StupidCompressor by SNFK Music is a Virtual Effect Audio Plugin for Windows. It functions as a VST Plugin.
This plugin isn’t meant to be tweaked for hours – it’s designed with the set-and-forget mentality. StupidCompressor is designed to be stupid easy to use. It contains classic controls as well as some advanced features in the advanced panel for more control on your sound. StupidCompressor is open source in the hope that it will help other developers in their own development and that other developers can help make StupidCompressor even better.
Full Feature List

What is it?
This tube preamp emulation has been developed Philipp Bulling as a thesis work. Philipp has been offering the plugin in VST format for some time on his own website. He has now moved on to new areas for some time already but didn’t want to let down his users. Hence, DDMF took over the code and will continue to offer the plugin as freeware, with the intent to further improve it and maybe add some more bells and whistles in the future.
The plugin is very unique in the sense that it gives you full control over all aspects of the modelled circuit. All values of all the capacitors, resistors etc. can be tuned by the user. Here is what Philipp had written on the original page.
AbstractSince the sound of an analogue tube amplifier has always exerted a strong fascination, electrical circuits with tubes play a certain role in the world of audio engineering up to now. On the other hand, audio technology becomes more and more digitised. In many cases, digital models emulate real devices in such a way that differences in sound are hardly audible. In this work a model is developed which is able to emulate the typical sound of a tube amplifier on digital devices. Here the main focus is on preamplifiers with triodes, since they have a particular influence to the sound.
Based on the physical properties of real tubes, a tube model is developed first. This mathematical model includes results of theoretical studies as well as analysis of data sheets. The model is then used to implement an entire amplifier circuit. In addition to the tube itself amplifier circuits contain several passive elements. In the domain of digital signal processing the latter are described by finite difference equations, which are solved recursively.
The resulting algorithm is finally implemented as an audio plugin in order to examine its tonal properties. The behavior of the digital model corresponds satisfactorily to real amplifier circuits. Important sound effects of analogue tube amplifiers can also be attested to the digital model.
Diode modelThe first step was to develop a triode model, based on the characteristic curves of real tubes. In theory, the characteristic curve of a vacuum tube is described by Langmuir-Child’s law. However, it was quickly realised that compared to real tubes, this law is not accurate enough. So a new model has been developed. This model describes a triode as a mathematical function. With the model, it is possible to compute the plate voltage (Upc) as a function of the grid voltage (Ugc), depending on the working resistor (Ra) and the supply voltage (Ub).
The following graph shows this function for a 12AU7 triode with Ra = 10k and Ub = 250V: Circuit modelingBased on this model, a plate follower stage was implemented. Cathode biasingIn this circuit, cathode biasing is used to adjust the bias point of the tube. This is realised by a resistor (Rc) and a capacitor (Cc), placed between the cathode and ground. The effect of cathode biasing can then be modeled by a simple first order RC low pass filter, with Ic*Rc being the input of the filter, and the cathode voltage (Uc) being the output.
If the input signal jumps for example from 0 V to 5 V, the cathode voltage follows quite similar to the step response of a RC-low pass filter: Signal limitingThere are two reasons for signal clipping in this circuit. The first one is caused by the tube itself. If there is a high peak at the negative half-wave of the input signal, the tube can’t amplify the signal anymore since the flow of current is completely cut-off. Thus, the positive half-wave of the output is clipped. This effect can be intensified by a more negative bias point.
Here the bias point of an 12AU7 is at around -12 V: The second reason for clipping is caused by grid current. High peaks of the positive half-wave of the input signal make the grid voltage positive compared to the cathode voltage. In this case electrons are attracted by the grid. The grid current causes a voltage drop at the internal resistance of the previous stage, which limits the input signal. The following figure shows the effect. The grid voltage is obtained by shifting down the input signal (Uin) by the cathode voltage (Uc). In the upper picture the maximum grid voltage (Ugc) is ~ 0 V compared to the cathode. Hence, there is no grid current. In the lower picture the input signal has an amplitude of 10 V. At the positive peaks of the input signal the grid voltage rises above 0 V (compared to the cathode). The grid current begins to flow and clips the grid voltage.
The Analog Rack Chorus plugin is a very simple but powerful chorus plugin inspired by the most famous Chorus pedals and rack effect units.

Decentralized by Bass Gnomes is a Virtual Effect Audio Plugin for Windows. It functions as a VST Plugin.
Decentralized is the result of an experiment done with some strange mid/side routing mixed with signal comparison and cancellation, and also an homage to Bitcoin and the decentralization movement. The result was surprisingly pleasant when use properly on either independent channels or even an entire mix. The stereo image is widened, but no delay is being used. It’s more than just boosting the side mix and I can’t exactly explain what it’s doing, and it can also create the effect of having no central point of sound when used properly. This plugin is 64-bit(x64).
Gala is a successor to our virtual analog instruments line which actually combines all of them under a single roof in 2 versions:
Gala XL – 28 instruments (royal pack member)
Gala free – 15 instruments (Free)
Both versions share the same basic features (which will be listed below) while the differences between them are:
Gala XL has keyboard split feature which allows splitting the hardware keyboard into 2 zones and routing each of the 4 oscillators to any zone
Gala XL has a new feature called “note slider” which allows creating note sliding sequence effect
Gala is based on an improved physical modeling code of a virtual analog oscillators that work in an open mixer format and mixes up 4 independent top crafted wave-forms with an incredible dynamic range and generates 28 instruments ensemble emulation, each with it’s own size and color which can mix any 4 instruments together and create rich multi combinations, articulations and textures.
Gala XL instruments:
3 pop strings.
5 oriental strings.
4 cinematic-pop brasses.
4 oriental organs.
Gala Free instruments:
3 pop strings.
4 cinematic-pop brasses.
Gala (both versions) has full synthesis section, 2 different MIDI velocity options, a user friendly global hipass-lopass filter, a full section of built in effects (saturation, chorus, phaser, tremolo, reverb and delay), built-in draw-bars system per oscillator, an advanced mono mode, full MIDI map, stereo and gleam effect and a resizable and customizable GUI.

Freeware VST Plugin Brandulator is a complex sound processor that allows you to get quite interesting combined effects – comb filters, trance gate, vocoder, wah-wah, various types of modulation (chorus, flanger, phaser, ring, etc.). The work of this plugin is based on splitting the original signal into uniform intervals, in accordance with the tempo of the musical composition, to each of which a certain type of processing can be applied.
To expand the functionality of the plug-in, there are three individual channels of sound processing, with adjustable volume and panning, which allows you to create a realistic stereo sound picture. Each channel has 16 pairs of mode / key controls called steps. It is possible to set the parameters of the steps both individually and in a group method. Also, this can be done both in manual and in automatic mode, in accordance with the required harmonic law, of which there are about three hundred different scales in the plugin’s database.
