Final Limit

Final Limit is an audio effects processing plugin. It’s a “limiter” designed to be the final element in your signal chain. It brings the overall volume up, without distorting. (Unless you want a bit of distortion, which it also provides.) I created the plugin using SonicBirth.

How it works

The main slider increases the gain of the input signal which is then processed with a compression algorithm I designed. Any leftover peaks are attenuated using a shaper function curve. There are also options for EQ, attack and release characteristics, and maximum output level.

The user interface is inspired by an old Ensoniq synth I used to own. I avoided naming the limiter’s attack and release characteristics with technical numbers and labels (like milliseconds). Instead the controls are labelled with fun/zany titles like “Dog Slow” and “Burnt Toast.” They sound funny, but the idea is that they actually describe the sound better than a label like “80ms.” The UI was also designed with the idea of minimizing visual feedback. All too often audio engineers make adjustments based on what they see (like the curve of an EQ) instead of what they actually hear.

You can download it here. It runs on OS X as an AudioUnits plugin, but unfortunately it is 32 bit only because sonic birth doesn’t allow exporting 64 bit plugins. It won’t run in hosts that are 64 bit applications.
