# Wave Shifter

***

### Overview

Wave Shifter offers frequency shifting, ring modulation, and amp modulation effects that modulate the input signal, generating new harmonics and inharmonic sidebands. It includes controls typically found in synthesizers, such as FM and soft sync, enabling the creation of unique harmonic distortion effects. The built-in modulation can produce classic sweeping effects, rhythmic movement, and even random modulation.

Both the standalone plugin and effect rack versions include presets that range from lush ambiance to spatial sound effects.

### 1. Frequency & FM Controls&#x20;

**Frequency.** Set the frequency of the internal oscillator based on the current **Style** setting. For frequency shifting, you’ll get clear positive or negative shifts. With ring mod and amp mod, the internal oscillator will start cycling backward when negative.

**Frequency Mode.** Select the range of the **Frequency** knob.

* **Fast.** Audio rate frequency settings in Hz.
* **Tuned.** Set the frequency using MIDI notes.
* **Slow.** Low frequency settings in Hz.
* **BPM:** Set the frequency using BPM synced values.

**Soft Sync.** When active, the internal oscillator responds to the input signal’s polarity, creating unique harmonic distortion, especially at higher **Frequency** settings.

**Stereo.** Adjust the stereo phase offset of the internal oscillators. This effect is particularly noticeable with slower **Frequency** settings.

**Spread.** Adjust the relative frequencies of the internal oscillators to create stereo shifting effects. Positive values gradually increase the right frequency and lower the left frequency. Negative values have the opposite effect.

**FM Source.** Select a signal that will be used to modulate the internal oscillator's frequency. These options included different oscillator types, noise, and the input or output signals.&#x20;

* Note, if you select '**Extern**' as the **FM Source**, ensure that the **Sidechain input** is properly configured in your DAW for this function to work correctly.

**FM Ratio.** Adjust the FM SOURCE frequency as a ratio of the current FREQUENCY setting.

**FM Filter.** Adjust the amount of low-pass filtering applied to the **FM Source**.

**FM Amount.** Set the amount of frequency modulation applied to the internal oscillators.&#x20;

### 2. Display Controls

**Style:**

* **Freq Shift.** Adds or subtracts frequencies equally across the spectrum.
* **Ring Mod.** Multiplies the input signal with an internal oscillator, generating sidebands above and below the input frequency, while removing the original signal.
* **Amp Mod.** Similar to RING MOD, but retains the original signal.

**Stereo Mode.** Choose between Stereo and Mid-Side modes.

### 3. Modulation

**Modulation Depth.** Adjust the amount of internal modulation that is applied to the phaser. Setting this to 0% will enable manual control over the modulated parameters.

**Rate.** Adjust the LFO rate.

**Rate Sync.** Enable BPM sync for the LFO rate.

**Shape Snap.** Enable snapping between LFO shapes. When disabled, the LFO shapes are continuously morphed.

**LFO Shape.** Choose from sine, triangle, downward ramp, or square LFO shapes. With **Snap** off, these shapes can be continuously morphed.

**LFO Randomize.** Adjust the amount of LFO randomization. Note that each waveform randomizes in a unique way.&#x20;

**Stereo Randomize.** When active, separate randomization will be applied to each of the LFO's stereo channels, resulting in a wider effect.
