Free EQ & Filter Plugins

QB3

QB3 is a free equalizer VST plugin developed by de la Mancha. Compatible OS(s): Windows.

QB3 is a vintage-style, 3-band EQ plug-in, with its own unique colouring and a few tricks up its sleeve. For each band you can adjust the centre frequency and gain. For the low and high shelving bands you can adjust the steepness of the slope, whilst for the mid peaking band you can adjust the bandwidth. This allows a range of sounds from steep, sharp cuts to smooth and gentle boosts.

But the “Queen Bee” is not a super clean and transparent plug-in. QB-3 features a pleasing combination of harmonics, saturation and low level noise to bring a subtle mojo to your sound. You also have the option to switch on a 40Hz cut to boost your low frequency headroom and a limiter to curb any peaks.

Features:

Vintage-style, 3-band EQ.

Subtle colouring from a home-made blend of harmonics, saturation and low level noise.

Full Stereo processing.

Centre frequency adjustable for each band.

Gain adjusts positively and negatively for each band.

Low and High bands have adjustable slope, including negative ‘resonant’ like curve.

Mid band has adjustable bandwidth for narrow to wide curves.

Master gain control.

Optional 40Hz cut for low frequency optimisation.

Optional limiting on final output.

Non-linear knobs for precise control at small values, with double-click reset to default value.

33 Presets covering many different configurations.

Additional selectable frequencies for the PEQ1A model, compared to the original design.

Refined filters frequency precision for the MQ5 and HL3C models, compared to the original design.

Switchable equalizers and tube stage modeling for better CPU usage management.

Switchable linear phase oversampling for aliasing reduction.

Global input / output level controls.

posihfopit

posihfopit is a free equalizer VST plugin developed by Christian Budde. Compatible OS(s): Windows.

posihfopit is a soft clip EQ effect plug-in.

With posihfopit you can very easily equalize your audio material, but furthermore the plugin will add a new color to the sound. Due to its unique transistor based algorithm, a small amount of soft distortion is applied according to the filter band used. This way your material gets kind of “creamier”.

Features:

8 band EQ (with additional soft clip).

Peak / LPF / HPF / LowShelf / HighShelf / Allpass / Notch / Bandpass / Moog.

Auto filter calculation (5 different algorithms).

Skinnable/intuitive GUI (several skins included).

Integrated overview over every instance.

‘default’ can be customized.

Pipeline Pressure Control

Pipeline Pressure Control is a free filter plugin for Reason developed by Turn2on. Compatible OS(s): .

Take full control of the water network right from the Reason rack. Adjust the pressure in the pipes, the flow rate, and even eavesdrop on what is happening on the other side of the pipe or inside it.

Product details

By passing a signal through a pipe, you simulate analog filtering. When a signal passes through a pipe, harmonics saturate according to the selected pipe type.

With this effect is available:
– 22 types of pipes
– pressure monitoring by means of a valve
– visual control
– correction of the signal level at the pipeline inlet and outlet.

The device is a means of monitoring the signal in the underground communication environment. This is one of the most recent techniques for check mixing control in our days.

pfilter

pfilter is a free filter and gate VST plugin developed by de la Mancha. Compatible OS(s): Windows.

pfilter creates a steppy, gated effect, but using filter cut-off instead of volume to give a wider range of possibilities. It uses a variable state filter, triggered between 2 adjustable cut-off values by a tempo-sync’d probability-based step sequencer. An LFO can modulate the filter when triggered and trigger pulse length, attack and release can shape the sound

Features:

Tempo-sync step sequencer, with 2 to 32 steps over a sequence length of 2 to 32 beats.

Can be programmed or random, by setting the probability of each step from 0-100%.

Seeded randomisation for repeatable loops up to 100 beats long.

Resonant variable filter, LP, HP, BP and notch.

Filter triggered between upper and lower cut-off values, in either direction.

Tempo sync LFO, with 6 waveforms and settings from 1/16 beat to 96 beats.

Adjustable pulse length, attack and decay for shaping the modulation.

Random swing for step sequencer.

Wet/dry mix control.

MIDI CC and MIDI learn.

Pedals

Pedals is a free multi fx and overdrive and saturation and amp simulator and delay and echo and flanger and phaser and pitch shifter and reverb and eq and filter VST plugin developed by ToneBytes. Compatible OS(s): Windows.

These devices are not a copy of the real-life models, each with their own sound, but their working principles are identical.

The user can select a combination of effects and can even create extra mood by choosing floor material under the pedals: house parquet, metal garage floor or studio carpet.

There is a built-in preset manager to save the settings and access them or share them with other users. VST automation and full MIDI Learning are supported.
