PSP Levelizer | Intelligent Automatic Fader Level Control Plugin, Your Transparent and Natural Dynamic Management Tool
Say Goodbye to Manual Automation — Let the Auto-Fader Engine Ride Your Levels with Precision
PSP Levelizer is an advanced Auto-Fader automatic level control plugin from PSPaudioware, featuring an intelligent gain riding engine that maintains consistent audio levels while preserving the original dynamics and musicality. It supports AAX, VST 2, VST 3, and AU plugin formats, compatible with macOS (Intel and Apple Silicon) and Windows platforms, with iLok authorization management allowing activation at 3 locations.
Unlike traditional compressors and limiters that reshape dynamics through continuous gain reduction, PSP Levelizer operates differently: it simulates the behavior of an experienced mixing engineer manually riding the fader, automatically adjusting the signal around a target reference level, or using external Sidechain to make one track's dynamics follow another's signal, opening creative possibilities that traditional dynamic processors cannot achieve. Whether for vocal level riding, bass instrument consistency control, Podcast dialogue leveling, or pre-master level management, PSP Levelizer delivers transparent, natural, and musically pleasing results.

PSP Levelizer Core Technology and Features
-
Auto-Fader Intelligent Gain Riding Engine:PSP Levelizer's core is not a traditional gain reduction circuit, but a highly configurable automatic fader system. It simulates the behavior of engineers manually riding the fader, intelligently tracking and adjusting the signal around a user-defined target reference level, maintaining consistent volume while preserving original dynamic fluctuations and musical expression.
-
Three Response Modes (Sharp / Normal / Smooth):Provides three-stage response characteristic switching. Sharp mode suits fast transient control, such as drum kit or percussion level management; Normal mode balances speed and naturalness, suitable for most vocals and instruments; Smooth mode offers the most gentle and organic gain riding, ideal for scenarios requiring extremely transparent processing like mastering or broadcast.
-
Adjustable Response Time and Action Characteristics:Users can finely tune the fader's response speed and action curve, combined with three response modes, to customize the optimal level control behavior for different audio materials.
-
Multi-Stage Lookahead Preview Processing:Offers multiple Lookahead range options, allowing the processor to react before level changes actually occur, significantly improving processing accuracy. For different application scenarios like live performance, mixing, and mastering, Lookahead settings can be separately optimized for best results.
-
Internal / External Sidechain Operation:Besides internal detection mode, PSP Levelizer supports external Sidechain input, letting one track's level dynamics follow another track's signal. This opens creative applications impossible with traditional compressors, such as making background music automatically follow narration levels, or letting Pad sounds fluctuate with drum rhythm.
-
Sidechain EQ Sidechain Equalizer (Shape EQ + Bell EQ):Built-in flexible sidechain filtering sections including Shape EQ and Bell EQ, allowing the detection circuit to precisely focus on specific frequency ranges. For example, when processing vocals, the detector can ignore low-frequency noise and only judge levels based on the vocal's main frequency range.
-
Intelligent Reference Level Tracking:The system intelligently tracks the target reference level and dynamically adjusts based on the overall trend of the input signal, ensuring levels remain in the ideal range during extended playback.
-
Adjustable Gain Range Limits and Soft Boundaries:Users can set upper and lower limits for gain adjustment and choose to enable Soft Boundaries functionality, making the fader gradually slow down as it approaches limit values, avoiding abrupt gain jumps.
-
High-Quality Brick-Wall Output Limiter:Built-in brick-wall output limiter with adjustable Drive, Ceiling, Release characteristics and stereo linking options, ensuring output signal never exceeds the set maximum level, providing final safety for the entire processing chain.
-
Complete Preset Management System:Built-in comprehensive preset management mechanism, conveniently allowing users to quickly recall, save, and share settings optimized for different application scenarios.
Auto-Fader Engine and Response Modes Explained
- Core operation principle is automatic gain riding (not traditional compressor gain reduction), therefore does not compress dynamic range, only adjusts overall level position
- Sharp mode: Fastest response speed, suitable for processing materials with obvious transients like drum kits, percussion, fast-paced dialogue
- Normal mode: Balances speed and naturalness, the universal first choice for most vocals, guitars, keyboards and other instruments
- Smooth mode: The most gentle gain riding, suitable for scenarios requiring extremely transparent, traceless processing, such as mastering preparation and broadcast program leveling
- Response Timing and Action Characteristics can both be independently adjusted, providing extremely high customization flexibility
Lookahead Preview Processing and Reference Level Tracking
- Provides multiple Lookahead range options, allowing the processor to "see" upcoming level changes and begin adjusting the fader before changes actually occur
- Can be separately optimized for different application scenarios: live performance requires shorter Lookahead to reduce latency; mixing and mastering scenes can use longer Lookahead for more precise level management
- Intelligent Reference Level Tracking can dynamically adjust target levels based on the overall trend of input signals, preventing processing results from deviating due to material's own level drift
- Adjustable gain range upper and lower limits combined with Soft Boundaries option allow the fader to smoothly decelerate as it approaches limits, eliminating abrupt gain jumps
Sidechain Operation and Sidechain EQ Filtering
- Supports both Internal and External Sidechain operation modes
- Internal mode: Detector analyzes the plugin's own input signal, maintaining level near the target reference value
- External mode: Detector receives signal from another track, letting the processed audio track's level dynamics follow the external control signal, achieving creative level-following effects
- Built-in Sidechain EQ consists of Shape EQ and Bell EQ, two independent sections, allowing precise setting of the frequency range the detector focuses on
- Shape EQ provides overall frequency profile shaping, Bell EQ allows enhancement or reduction of specific frequency bands; using both together enables extremely precise detection control
- Typical application: When processing vocals, filter out low-frequency rumble and high-frequency sibilance, letting the detector judge levels only based on vocal fundamental and harmonic ranges
Brick-Wall Output Limiter
- Built-in high-quality brick-wall output limiter serving as the final safety net for the signal chain
- Adjustable Drive: Controls the signal level entering the limiter, determining how aggressively the limiter engages
- Adjustable Ceiling: Sets the absolute maximum output level value, ensuring signal never exceeds the threshold
- Adjustable Release: Controls the speed at which the limiter releases gain reduction after levels drop
- Stereo Linking option: Can choose independent or linked processing for left and right channels; linked mode maintains stereo image stability
Preset Management and Workflow Integration
- Complete preset management system supporting quick recall, saving, renaming, and export sharing of presets
- Applicable to various workflows including Live Sound, Recording, Mixing, and Mastering
- Typical application scenarios include: vocal level riding, Podcast and dialogue leveling, bass instrument consistency control, broadcast and post-production workflows, mixing responsive vocal automation, drum kit and percussion level control, mastering preparation and level management, creative Sidechain-controlled gain automation
