style interface that mimics the original hardware unit. The BFS-1 is designed for sound designers and musicians seeking to add classic analog warmth and experimental textures to their audio productions.
