KrystalPeak
Key Features
- Attack and release controls, including an auto-adaptive release mode, let you shape how quickly the limiter reacts to peaks instead of relying on a one-speed ceiling.
- Left/Right and Mid/Side stereo linking modes make the plugin useful on both conventional stereo material and masters where center-versus-side behavior matters.
- Input and output gain controls pair with bypass and delta monitoring, so you can compare loudness moves and audition only the signal being limited.
- Optional output saturation adds extra density or aggression when a cleaner limiting pass feels too polite for the source.
- Oversampling up to 8x helps support cleaner peak control when the limiter is pushed harder.
- Real-time waveform, input, output, gain-reduction, and short-term LUFS metering make the limiting process visible enough for both learning and practical mix decisions.
Description
KrystalPeak is a transparent digital limiter from Krystal Dynamics for macOS and Windows, built to catch peaks and raise loudness without turning the process into a full mastering-suite session. Its core controls stay direct: input and output gain, attack, release, stereo linking, oversampling, and an optional saturation stage for adding density when clean limiting is not enough.
The strongest part of the plugin is how visual it makes limiting feel. A real-time waveform display, input and output metering, gain-reduction metering, and short-term LUFS readout help connect what you hear with what the limiter is doing to the signal.
That makes KrystalPeak especially useful for producers who want a focused loudness tool that can also teach better limiting decisions. Left/Right and Mid/Side linking, delta monitoring, bypass, performance settings, and multiple themes give it more feedback and control than a basic ceiling-only limiter while keeping the workflow quick.
As checked on May 25, 2026, KrystalPeak clears SSA's permanent-free bar. The official page says it is completely free for personal and commercial use, the Krystal Dynamics homepage says all plugins are provided free of charge, and the Windows and macOS ZIP downloads are public GitHub release files with no checkout, signup, coupon, or expiry wording.
Frequently Asked Questions
Is KrystalPeak mainly a mastering limiter or a mixing tool?
It can work in either role. The official page describes it as a limiter for suppressing peaks and maximizing loudness, while the simple controls and visual feedback make it just as practical on tracks and buses where you need fast peak control.
What does the Delta mode help with?
Delta mode lets you listen to the signal being removed by the limiter. That is useful when you want to hear whether the limiter is only catching stray peaks or starting to shave off important punch and tone.
Why does KrystalPeak include saturation?
The saturation control is optional, so the limiter can stay clean when transparency matters. When you want a denser or more aggressive output stage, it gives you a controlled way to add color without switching to a separate saturator.
What changed in version 1.0.1?
The official version history lists version 1.0.1 as the current release from May 8, 2026. It fixes Mid/Side stereo linking behavior and metering from the early access version.
Is KrystalPeak still permanently free right now?
As checked on May 25, 2026, yes. The official product page says it is completely free for personal and commercial use, and the Krystal Dynamics homepage says all plugins are provided free of charge.
