What Boost does
The plugin is built around upward limiting, where the focus control moves smoothly from upward brick-wall limiting toward a more conventional treatment. Boost also prevents inter-sample overs, so peaks are kept under control after conversion. The developer lists ultra-low distortion and a transparent character as design goals.
Drive emphasis modes shape the character of the processing, and a mid-side mode allows the stereo image to be manipulated. The plugin is aimed at tracks, groups and master buses where the level needs to increase.
Key features
- Upward focus control. The focus setting moves smoothly between upward brick-wall limiting and a softer behavior.
- Max gain. A max gain control sets how far quiet passages are raised.
- Inter-sample overs prevention. Peaks between samples are kept in check, so the output stays clear of overs.
- Mid-side mode. A mid-side mode lets the mid and side signals be processed for stereo image changes.
- Drive emphasis modes. Drive emphasis modes change the character of the limiting.
- Crack, keygen and serial variants. Searches pair the name with keygen and a working serial key, and a serial key crack is the string most often typed.
