fedDSP just released SHI, a frequency-focused saturation plugin available free for a limited time on both Windows and macOS. Designed to give producers surgical control over harmonic emphasis, SHI lets you add analog-style presence and weight to specific frequencies—ideal for mixing guitars, drums, synths, vocals, and more. Anyone can grab SHI directly from fedDSP’s official website without a sign-up, and all sounds processed with the plugin are royalty-free.
What Makes SHI Unique?
Unlike classic saturation effects that add harmonics across the spectrum, SHI zeroes in on the frequencies you select, letting you shape your source with next-level precision. This means you can:
- Highlight and saturate only the body or attack of a sound
- Add warmth to lows without harshness in highs (or vice versa)
- Use musical controls to emphasize presence and clarity
- Sculpt overtones for maximum impact in a mix
The interface draws on guitar pedal workflow but isn’t limited to guitar—it’s just as effective on keys, bass, lead sounds, and full groups.
System Requirements & Plugin Formats
SHI supports all major DAWs through these formats:
- VST3 (Windows, macOS)
- AU (macOS)
- AAX (Windows, macOS)
You’ll need a modern system and a DAW that supports 64-bit plugins. No subscription, purchase, or additional software is required.
