Free Audio Plugins & Softwares for Windows

Sonogram SG-1

Sonogram SG-1 is a free sonogram VST plugin developed by ag-works. Compatible OS(s): Windows.

Sonogram SG-1is a real-time sonogram allowing for fast and detailed spectral analysis.

Sonogram SG-1 Features:

Six scientific color palettes, each of them can highlight different dynamic ranges, from high power kick drum beats, to little spikes coming out from the noise floor.

Snapshots-per-second control that can be changed on the fly, to increase or decrease the time resolution.

At any time you can change the zoom ratio, without loosing frequency details for the signals which have already passed by.

The zoomed screen can be scrolled while analyzing, to easily locate the frequency range of interest.

Pause the visualization with the “freeze” control.

Both in frozen or running mode, every time you click or drag within the sonogram area, frequency and amplitude rulers highlight the values corresponding to that point.

Every palette can be shifted by simply dragging the dB ruler, to better contrast the right amplitude ranges.

A mark button is provided to highlight interesting parts of the waveform for subsequent individuation.

Every parameter supports host automation.

Sonix

Sonix is a free glitch and granulizer VST plugin developed by JC Productionz. Compatible OS(s): Windows.

Sonix is a “single-stream quasi-synchronous granulator” which also features an analog filter to further manipulate the sound with a smooth low-pass, phat-pass (with some big bottom end) and high-pass formant hybrid settings.

Features:

Random grain variation.

Grain pitch control.

Auto pitch variation.

Hybrid analog filter.

Panning on both channels, only on stereo audio track.

Grain shaping envelopes.

Wet & dry signal control.

Full automation.

MIDI learn functionality on all controls.

Optional host sync for grain rate.

Granulators can be triggered in stereo mode or separately.

Both granulator channels can be operated independently.

Sonigen Modular

Sonigen Modular is a free software synthesizer developed by Sonigen. Available format(s): Stand Alone, VST for Windows.

Sonigen Modular is a modular software synthesizer which combines the freedom and flexibility of classic modular synthesis with the benefits of a modern software implementation. The user interface is quick and intuitive to use while still affording the sound designer great freedom. The audio processing algorithms are of high quality while still being CPU efficient.

Features:

Sonigen Modular is fully modular, with as many modules and patch cables as you want.

It combines polyphonic voice and static effect processing in one window. That means you can have multiple MIDI notes playing multiple voices, mix them all down to a single stereo stream and route that through a modular effect chain.

It is fast and intuitive to use, almost everything is done in the main module window. There’s no separate schematic / GUI views, no macro modules, no separate FX window. You can see what is going on just by looking at the main window.

Great sound quality. A huge amount of time has been put into developing high quality algorithms. It has very good aliasing rejection in most cases.

It is CPU efficient. This doesn’t mean corners have been cut. It means hand tuned assembly and run time optimization. The audio processing code is dynamically assembled and optimised in real time as you edit and play.

SonicPhoto

SonicPhoto is a free audio converter plugin developed by Skytopia. Compatible OS(s): Windows .

SonicPhoto is an audio program to convert from pictures, photos and drawings to sound. Each picture has its own ‘signature’, and SonicPhoto will allow you to hear what the picture sounds like.

Higher parts in the picture create higher pitches, while lower areas create deeper tones. Likewise, brighter areas make that tone louder (and darker areas, quieter).

Also included is an instrument/harmony feature so you can create stunning tonal sounds, such as sparkling synths, rippling arpeggios, howling winds, deep organs, dazzling lasers, roaring bass and metallic drones.

Features include:

Create an infinite variety of sounds ranging based on the patterns in any picture.

Instrument and harmony quantization so you can create tonal sounds.

Dozens of in-built presets, so you can immediately try sounds out and experiment.

Convincing stereo is automatically added to all sounds.

Very easy to use GUI with everything you need at a click of a button.

Well thought out system to loading and save custom projects.

Instantly adjust the quality to suit your needs (low for preview, high for final result).

Uses:

Experimental composers will appreciate the otherworldly sounds SonicPhoto can produce with ease. Sounds lasting up to an hour in length can provide a backing soundtrack to a film, or be mixed with a piece of music to enrich the atmosphere.

On the shorter end of the time scale, sounds lasting less than half a second can be rendered, with all the aforementioned options such as tonality and frequency adjustment to hone the sound to your requirements.

Video demo:

See SonicPhoto in action with this video demonstration below (also see right for MP3 only samples).

32-bit IEEE Floating Point internal signal path.

Code optimization for realtime performance.

All parameters Fully automatable in supported host applications.

Import/Export parameter settings to a spreadsheet file.

SonicBirth

SonicBirth is a free development tool VST, Audio Unit plugin developed by SonicBirth. Compatible OS(s): Windows.

SonicBirth is an “AudioUnit/VST designing application“. It allows users to build their own AudioUnit/VST plugins, either by working with existing circuits or by creating circuits completely from scratch. SonicBirth is also an AudioUnits package, as it comes bundled with a set of plugins designed for standalone use as plugins as well as pre-constructed circuits to modify or build upon for creating new plugins. Whether you’re looking for traditional eqs, compressors, and reverbs, or softsynths, distortion, and filters, etc., SonicBirth allows you freedom and creativity over your sound.

SonicBirth is based on a powerful, flexible engine. Every plugin can be used in 32 bits or 64 bits for added precision. Since all plugins share this engine, any improvement in speed will benefit all of them.

Sonic Transformer

Sonic Transformer is a free multi fx VST plugin developed by Ourafilmes. Compatible OS(s): Windows.

Sonic Transformer is an “alien-style complex multi-effect processor”. With its original 5 “alien eyes” knobs, you can control several parameters simultaneously (or a percentage of an effect parameter). The “hybrid” knob controls the dry/wet mix.

The use of this plug-in is completely enigmatic and chaotic, but allows you to get effects from reverb to powerful filters, from chorus to delays, and more… 7 presets are available but you’ll realize that by only altering one knob the sound changes a lot. This feature allows you to radically transform the sound.

Sonic Transformer includes full automation and MIDI Learn.

See the video to see how it works.
