This plugin is a simple tool to prevent ear damage. As soon as there is a peak above 0 dBFS or the specified threshold, the plugin will cut over to playing SOS in Morse code, gradually fading out again when the input returns back to safe levels. The same thing happens if the input contains infinite or NaN values. Made for personal use during plugin development and intense sound design sessions, but maybe you'll find it useful too!
Why not use a regular brickwall peak limiter?
The downside of doing that is that you may end up mixing or doing sound design
into that limiter without realizing it. And at that point, you'll probably need
to either redo part of the process. So this plugin simply gives you a very
non-subtle heads up instead of altering the sound.
You can download the development binaries for Linux, Windows and macOS from the automated builds page. Or if you're not signed in on GitHub, then you can also find the latest nightly build here.
On macOS you may need to disable Gatekeeper as Apple has recently made it more difficult to run unsigned code on macOS.
After installing Rust, you can compile Safety Limiter as follows:
cargo xtask bundle safety_limiter --release
