Free Audio Plugins & Softwares for Windows

Akai EWI-USB Control

Akai EWI-USB Control is a free studio tools plugin developed by Cognitone. Compatible OS(s): Windows, macOS.

Utility software for the wind controller hardware EWI-USB from Akai Professional.

Provides controls for all the hardware’s parameters and allows for saving frequently used presets to disk. This way you can keep multiple settings for different setups.

Akai EWI-USB Control can be chained between the controller hardware and a sequencer or synthesizer software in order to filter the MIDI data stream in real-time. Four different key switches can be assigned to individual hardware sensors and trigger specific sound articulations this way.

Summary:

Control all hardware parameters.

Save and load presets.

Filter MIDI data stream in real-time.

Assign hardware sensors to key switches (articulations).

Requires Akai EWI-USB hardware.

Afterlife Free

Afterlife Free virtual instrument is a free sound bank for Kontakt, by ForceSampling.

Afterlife Free is is the free version of the Kontakt library Afterlife, featuring 1.06 GB of sample content and 100 patches hand-picked from its big brother.

The library content covers a wide scope of different genres (cinematic, ambient, dnb etc.), but its goal is not to provide bread and butter sounds for modern genres, instead the focus is to bring unusual and unexpected sounds to give extra spice to your compositions. Distorted synth brass from dystopian lands, surrealistic drones from your weirdest nightmares, ethereal pads full of enlightenment and morphed acoustics that sound both natural and otherworldly, all in the same library.

Tweak the sounds fast and easy using the simple interface that provides a filter, amp envelope, 4 band eq, arpeggiator and 4 custom fx buttons. These buttons offer easy tweaking of all patches, just with a one or two clicks.

Aethereal

Aethereal is a free software synthesizer developed by Psychic Modulation. Available format(s): VST for Windows.

Aethereal is an ambient vector synth equipped with several atmospheric sounds, tones and FX for creating evolving soundscapes and textures. The sounds, which are in the form of four wave oscillators can be mixed between using a sophisticated 4-Way TransMixer, either manually, with Auto-Modulation or in a set transition from one sound to the next.

Other modulation options include a Multi-Vector, which uses three X/Y position points to modulate various parameters, a 16-Step Mod-Sequencer, three modulation envelopes, plus assignable pitchbend and modwheel, making Aethereal a flexible and expressive ambient synthesizer with many possibilities.

Features:

Over 100 built-in sounds such as synth tones, atmospheres, vocal pads and sound FX.

Four wave oscillators with independent amp envelopes; the oscillators are divided into two sections that can be routed to separate audio output channels.

4-Way TransMixer for making set transitions from one sound to another; can also be used for manual or automatic mixing.

Multi-Vector for modulating various parameters in an X/Y path.

Auto-Modulation section for automatic control of the Multi-Vector as well as the TransMixer (modulation equivalent of 8 LFOs).

16-Step Modulation Sequencer – For sequenced modulation of pitch and filters.

Two filter sections, each with independent envelopes, inverters, gain compensation & multiple stages (1-4).

Three modulation envelopes.

Dual Stereo Delay section.

Assignable pitchbend and modwheel.

64 presets.

A fully-functioning freeware version is available, with the limitations of only two voices polyphony and one audio output.

Aerophone

Aerophone is a free software synthesizer developed by xoxos. Available format(s): VST for Windows.

Aerophone models lip valve instruments with cylindrical bores such as trumpets and trombones. The lip valve is modeled with an oversampled 3rd order mass-spring to emulate expressive styles of brass performance.

The elementary circuit is an effective platform for producing a range of emulative timbres, however to apply humanised performance values requires significant effort and knowledge on the part of the user.

Features:

1 Drawable Oscillator. (128 samples).

1 Drawable LFO, that can be used as an envelope.

ADSR with adjustable slopes.

Two types of Phase Distortion/Modulation.

A Low-Pass Filter.

Can add Harmonics to the Drawable waveform.

Waveform copy and paste.

Advanced Clipper

Advanced Clipper is a free limiter and clipper VST plugin developed by Christian Budde. Compatible OS(s): Windows.

Advanced Clipper is basically a hard-clipping plugin with two stages. Additional oversampling reduces alias noise. The oversampling algorithm is based on butterworth filters (as can be found in rubberfilter) and thus will affect the group delay (you can notice a delay of some samples in extreme cases).

Features:

Two stages of minimum phase, butterworth oversampler.

Hard clip at higher sample rates.

Oversampling of up to 16x (in both stages).

Filter order up to 64 (using the max. order will introduce noticeable group delay).

Tunable transition frequency (in parameter view).

adsrFilter

adsrFilter is a free filter VST plugin developed by SaschArt. Compatible OS(s): Windows.

adsrFilter is a filter with ADSR envelope which can modulate filter frequency, bandwidth and filter mix! Extremely low resources taken.

One filter with lowpass, highpass and bandpass.

Bandwidth and filter mix.

ADSR envelope with unique up/down mode.

Volume compensation for ADSR with crescendo side to right, left or both.

Visualization of modulated parameter value.

Presets for uplifting, glissando and bandwidth by octaves.

Midi reset button.

Requirements:
VST host and Windows 32 or 64-bits.
