Valhalla Freq Echo

Best for Psychedelic skull-melting chaos

Not necessarily stoned, but beautiful.

Freq Echo is perfect for dub, Dr. Who, and all of your psychedelic needs.

Bode-Style Frequency Shifter + Analog Echo Emulation create surprising sonic effects. Subtle chorusing and double tracking to barberpole phasing and flanging to endless glissandos and runaway echos.

New in 1.2.0: VST3, signed & notarized installers that are ready for Big Sur, signed Windows installer!

New in 1.2.8 (for Mac): Intel/M1/M2/M3 native Mac builds – ready for Sonoma
