FedDSP has released SHI, a new saturation plugin available as a free download for a limited time. After the promotion ends, the plugin will increase to $30.00, with the reduced price available until March 31, 2026.
Frequency-Dependent Saturation for Targeted Tone Shaping
SHI is designed as a frequency-dependent saturation plugin that allows users to add harmonic character to a selected part of the spectrum rather than processing the full signal equally. This gives users a more focused way to shape tone, whether the goal is to add more weight to the low end, more body to the mids, or more edge to the highs.
Instead of washing the whole signal in saturation, SHI is built to make distortion feel more deliberate and mix-aware. The result is a sharper and more controlled sound that can be tailored to the exact area that needs more presence or excitement.
Built for Flexible Use Across a Mix
FedDSP positions SHI as a compact but versatile tool that can be used on a wide range of sources. It can add bloom and size to bass-heavy material, bring more knock and body to midrange content, or increase articulation and attack in the upper frequencies.
The plugin can also be used to energize guitar signals, add more impact to drums, bring extra weight to bass parts, and add movement and life to loops and samples. That makes it a practical option for anyone looking for targeted saturation without adding unnecessary processing to the rest of the signal.
Lightweight Workflow With No Extra Hassle
SHI is built for fast and simple use in modern sessions. FedDSP states that the plugin runs with zero latency, supports offline-ready licensing, and allows up to three simultaneous activations per user. It is also compatible with major DAWs and operating systems, including Apple Silicon systems.
The company also highlights a friction-free setup with no iLok requirement, no dongles, and no need for a constant internet connection.
