The Frequency Shifter is a powerful audio effect plugin compatible with Microsoft Windows and Apple macOS, supporting multiple plugin formats including VST2, VST3, CLAP, AU, and AAX. Developed in native C++ code, it offers precise frequency shifting capabilities up to ±5000 Hz. Users can take advantage of an optional LFO featuring five distinct waveforms and host synchronization, along with four selectable frequency ranges and three mix modes. The plugin also provides flexible control options, allowing linked or individual adjustments for both stereo channels.

Unlike traditional pitch shifters that multiply the frequencies of an input signal, this Frequency Shifter adds or subtracts a fixed number of Hertz to each frequency component. This results in a unique transformation of the audio spectrum, often producing raw, metallic, and inharmonic tones that can add an edgy character to sounds. The effect is also known as Bode Frequency Shifting or Single Sideband Modulation, techniques that are often overlooked but offer distinctive sonic possibilities for creative sound design.

Experimenting with mixing a slightly shifted signal alongside the original input creates unusual phasing effects that can enrich your audio palette. Whether used subtly or aggressively, the Frequency Shifter delivers a broad range of textural modifications that stand out in music production and sound design. Its compatibility across major operating systems and plugin formats ensures seamless integration into various digital audio workstations, making it a valuable tool for producers seeking innovative frequency manipulation.
