Flower Child Filter

Flower Child Filter free filter by Soundemote

Flower Child Filter is a free filter VST, Audio Unit plugin developed by Soundemote. Compatible OS(s): Windows 64b, macOS.

Flower Child Filter is the first in an upcoming series of boutique analog-style filters (See FMD). Flower Child is aptly named for its goal to have a clean and resonant sound. There is also a switch for an aggressive growling version that is sure to cater to your more destructive side:

  • Oscilloscope in center of interface to see realtime how the filter is affecting your signal.
  • Self-oscillating resonance.
  • Warm tube-like overdrive by setting resonance to 0 in clean mode.
  • Clean/Aggressive mode where aggressive mode responds well to loud inputs, creating pleasing warmth, overdrive, and distortion.
  • 2 Envelope followers, one for filter, the other for amplitude.

Floorfish

Floorfish free gate by digitalfishphones

Floorfish is a free gate VST, Audio Unit plugin developed by digitalfishphones. Compatible OS(s): Windows 64b, macOS.

Floorfish is a simple expander / gate device, easy to set up and offers a broad variety of processing, ranging from slight expansion, background noise attenuation to extreme gating effects.

What’s different from similar units is the ability to scan the source and adjust the transition curve accordingly.

FLOFIdeluxe

FLOFIdeluxe free glitch by BetabugsAudio

FLOFIdeluxe is a free glitch VST plugin developed by BetabugsAudio. Compatible OS(s): Windows.

FloFi combines a filter with an octave pitch shift algorithm. The filtered signal runs through the pitch shift, at which time it may be further altered. This signal is then added back to the original, for effects ranging from a subtle livening of dead sources, to trashy thrash.

FloFi has 5 controls:

  • FREQ – The source frequency that will be shifted up by an octave.
  • WIDTH – The width of the frequency band being shifted.
  • BOOST – The amount of level boost applied to the pitched signal. A limiter works to prevent unmusical digital distortion.
  • DETUNE – The signal being shifted can be detuned by approximately +/- 2.5 semitones.
  • MIX – The amount of the pitch-shifted and altered signal to be mixed back into the original.

Flipper

Flipper free other-utility by reFuse Software

Flipper is a free audio and studio utility VST plugin developed by reFuse Software. Compatible OS(s): Windows 64b, macOS.

Flipper flips signal polarity (misnomered often as “phase”). That’s it. Why should you care, when so many plug-ins already include a polarity switch in them? Well, because so many DAWs do not include a polarity switch right on their mixers. This means that, instead of being able to try different polarities with ONE click of the mouse, you must open some random plug-in, hunt for the polarity switch, and then hit it.

The idea of the Flipper is to effectively add a polarity switch to any DAW mixer. If the Flipper is on, it’s flipping polarity. If it’s in Bypass, it’s not.

Previously available only as a Pluggo plug-in, the free Flipper plug-in has been reissued in 2019 in native AAX, Audio Unit, and VST formats.

Flextron DC14

Flextron DC14 free amp-simulator by AXP

Flextron DC14 is a free amp simulator VST plugin developed by AXP. Compatible OS(s): Windows.

Flextron is a virtual-analog guitar amp based on a concept of the hybrid guitar distortion pedal I’ve built for myself a while ago. The prototype pedal in its turn was based on two commercial tube emulation technologies – Flexwave by Crate and Cooltron by VOX. This combination was discovered by accident when I was repairing my bandmate’s VOX Bulldog distortion pedal. I didn’t like the Bulldog that much, however I got interested in its low-voltage tube design so I assembled a copy on a test bench. On its own it has provided very little overdrive, just as expected, but when combined with the Crate Flexwave preamp (my favorite solid-state distortion) it has completed its already great tone, giving it more fullness and presence. I’ve used this arrangement for rehearsals and some gigs and got complemented for the tone.

Flextron goes a step further and accurately models a range of Crate solid-state amps powered by the Flexwave circuit. Every stage of the preamp signal path is carefully analyzed and modeled with the same attention to details as my previous SoftDrive GV and SoftAmp FM25 plugins.

The Flexwave amp design has evolved over the years. I counted 6 different variations. After careful analysis, I’ve narrowed down the scope to 3 models. The one I’ve played with was made in the late 90’s and I think it’s ahead of the pack. However in 2000’s they have changed the gain channel structure significantly and after some consideration I’ve decided to model all three.

The Cooltron circuit in its turn stayed the same across their pedal range. I’ve tried a couple of different approaches to modeling it before settling on the final one. Since I’ve had a real physical implementation at my disposal I was able to successfully verify the accuracy of the digital model.

Interestingly, both Flexwave and Cooltron follow exactly the same idea – they essentially are an asymmetric clipping stage biased by the low-passed feedback signal. Having made my own SoftAmp 3OD model I can say that this is exactly how a real guitar amp triode stage works. The main difference is that Cooltron uses a 12AU7 tube running on 6V anode voltage for the authentic tube waveshaping, while Flexwave relies on an asymmetrically configured “rubber diode” pair to achieve the same effect.

In addition to the fully featured 3-channel preamp and a tube saturation stage, Flextron offers a dual-mode stereo reverb (algorithmic and convolution-based), a speaker simulator with two cabinet models and an ambience control (intended mainly for practising in headphones), a switchable order oversampling and a set of visualization instruments, such as an EQ curve plot and stage bias meters.

Just as with my previous plugins, every single control is remapped to produce linear response on a dB scale.

Additional details can be found in the bundled manual.
