The legendary plugin maker GSi is back with a new release: VariSpeed, a free plugin simulation of the WEM Copicat IC400 “Belt Drive” tape delay unit from the late seventies. WEM Copicat IC-400 Belt Drive VariSpeed was the first tape echo machine made by WEM with a DC capstan motor capable of changing speed, thus varying the delay time.

“My audio sample sounds dry” – I’ll add a reverb effect to make it wet (sound roomy) a little!

That was a joke, I can bet you have come across several effects in your software applications (DAW) such as reverb, delay, compression, distortion, and other various effects.

But! Vst audio plugins. Why do we use audio effects in the first place?

To answer that question, I’ll ask you a simple question. How would your meal taste without any ingredients?

Tasteless right! Yh, sure, it’s still eatable but it lacks flavor. Let’s transition back to the old question, why do we use audio effects?

Audio effects are software devices (ingredients) that manipulates an audio signal to a specific taste, it can make a dry audio signal sound wet, it can help in controlling the gains of an uncompressed sound (proper leveling of peaks), it can make a dull audio sample sound lively, and it can also be misused (think of adding too many/too little salt to your meal).

Since we know the importance of using audio effects, I would be recommending some of the best free VST effects plugins.

It doesn’t make any sense to randomly list the effects, so I decided to categorize each and every effect, all compressor vst effect plugin would be under the Compressor Vst category, reverb vst effects plugin would be under Reverb Vst category, you get the idea.

Compressor Free VST/AU/AAX Plugin

Compression is an effect or an audio processing tool that is used to control the overall Dynamics of an audio signal or an audio portion.

Some of the best free compressor plugins are…

1.) Audiofb – SeteChave Compressor

SeteChave is the first compressor on our list and is designed with characteristics close to the “pumping” effect. It can be used for parallel compressing and it is really intuitive with minimal knobs, so, you will quickly get a hold of this one.

Features:

• Input – Input signal gain control from -12db to + 12db
• Att – Attack spanning from 1.2ms to 500ms
• Rel – Release ranging from 20ms to 5s
• Threshold – with decibel range from 0db to -36db
• Ratio – Compression ratio, ranging from 1: 1 to 200: 1
• Knee – Curve gives compression, which varies between values 1 and 5 Output – Output signal gain control from -12db to + 12db.

Specification Requirements:

• Windows: Minimum of Win 8.1
• Mac OSX: Minimum of 10.10

2.) TDR Nova

Nova is a parallel equalizer and a multiband compressor that can tackle and fix a wide range of applications when processing. It can feel a little bit daunting when using TDR due to its various knobs, but you should easily get familiar after experimenting with its features and besides, it is free 😉

TDR NOVA is useful and works with all kinds of audio material, be it a drum bus asking for more crispiness, or a sibilance issue with your sounds, Nova got your back!

A simple UI design, drag and drop display with a classic “Knob” interface given quick and smooth access to the various parameters driving NOVA’s powerful processing capabilities.

The most interesting thing about this tool is that it has a rare feature you would find in Nova is that it allow users to copy and paste presets, and a lot of more great feature.

Features:

• Parametric equalization
• Dynamic equalization
• Frequency selective compression
• Multi-band compression
• Wideband compression.

• Win 64bits formats: VST2/VST3/AAX
• Mac OSx 64bits formats: VST2/VST3/AU/AAX

3.) T-Chain

I can’t even believe this is free (well, partially!)

T-Chain as it names sounds, it is a chain of different plugins or a channel strip plugin that is designed for modularity, users can arrange different sound modules within the signal path, you get the idea!.

For example, you might decide to use it as a single Eq or a compressor module and if you so wish, you can arrange different sound modules such as a free EQ, Compressor, Gate, and Splitter (for splitting the signal into two distinct paths), one of the most exciting features about this free plugin, is that the module can be rearranged, added, and deleted by drag-and-drop, this way, your life can be easier rearranging your signal chain.

I should mention some modules aren’t free but getting a free Eq, compressor, gate, and splitter is more than enough for so many use cases.

Features:

• Free and Paid modules, with the ability to demo any module at any time
• Customizable spectrum analyzer and waveform display
• Full-featured preset management system with searchable filter and text-based importing/exporting
• Multiple plugin interface size (compact, small, medium, and large)
• A/B Comparison feature for the entire plugin, and for individual modules

Specification Requirement:

• Available on Mac and PC; in VST, VST3, AU, and AAX formats; and 32- and 64-bit architecture

Kotelnikov is a wideband dynamics compressor that is designed with high fidelity dynamic range control with deep musical flexibility. Their Nova plugin is a combo of Eq and Compressor while Kotelnikov is built solely for dynamic processing and has an on par features such as a proven control scheme, individual release control for peak and RMS content, an intuitive user interface, and powerful, state of the art, high-precision algorithms.

This plugin is suited when used as bus compression and or a master channel, if you try throwing many instances of Kotelnikov on your mixer inserts, you’ll eat your CPU up!

6.) Beatskillz – Max1

I might be biased in this review but personally, this is one of the best auto-compressor plugins out there. Max 1 will automatically analyze the ratio depending on the audio source and compress accordingly.

If you feel itchy about using an auto compressor tool, you are as well covered, Max1 comes with the default compressor knobs (Threshold, Attack, Gain, and the likes). In addition to this, it also comes bundled with a soft clip switch so you can clip anything that goes past 0dB, this way, you can save extra effort using a Limiter.

Features:

• Auto-Compressor with “intelligent” and variable release time and ratio settings.
• Control your peaks very easily or increase the energy and levels of your track or mix effortlessly.
• The Plugin has accurate metering for both L/R input and output channels as well as Gain Gain Reduction Metering.
• Great Presets to get you started on all types of material and also save your own presets.
• When compressing a lot, just use the “Attack” knob to dial back the punch easily. Use the soft limit to make your track loud effortlessly and transparently.
• Never Lose “Bass” when maximizing your mix or sounds, retain the character of your sounds with this transparent dynamics processor.
• Easy Effortless Compression and Energy Maximization.
