A powerful and flexible spectrum analyzer for modern audio production.

Mid/Side · Left/Right · Transient/Tone
Multiple analysis modes in one view.

Component monitoring
Isolate and track signal components.

Sidechain comparison
Compare main and reference signals.

Goniometer & correlation
Phase and stereo field visualization.

Oscilloscope
Real-time waveform visualization.

From sound design to mixing and mastering — gFractor gives you precise visual feedback and deep insight into your audio at every stage of the workflow.

Switch between Mid/Side, Left/Right, and Transient/Tone analysis to explore your signal from any angle. Monitor individual components — isolate transients from tonal content, or hear the mid and side channels in complete separation.

Visually compare your main signal against a sidechain reference — instantly revealing spectral relationships between tracks. Swap main and sidechain with a single key press for rapid A/B analysis without breaking your flow.

Comprehensive stereo visualization in one place: a goniometer for phase and imaging, a correlation meter for mono compatibility, and stereo width broken down per octave — so you know exactly where your width is coming from and where it isn’t.

Capture any Peak Hold curve as a reusable target and save it to a file. Load it back in any session to compare against your current track — perfect for matching tonal balance across mixes or checking a master against a reference.

Molotok, a simplified version of TDR Molot GE, is a musically characterful dynamics processor. Meaning “Small Hammer” in Russian, Molotok provides a rich range of exciting compression colors at your fingertips.

While Molotok doesn’t emulate any “vintage” device, its sound and behaviour was definitely inspired by their most interesting musical peculiarities. This flexibility makes it a rewarding choice for almost any source in the mix, be it drums needing more crisp and impact, solidification and enrichment of vocals, or the enhancement of guitar and bass recordings of all types.

Molotok relies on the same algorithms as its larger edition, Molot GE. As with all TDR plugins, Molotok employs state of the art audio processing technology keeping unwanted distortion under strict control. An intuitive and well documented user interface offers quick access to all relevant parameters in a rewarding manner. Several helpers such as unlimited undo/redo, optional stepped controls, inline help tips and many more features help the operator achieve consistent results within a short time.

Notable Features
– Full featured dynamics compressor
– Eleven musically intriguing compression flavour nuances
– Different quality modes including zero-latency operation
– High quality signal processing

System requirements
Win 7 or above, Mac OS X 10.9 or above. OpenGL support.

A darker, Polarity-modified version of Robbert van der Helm’s Spectral Compressor: per-bin upward and downward compression, pink-noise shaping, sidechain spectral matching, freeze, and IR export.

Main Input
The dry signal is captured for latency-compensated mix, bypass, match, and delta monitoring before the spectral processor runs.

FFT Compressor
The signal is windowed, transformed into FFT bins, shaped by the upward/downward compressor bank, then rebuilt with overlap-add processing.

Sidechain + Output
Optional sidechain analysis can drive matching or compression. Freeze can lock the current curve, IR export can save it, and output gain/match finish the comparison.

Vocal Pitch Corrector. Most vocal tuners make you choose. You can sound perfectly in tune, or you can sound human. PitchCure gives you both.

It is a high-end vocal tuner. Some plugins turn real singing into robot sounds. PitchCure does not do this. It tracks the voice and keeps the real feeling safe. Words stay crisp. Breaths stay natural. The tuning feels subtle and natural.

It is built for fast work. You do not have to draw lines on a screen. Find your key with one click. Pick your voice range. Then, turn the main knobs.

Use Speed to fix bad notes. Turn up Humanize to keep the song’s emotion. Use Transition for smooth slides between notes. Use the Color knob to add rich tone.

You might want hidden tuning for a quiet song. You might want fast tracking in the vocal booth. Or, you might want vocals locked to your MIDI chords. PitchCure gives you great pitch that still sounds human.

Features:
– Transparent Tuning: Artifact-free, time-domain pitch shifting without metallic phase-smearing.
– Vibrato Protection: The Humanize engine actively maps and preserves natural vibrato and emotional expression.
– Fluid Transitions: Control the glide between notes—from instant hard-snaps to smooth, natural portamento.
– Auto Key & Custom Scales: One-click key detection, or build your own scales using the interactive Edit Notes matrix.
– MIDI Target: Override the scale and force the vocal to follow the exact chords or melodies you play on your keyboard.
– One-Knob Color EQ: A built-in tilt EQ to instantly add chest warmth (Dark) or brilliant air (Bright).
– Live Tracking Ready: Near-zero latency in Real Time mode, or switch to HQ for maximum processing quality during mixdown.
– Ultra-Light CPU: Highly optimized to run at low CPU, easily handling massive multi-vocal sessions.

TDR Kotelnikov is a wideband dynamics processor combining high fidelity dynamic range control with deep musical flexibility. As a descendant of the venerable TDR Feedback Compressor product family, Kotelnikov has directly inherited several unique features such as a proven control scheme, individual release control for peak and RMS content, an intuitive user interface, and powerful, state of the art, high-precision algorithms.

With a sonic signature best described as “stealthy”, Kotelnikov has the ability to manipulate the dynamic range by dramatic amounts, while carefully preserving the original tone, timbre and punch of a musical signal. As such, it is perfectly suited to stereo bus compression as well as other critical applications.

The concept is “proudly digital” in the sense that it doesn’t try to emulate any previously existing device. This is the original!

Key specs and features
– 64bit multi-rate processing structure for highest accuracy
– “Delta” oversampled signal path (bit transparent at 0dB gain reduction)
– Super fast, yet natural sounding compression
– “Crest factor” based control scheme offering independent release controls for peak and RMS events
– Flexible sidechain highpass filter
– Advanced stereo linking options optimized for the stereo bus
– Delta preview mode previews the difference between compressed and original signal
– Latency compensated, click free bypass (i.e. processing never interrupted)
– User interface rescaling (100%, 125%, 150%)

System requirements
Win 7 or above, Mac OS X 10.9 or above. OpenGL support.

FeenstaubHDR – High Dynamic Range Stereo Bus Processor

At a Glance
Mixing music is essentially about adjusting and balancing audio in three dimensions: Its timbre, its dynamic structure and its appearance in the stereo field. The FeenstaubHDR audio plugin takes advantage of effects in all three dimensions that add up to a very consistent, pleasant and musical-sounding finishing. It works best on complex full program stereo material but also shines on vocals, single instruments as well as the drum bus.

KNOCK Clipper is a premium quality, user adjustable hard & soft clipper designed by DECAP. It is the CLIP module from his acclaimed plugin, KNOCK. It is inspired by the signature sound of his popular drum kit series DRUMS THAT KNOCK, which has helped shaped the sonics of modern music.

Push your drums hard without ever going above 0db to give your drums a warm, aggressive tone reminiscent of pushing vintage analogue gear into “the red”. Select a harder clip curve for a more aggressive tone, or a softer clip curve for a rounder tone. KNOCK Clipper has an optional high quality mode to enable oversampling.

-Exact clipper from DECAP’s acclaimed plugin, KNOCK
-User adjustable hard / soft clipper
-Lightweight on the cpu
-Easy to use
-Never go above 0db
