Free Audio Plugins VST, AU, RTAS

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.

Punish

Punish is a free multi fx VST, VST3, Audio Unit, AAX plugin developed by Heavyocity. Compatible OS(s): Windows 64b, macOS.

From subtle warmth to extreme drive and compression, PUNISH injects character and edge into any mix or instrument track. It’s the same PUNISH effect that you know and love, as featured in Heavyocity’s award-winning line of virtual instruments, now in VST/AU/AAX plugin format. Modeled after Heavyocity’s custom analog signal chains, PUNISH gives you control over Compression, Saturation, Transients, EQ, and Limiting. Chain the modules together to get that signature PUNISH sound, or isolate them to experience each dynamic effect on its own.

And at the heart of it all is the global PUNISH Knob. Simply set your ranges, and use the one knob to dial in the devastation.

Compression / Saturation

With three distinct compression models, the PUNISH Compressor offers a wide dynamic range, topped off with that classic analog warmth. The plugin features a smooth Class A-style Buss Compressor (Console), an aggressive, fat sound with a classic “knee” (Modern), and a warm vintage limiting amplifier-style (Classic).

The PUNISH Saturation module also features three different models, all with their own unique brand of warmth, drive, and character. With a classic broadcast mic-pre (Vintage), a chunky harmonic saturation (Modern), and a fat tube saturation (Tube), the PUNISH Saturation module can add a bit of grit to a track, or drive the whole thing into overload.

Transients / EQ / Limiting

Providing control over the attack, sustain, and output gain, PUNISH‘s Transient shaping module brings stronger transients back into the signal after saturating the sound. The module also features Hold control to determine length of the attack.

The EQ module is basic but powerful, offering lift of the high and low frequencies. Set the EQ to Pre or Post to affect highs and lows before the Comp, Sat, and Transient…or after.

To prevent clipping, PUNISH also features a Limiter at the end of the chain. Soft clip amount and release time controls are key, when that Saturation starts to get things truly hairy.

Pulse Modulator

Pulse Modulator is a free modulation and distortion VST, Audio Unit plugin developed by Audio Damage. Compatible OS(s): Windows 64b, macOS.

Pulse Modulator is a tremolo/distortion pedal, loosely based on the extremely rare Electro-Harmonix guitar pedal of the same name. Three separate LFOs drive a VCA, resulting in strange and unique tremolo shapes. Pulse Modulator also has a modeled distortion stage, for extra oomph.

Features:

Three independent LFOs, syncable to host tempo, driving three VCAs.

Continuously variable LFO shape.

“Boost” vintage distortion stage.

Standard Audio Damage MIDI Learn mode for VSTs (handled by host in AU).

Pulse Width Modifier

Pulse Width Modifier is a free exciter and enhancer VST plugin developed by Anarchy Sound Software. Compatible OS(s): Windows.

Pulse Width Modifier uses a procedurally controlled variable length delay line to compress the pulsewidth of the input signal’s fundamental frequency. This acts as a harmonic exciter and an interesting distorter of unrelated frequencies.

PTEq-X

PTEq-X is a free overdrive and saturation and eq VST, VST3, Audio Unit plugin developed by Ignite Amps. Compatible OS(s): Windows 64b, macOS.

PTEq-X is a digital emulation of 3 famous vintage passive program equalizers.

It has been developed to have all the characteristics of the original hardware, plus some circuit improvements and additional features to increase its versatility.

PSP PianoVerb

PSP PianoVerb is a free reverb VST, Audio Unit, RTAS, AAX plugin developed by PSPaudioware. Compatible OS(s): Windows 64b, macOS.

PSP PianoVerb reproduces a special kind of reverberation originally provided by piano strings. It generates reverberation using twelve string operators with adjustable damping and decay time. Each of them is tuned to a particular note starting from A(55Hz) to a G#(103.8Hz).

The PSP PianoVerb string system can be transposed in the range of +-24 semitones, tuned within a range of +-100 cents and be detuned as well. Transposing to lower octaves produces a bigger and less resonant sound similar to traditional reverbs, while in turn transposing to higher octaves produces a very bright harp-like effect.
