Tubeshifter is a free analog-style tube saturation plugin for macOS and Windows, developed by Frostwave Audio. This Nordic company, led by Reidar Schæfer Olsen and Niklas Eurén, is known for creating unique audio tools with innovative designs.
Unlike Frostwave Audio’s darker, mythic-themed plugins, Tubeshifter comes with a bright orange interface and a playful logo. But don’t let the cheerful look fool you—Tubeshifter is built to deliver serious analog warmth and character.
The plugin draws inspiration from vintage tube hardware, recreating the rich, harmonic warmth that producers love in analog equipment. Its simple design includes three intuitive controls:
- Colour: A tilt EQ that shifts the tonal balance. Turn it left for darker, more subdued tones or right for brighter, sharper sounds.
- Drive: Adjusts the intensity of overdrive. From subtle warmth to gritty distortion, this knob shapes the character of the sound.
- Mix: Blends the processed effect with the dry signal, giving you control over how much saturation to apply.
With Tubeshifter, you can breathe life into dull tracks, adding warmth, depth, and even a touch of grit. It’s perfect for anything from subtle enhancement to bold sonic textures.
Frostwave Audio’s ability to innovate while keeping things simple makes Tubeshifter a standout freebie. Available in 64-bit AU and VST3 formats, it’s ready to use on both macOS and Windows.
