KrystalField
Key Features
- Dual downward and upward compression engines let you control peaks and lift quieter detail inside one processor instead of building a multi-plugin dynamics chain.
- Target-based threshold controls plus independent ratio and knee settings for each direction make broad bus or mastering moves easier to tune precisely.
- RMS, Peak, and LOUD detection modes let the processor react to average level, fast transients, or loudness-style behavior depending on the material.
- Auto makeup gain, mix control, bypass, and gain-reduction plus short-term LUFS metering support parallel processing and more honest A/B decisions.
- Lookahead up to 20 ms, low-frequency sidechain bias, and hard or soft clipping add practical final-stage control for mixes that need polish without a full mastering suite.
- The real-time waveform display keeps the dual-compression workflow readable, especially when you are balancing transparent leveling against more assertive density.
Description
KrystalField is a mastering-grade dynamics processor from Krystal Dynamics built around simultaneous downward and upward compression for macOS and Windows. Instead of behaving like a normal compressor with one detector path, it gives each direction its own target threshold, ratio, and knee controls while keeping attack and release unified for faster mix-bus decisions.
That dual-engine design makes it useful when a stereo bus needs both peak restraint and low-level density without stacking several processors. RMS, Peak, and LOUD detection modes, auto makeup gain, mix control, up to 20 ms of lookahead, low-frequency sidechain bias, and hard or soft clipping give it enough range for subtle final polish or more assertive loudness shaping.
The workflow is deliberately visual. BPB's launch coverage calls out the straightforward interface, target-based thresholds, independent upward and downward ratio/knee controls, clipping modes, parallel mix control, and real-time waveform display, which helps KrystalField feel closer to a focused mastering utility than a generic compressor experiment.
As checked on April 29, 2026, KrystalField still clears SSA's permanent-free bar. The official product 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 ZIPs remain public GitHub release downloads with no checkout, signup, coupon, or expiry wording.
Frequently Asked Questions
How is KrystalField different from KrystalComp?
KrystalComp is the more conventional precision compressor, with sidechain routing and EQ as its main strength. KrystalField is built around two simultaneous dynamics engines, so it is better suited to broad bus or mastering moves where you want downward compression and upward compression working together.
What does the upward compression engine do?
The official feature list separates upward and downward processing, with independent target threshold, ratio, and knee controls for each direction. In practice, the upward side is for raising lower-level detail while the downward side controls louder peaks.
Can KrystalField work on individual tracks as well as masters?
Yes, but its feature set is clearly biased toward bus processing, mastering, and final mix polish. The mix control, lookahead, LUFS metering, clipping modes, and dual compression engines make the most sense when you are shaping a group or full stereo signal.
Does KrystalField add latency?
The official technical specifications list latency as variable, depending on lookahead and oversampling. That makes sense for a processor with up to 20 ms of lookahead and oversampling options, so it is better treated as a mixing or mastering insert than a live tracking effect.
Is KrystalField still permanently free right now?
As checked on April 29, 2026, yes. The official page says KrystalField is completely free for personal and commercial use, the Krystal Dynamics homepage says all plugins are provided free of charge, and the public Windows and macOS downloads remain live with no limited-time language.
