ValhallaFreqEcho is a free multi fx and delay and echo and time stretcher VST, Audio Unit, RTAS plugin developed by Valhalla DSP. Compatible OS(s): Windows, macOS.
ValhallaFreqEcho is a frequency shifter, combined with an analog-style echo. The MkI release adds a GUI as well as the ability to sync the delay time to the tempo. The sonic results encompass barberpole flanging and phasing, dub echoes that constantly rise or fall in pitch, the classic detuning of frequency shifting, and a variety of psychedelic, evolving self-oscillation patterns that will spin around and through your skull.

- Analog style delay, with delay time set via knob or synced to tempo.
- Low Cut and High Cut filters for shaping delayed sound.
- Feedback control (can produce self oscillation even with no input).
