The 6 Best Frequency Shifter VST Plugins Of 2021

The 6 Best Frequency Shifter VST Plugins Of 2020 | Integraudio.com

Audio alteration techniques like phasers, pitch shifters, and so on have become a significant part of sound effect generators. However, one interesting take on audio alteration that produces unnatural sounds comes is the frequency shifter. This article discusses frequency shifting and provides you with a list of 6 plugins that we believe are the best frequency shifter plugins.

What Is Frequency Shifter?

Frequency Shifter is a tool that is used to either shift up or shift down the frequency of the incoming signal. This is done by a technique that resembles complex amplitude modulation and pitch shifting.

The difference is that the Frequency shifter does not maintain the harmonic relationships between harmonics and tones of the input signal which makes the sound more unnatural as opposed to pitching shifters. In contrast, frequency shifters can be implemented in an all-analog circuitry, unlike pitch shifters. In recent years, more producers have shown interest in frequency shifters led to many developers emulating them into virtual instruments or plugins.

How does a frequency shifter work?

In a frequency shifter, each frequency is shifted either up or down by a certain level. For example +/- 2 kHz. All the frequencies are moved by the same level which results in broken harmonic relationships. This gives the track a whole new sound. The sound produced is described by many to be comparable to ring modulation.

3. PSP HertzRider Review

More Info & Price (Trial Available)

This simple, straightforward, and easy-to-use plugin by Profession Sound Projects comes with a few exciting tricks up its sleeve.

The interface consists of 2 main knobs:

Left Focal Shift and Right Focal Shift through which you can control the amount by which the frequency of the signal is shifted up or down for either side. Then you have a choice between 3 frequency sweep settings which are either 1 kHz, 3 kHz, or 10 kHz in either direction. By default, the two main knobs are linked together and so their levels are set the same. However, you can control either of them independently using the source switch on top.

Apart from the 2 main knobs, you get the LFO knobs which offer you a choice between 6 different waveforms i.e. sine, square, triangle, a smooth randomizer, saw up, and saw down. Then you have the Rate knob which controls the speed of the oscillator and allows you to set that within the range of 0.1-10 Hz. The Depth knob controls the amount of LFO that is introduced to the signal. The spread knob controls the stereo imaging of this plugin. Finally, you get the Mix knob which controls the Wet/Dry levels, and the Output knob which allows you to set the final gain level.

Key Features:

  • 2 main non-linear knobs controlling the frequency shifting for the left and right focal. They shift in very small increments for high precision
  • LFO control with 6 different waveforms
  • LFO can be synced to match the project tempo
  • Sidechain control to allow for a cleaner mix between the external and internal sources
  • This plugin comes equipped with a good number of presets to help make frequency shifting easier for you

6. Full Bucket’s Frequency Shifter (FREE) Review

More Info & Download

Developed by Full Bucket back in 2012, the Frequency Shifter has garnered some attention for being one of the best frequency shifter plugins. On top of that, it is FREE!

This plugin is easy to use and is small in size. It actually models some classic hardware phaser effects to improve the sound of the string machines.

The interface in this plugin consists of a few control knobs and sliders for you to correctly apply the effect. The first knob on the left is the LFO knob where you can choose from 4 different waveforms which are: triangle, square, saw up, and saw down as well as randomization. Next to it, you get a slider for Rate which sets the oscillation speed. In the center of the interface, you get a knob for frequency range and 2 sliders each for both Minimum and Maximum, Left and Right.

This way you can set the target frequency, set the minimum frequency for both left and right channels, and the maximum frequency for both left and right channels. Finally, on the right side of the interface, you get the Mix slider for L/R which controls the Dry/Wet levels as well as the Volume slider for L/R channels which you can use to set the output gain.

Compatibility:

This plugin requires Windows 7 or higher for PC and OS X 10.7 or higher for Mac. It comes in VST/AU formats and supports both 32 and 64-bit systems.

Summary:

Its price point does not take away from the fact that this is a solid plugin that offers what other paid plugins do and even more.

Conclusion:

Frequency Shifting is an exciting technique that allows you to alter the natural state of the harmonics of your audio. Despite it being introduced in the 1950s, there is still a big room for improvement and it can only get better from here. When it comes to plugins, most plugins offer basic frequency shifting over a selectable choice of frequency bands with the option of LFO in different waveforms.

This makes choosing a plugin an easy choice. If you are looking for industry-quality plugins for a cheaper price, then we recommend opting for either of the MeldaProduction plugins. However, if you are a sound engineer that prefers to have in-depth control and multiple features, then the FRQ Shift by TONSTURM should be your go-to. Finally, if you are a beginner and still haven’t made up your mind on what you require, then we highly recommend you to cop the free Frequency Shifter by Full Bucket.
