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.

Applications
As a stereo bus processor the device optimises highly complex dynamics, whether on the mix bus or during mastering.

Manage complex dynamic audio with a seamless blend of compression, expansion and saturation that always preserves punch and energy.
Balance tonality and stereo imaging with authentic Variable-Mu and Glue compression in a split-band and mid-side configuration.
Apply pleasant sonic textures and flavours, and refine them using dynamic equalising.

Requirements
Windows VC Redistributable package for Visual Studio 2022 needs to be installed. If it is not yet installed on your system, just download and install it directly from Microsoft.

Not everyone works in a perfectly treated control room. Many mixes are created in bedrooms, home studios or on the go – with limited budgets and imperfect acoustics.

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

Ultra Low Latency Limiter. Ultra low-latency brickwall limiter for artists, producers, mixing/mastering, and broadcast.

Selectable lookahead with 0.5ms, 1ms, and 2ms modes. Low enough for real-time tracking, live streaming, and monitoring without losing your feel.

LOUD for maximum impact, CLEAN for transparency, SMOOTH for glue, and SAFE for zero-artifact peak control. Each with uniquely tuned attack ramps and release behavior.

ADAA (Antiderivative Anti-Aliasing) band-limits the gain envelope to reduce harmonics at the threshold, while 2x/4x oversampling catches inter-sample peaks for cleaner, more accurate limiting.

LUveler is a loudness and dynamics modification plugin compatible with the ITU-R BS.1770 specification. It provides a precise reduction of the dynamics and works as transparently as possible to maintain the sound quality even under heavy use of its compressors and limiters.

This allows a wide range of applications, such as matching dynamic material produced according to the EBU R 128 to a much louder platform. Or the automatic leveling of a podcast. Or simply increasing or decreasing loudness without changing the dynamic range.

High-quality true peak limiters avoid exceeding the maximum level.
The LUveler plugin was developed for the use in an automated environment using the LADSPA API. A VST version for Windows has been added. Porting it to other platforms and operating systems, such as MacOS, is not planned!

Short explanation of the parameters:

Features:
Supported Samplerates: 8 kHz – 192 kHz
Latency: 35.375 ms

APU Spectrum Analyzer is a free spectrum analysis tool supporting a variety of FFT configuration options. You can adjust the FFT window type (Rect, Hann, Hamming, Blackman, Kaiser) and size (from 64 up to 65536) to suit your needs. Monitor spectrum in real-time with variable history size, or load an external file for full spectrum analysis.

Quickly switch between standard dB ranges or auto-range and view the frequency spectrum in log, linear, or note-based scale. Supports histogram hold for measuring long term frequency response. You can also adjust the bucket size independent of the FFT size and take snapshots of the frequency response for reference.

We’re picking up right where we left off!

No signal smearing! No stereo narrowing! No spectral shifts or transient loss! Because at the heart of this plugin lies an ultra-transparent philosophy. It tends to deliver much higher loudness compared to its competitors— but it does so in a very different way, without sacrificing that sought-after analog feel.

And best of all: it does this without making you feel the difference between the original and the processed signal.

The plugins remain free —support the developer if you can.
