Pulteq like EQPTEQ-X
The PTEQ-X is one of the best clones of the legendary Pultec EQP-1A equaliser you can get, including the option to simultaneously cut and boost a selected low frequency for power and clarity. PTEq-X is meant to be used as a studio equalizer for tracking, mixing and mastering inside hosts capable of VST or AU Plug-Ins support. It also sounds great All this with a premium quality for FREE !
Sidechain compressorSimpleSide
SimpleSide is a freeware volume automation plug-in designed to simulate the distinct pumping effect of sidechain compression. Although that is SimpleSide’s forte, the plugin is capable of some complex volume automation, too. The volume curve can be easily adjusted to any shape using the built-in wave editor. The only other control on the user interface is the timing knob, which goes from 1/32 all the way to 16/1.
Compared to other free plug-ins with similar functionality, SimpleSide feels very responsive, is bug-free, and uses very little CPU. We are very fond of this plug-in as a simple freeware alternative to paid products like KickStart and VolumeShaper.
Low Harmonic ProcessorBx_Subfilter
Developed by Brainworx and released by Plugin Alliance, bx_subfilter is a neat freeware utility for putting the low end of your mix under control and boosting the bass without masking other instruments.
The plugin uses a resonant low-pass filter to boost the specified bass frequency while cleaning up the extreme low end to improve clarity. It is a 2-in-1 tool for handling the sub-bass content, and it is equally effective and easy to use.
Stereo Monitoring Tool2BusControl
2BusControl is a freeware mixing and mastering tool designed for monitoring the master bus. The plugin features stereo balance and correlation meters, along with a stereo flip switch, channel solo buttons, a stereo-to-mono control, and a stereo difference monitoring switch.
Pitch Correction / Vocal ProcessorGraillon 2 Free
Graillon 2 Free is an excellent free auto-tune alternative in VST and AU plugin formats for PC and Mac. Essentially a lightweight freeware version of the Graillon 2 ($29 value) plugin by Auburn Sounds, Graillon 2 Free is still a very capable plugin and one that we’d highly recommend as your next go-to pitch correction tool. Despite lacking some of the features found in the paid product, the most important functions, pitch shifter and pitch correction, are included and fully functional.
Virtual Analog SynthesizerTyrell N6
Based on a design similar to Roland’s classic Juno 60, the U-He TyrellN6 is a powerful overall plugin that will give you all varieties of nice and lush analog synth sounds.
Bitcrusher / Distortion Krush Bit Crusher
With its bit crushing and downsampling algorithms, Krush combines the crispy taste of the digital realm with the warmth of its drive stage and analog modeled resonant filters. A modulation section allows you to quickly add extra life to the sound by modulating any parameter.
The sound palette produced by Krush ranges from the dirtiest digital effects to crunchy modulated colours, with all the classic and weirdest bit-crushing effects in between.
Chorus effectMultiply Chorus
Acon Digital Multiply is a free and versatile chorus effect with a unique twist. Each simulated voice is processed with a phase randomizing filter so that unpleasant comb filter effects are avoided. The effect can be used to simulate the effect of several performers playing the same tones simultaneously, to widen the spatial image or to create special effects for sound design.
Vintage ReverbOril River
This is probably the best free vst reverb plugin released in 2017, the user interface will make any expensive reverb plugin shy, not only it looks good but it tastes good, I mean sound good. Features like EQ, adjustable Room size, diffusion, modulation, width and many other features make this free reverb vst plugin worth in your free vst plugins library.

Even tho this one is an oldie, CamelCrusher still is one of the best free ‘colouring’ multi-effect plugin. It offers two characteristically different distortion sounds which can be blended together to create a wide variety of tones and textures. Great for guitars, drums and plenty more!
ClipperClipShifter
ClipShifter is a wave-shaping audio plugin that functions like a clipping-style limiter. It provides enough user controls to be useful in all mixing stages: from distorting basses and drums, to maximizing mix buses and warming-up overall mixes. The sonic characteristics of the clipping distortion can be altered from hard, brickwall-style clipping, to softer saturation with compression.
Frequency Shifter / EchoFreq Echo
Bode-Style Frequency Shifter + Analog Echo Emulation = Skull Melting Chaos.

Haas EffectQuick Haas
The ‘Haas Effect’, also known as the precedence effect, is a psychoacoustic effect where listeners can perceive the special position of an audio signal depending on very small delays between the left and right channels of the audio signal.
