Fehrenberg Audio DynCurve is a curve-based dynamics processor for Windows that fundamentally reimagines how compression and expansion work. Instead of the traditional approach of setting a threshold, ratio, and knee, DynCurve gives you a freely editable transfer curve — input level on the X-axis, output level on the Y-axis — so you can draw exactly how your signal responds across its entire dynamic range. Compression, expansion, gating, and gain shaping can all exist simultaneously on the same curve, from subtle leveling to extreme creative waveshaping. DynCurve features independent Mid and Side curves, a dual release architecture, RMS blend detection, oversampling, asymmetric envelope mode, a GPU-accelerated responsive UI, and full multichannel surround support with Mid/Side processing across immersive buses. Available as VST3 and AAX for Windows. A 14-day free trial is available with no account needed — just download and click the trial button.

The Core Concept — Curve-Based Dynamics
Every traditional compressor presents you with three numbers: a threshold, a ratio, and a knee. These three values together describe a transfer function — the relationship between input and output level. DynCurve makes that transfer function visible and directly editable. Rather than adjusting abstract parameters that indirectly define the curve shape, you draw the curve itself. Want a gentle compression region that transitions into hard limiting at the top? Draw it. Want upward compression for quiet passages combined with downward compression for loud ones? Draw it. Want the exact behavior of a vintage compressor you know by ear? Approximate its shape and refine from there. The curve editor displays both spline and linear segment modes, with a Magnetic Diagonal (Shift key) that snaps to the 1:1 ratio line, a Curve Ruler for reading exact input/output levels at any point, and a zoomable view for precision editing on Windows.
Key Features
📈
Freely Editable Transfer Curve
Compression + Expansion + Gating on one curve
Draw the entire transfer function directly — compression, expansion, gating, and gain shaping can all live on the same continuous curve. Spline and linear segment modes. Shift-snap to 1:1 diagonal. Curve Ruler shows exact input/output levels per point on Windows.
↔️
Independent Mid / Side Curves
Stereo · Mid · Side — each with own curve
Instant access to Stereo, Mid, and Side processing, each with its own independent transfer curve. Shape the center and sides differently, control width through dynamics, and move between perspectives without duplicating plugins on Windows.
⏱️
Dual Release Architecture
Two independent release times — blend between them
Two independent release times work together simultaneously. Blending between them allows fast local recovery without sacrificing long-term smoothness — responsive without sounding nervous, dense without pumping on Windows.
⚡
Snappy + Relaxed Attack Modes
Character control beyond just attack time
Snappy mode emphasizes the initial rise of the envelope for pronounced transients and punchy drums. Relaxed mode behaves like a classic smooth attack for vocals, sustained instruments, and transparent leveling on Windows.
📊
RMS Detection Blend
Blend peak + energy-based detection continuously
RMS Time and RMS Mix controls let you blend energy-based envelope detection into the control signal continuously — rather than committing to a fixed mode. Especially effective for vocals, bass, pads, and bus compression on Windows.
🔊
Oversampling
Reduces aliasing at fast attack/release settings
Processes at a higher internal sample rate to handle frequencies above the Nyquist limit accurately before converting back. Cleaner transients, smoother high-frequency response, reduced harshness at aggressive settings on Windows.
〰️
Asymmetric Envelope Mode
Separate followers for positive + negative halves
Uses separate envelope followers for positive and negative waveform halves — introducing subtle nonlinear behavior comparable to analog saturation asymmetry. Ranges from gentle coloration to pronounced distortion-like character on Windows.
🌐
Multichannel Surround Support
Mid/Side dynamics on surround + immersive buses
Interprets every multichannel format as a coherent stereo soundstage. Groups stereo pairs into a shared spatial image and derives a global Mid/Side signal — enabling Mid/Side dynamics on surround and immersive buses on Windows.
🖥️
GPU-Accelerated UI
Responsive, zoomable, real-time visualization
GPU-accelerated interface keeps the curve editor and envelope history display smooth and responsive at all times. Zoomable curve editor and envelope display for precise work at both fine and extreme settings on Windows.
⚖️
Auto Gain + Level Match
True Peak and RMS delta matching
Auto Gain estimates compensation from the curve shape. Level Match continuously measures input/output difference with separate Delta TP and Delta RMS readouts — each with its own Match button to align levels instantly on Windows.
🔀
Wet / Dry Mix
Parallel processing — non-uniform blend
The Wet/Dry blend is non-uniform — larger gain changes are smoothed more strongly than smaller ones. Strong peaks and deep reductions are restrained while fine dynamic detail is preserved, for natural parallel compression on Windows.

Sidechain Controls
SC Source — Internal / External
Choose whether the control signal is derived from the plugin’s own input or from an external sidechain signal on Windows.
SC Low Cut — HPF on control signal
High-pass filter on the sidechain signal reduces low-frequency dominance — essential for mix bus, drums, and full-range material on Windows.
SC Trim — Control signal level
Adjust the sidechain signal level to move it into a useful operating range or drive an existing curve harder or more gently on Windows.
Stereo Link — 0% to 100%
0% = channels measured independently. 100% = both channels share the same control signal. Intermediate values blend stereo stability with independent channel behavior on Windows.
Mid → Side Routing
Reroutes the Side sidechain to be driven by the Mid signal — enables unconventional spatial effects and creative dynamic width control on Windows.
Center / LFE → SC (Surround)
Includes or excludes Center and LFE channels from the detector signal on multichannel tracks — prevents dialogue peaks or LFE sub-bass from triggering the entire mix on Windows.

How is curve-based compression different from traditional compression? ▾
A traditional compressor uses three parameters — threshold, ratio, and knee — that together define a transfer function, which is the mathematical relationship between input and output level. You adjust these abstract numbers and the compressor applies the resulting curve to your signal. DynCurve eliminates this layer of abstraction entirely. Instead of adjusting parameters that indirectly define the curve shape, you draw the transfer curve directly in a visual editor on Windows. This means you can create any combination of behaviors on a single curve: gentle upward compression for quiet passages transitioning into hard downward compression at loud levels, followed by an expansion zone at the top — all visible, all editable, and all active simultaneously. You also see the real-time envelope signal overlaid on the curve editor, so you can position the curve exactly where the dynamic movement of your audio actually occurs.
What does the dual release architecture do in DynCurve? ▾
DynCurve’s dual release architecture uses two independent release time constants working simultaneously. By blending between them with a single control, you can have a short release time for fast local recovery from transients and a longer release time for smooth long-term envelope behavior — both active at the same time. This solves one of the fundamental tensions in compressor design on Windows: a fast release makes a compressor sound responsive but can cause pumping and nervousness, while a slow release sounds smooth but may not recover fast enough between closely spaced transients. The dual release blend lets you achieve fast and smooth simultaneously, resulting in a compressor that feels responsive without sounding nervous and dense without pumping. Additionally, the release curve can be set to Logarithmic (dB domain — more musical, more transparent) or Linear (linear value domain — punchier, more immediate for rhythmic material).
