Description:
This plugin implements a brick-wall limiter with flexible configuration. It prevents input monosignal from raising over the specified Threshold. Additional sidechain inputs are provided for better use.
Attention: this plugin implements set of limiting modes, most of them are iterative. That means that CPU load may be not stable, in other words: the more work should be done, the more CPU resources will be used. Beware from extreme settings.
Controls:
- Bypass - bypass switch, when turned on (led indicator is shining), the plugin bypasses signal.
- Pause - pauses any updates of the limiter graph.
- Clear - clears all graphs.
- Mode - the selected mode to use by limiter:
- Classic - limiter works like compressor with infinite ratio. May cause sound artifacts and clicking on extreme setup.
- Herm Thin, Herm Wide, Herm Tail, Herm Duck - hermite-interpolated cubic functions are used to apply gain reduction.
- Exp Thin, Exp Wide, Exp Tail, Exp Duck - exponent-interpolated functions are used to apply gain reduction.
- Line Thin, Line Wide, Line Tail, Line Duck - linear-interpolated functions are used to apply gain reduction.
- Mixed Herm, Mixed Exp, Mixed Line - classic mode with accurate overloaded peak removal by linear-interpolated, exponent-interpolated and linear-interpolated functions.
- O/S - oversampling mode:
- None - oversampling is not used.
- Half 2x(2L), Half 2x(3L) - 2x Lanczos oversampling of Sidechain signal with 2 or 3 lobes (L) in the kernel.
- Half 3x(2L), Half 3x(3L) - 3x Lanczos oversampling of Sidechain signal with 2 or 3 lobes (L) in the kernel.
- Half 4x(2L), Half 4x(3L) - 4x Lanczos oversampling of Sidechain signal with 2 or 3 lobes (L) in the kernel.
- Half 6x(2L), Half 6x(3L) - 6x Lanczos oversampling of Sidechain signal with 2 or 3 lobes (L) in the kernel.
- Half 8x(2L), Half 8x(3L) - 8x Lanczos oversampling of Sidechain signal with 2 or 3 lobes (L) in the kernel.
- Full 2x(2L), Full 2x(3L) - 2x Lanczos oversampling of Sidechain and Input signal with 2 or 3 lobes (L) in the kernel.
- Full 3x(2L), Full 3x(3L) - 3x Lanczos oversampling of Sidechain and Input signal with 2 or 3 lobes (L) in the kernel.
- Full 4x(2L), Full 4x(3L) - 4x Lanczos oversampling of Sidechain and Input signal with 2 or 3 lobes (L) in the kernel.
- Full 6x(2L), Full 6x(3L) - 6x Lanczos oversampling of Sidechain and Input signal with 2 or 3 lobes (L) in the kernel.
- Full 8x(2L), Full 8x(3L) - 8x Lanczos oversampling of Sidechain and Input signal with 2 or 3 lobes (L) in the kernel.
- Dither - allows to enable dithering for the specified sample bitness.
- SC - enables drawing of sidechain input graph and corresponding level meter.
- Gain - enables drawing of gain amplification line and corresponding amplification meter.
- In - enables drawing of limiter's input signal graph and corresponding level meter.
- Out - enables drawing of limiter's output signal graph and corresponding level meter.
'Limiter' section:
- SC Preamp - sidechain pre-amplification gain.
- Ext - this button enables external sidechain.
- Lookahead - the size of lookahead buffer in milliseconds. Forces the limiter to add the corresponding latency to output signal.
- Threshold - the maximum input level of the signal allowed by limiter.
- Boost - applies corresponding to the Threshold gain to the output signal.
- Attack - the attack time of the limiter. Can not be greater than Lookahead time (greater values are truncated) for some modes.
- Release - the attack time of the limiter. Can not be twice greater than Lookahead time (greater values are truncated) for some modes.
- Knee - additional knee applied to the gain reduction algorithm.
'Signal' section:
- Input - overall input gain.
- Output - overall output gain.
