Freq Echo
Valhalla Freq Echo takes the familiar warmth of analogue delay and twists it into something far stranger.
Designed by Valhalla DSP, this free plugin fuses a Bode-style frequency shifter with an echo unit, producing surreal modulated spaces and endlessly spiralling feedback tones.
From subtle movement to all-out chaos, it’s the kind of tool that turns a simple signal into an evolving, mind-bending soundscap
System Requirements:
- 64-bit
- VST2/ VST3/ AU/ AAX

Frequency Shifting & Analog Delay
At its core, Freq Echo combines two distinct processes, frequency shifting and delay, in a deceptively simple layout.
The frequency shifter produces harmonic and inharmonic detuning effects, making anything you pass through it feel fluid and alive.
When blended with its tape-style echo, the results range from gentle pitch drift to alien-sounding textures that warp and pulse across the stereo field.
Each element is modelled with Valhalla’s signature attention to warmth and saturation.
It can behave like a subtle modulation unit, a wild resonant feedback loop, or something between a phaser and a flanger, depending on how deep you push the controls.
The delay time can be adjusted manually or synced to your DAW tempo, ensuring everything stays locked in rhythm, even when you’re melting reality.
Psychedelic Feedback & Tonal Control
Freq Echo’s feedback section is where things get truly otherworldly.
By cranking the Feedback knob, you can coax endless, self-oscillating tones that rise, fall, or hover in place, constantly evolving as they echo.
The built-in high and low cut filters let you shape the timbre of those echoes with precision, taming harshness or emphasising warmth to taste.
Despite its trippy potential, the interface remains minimal and intuitive, perfect for fast experimentation.
Whether you’re sculpting dub echoes that stretch into infinity, building cosmic swells, or adding subtle movement to synths, Freq Echo rewards creativity with a sound that feels organic and unpredictable.

FAQ
Yes Fam — it’s 100% free to download directly from Valhalla DSP’s official site, with no registration or activation required.
Definitely. It works beautifully on melodic material like vocals, pads, and leads, adding surreal movement or spacey echo textures.
Unlike a traditional delay that repeats the same tone, Freq Echo shifts the frequency of each repeat, creating constantly evolving motion and pitch drift.
Yes, though with high feedback values it can get loud. It’s best to keep your monitor levels moderate when experimenting with extreme settings.
