Get the 200 best free VST plugins ever made. From synth VSTs and drum VSTs to VST effects, this huge list has only the best of the best plugins. 6 of the best VST/AU phase alignment plugins to whip your mixes into shape By Future Music ( Future Music ) 15 May 2019 Correcting phase issues might not be the most exciting task in music production, but at least it can be one of the easiest thanks to plugins like these.

You may face several scenarios while mixing and mastering which may include the use of an equalizer, having a transparent display to analyze what you are adding or subtracting with the EQ, multiple EQ bands, and proper CPU usage is what to look for in an EQ.

MMultiAnalyzer is a unique multi-track spectrum, loudness and stereo analyzer and sonogram, which reveals problems and frequency collisions quickly, easily, and with astonishing accuracy. Just put an instance on each track in which you are interested and they automatically find each other and exchange their respective analyses.

But with that said every piece of software and hardware alike creates and outputs a slightly different sound meaning they all have unique timbres and uses. Alongside that, there are some rather expensive plugins we may see online, which aren’t out of our reaches but we don’t know what we need until we need it right? Well, this is why its best to try some free EQ’s first to see what it is you like within an EQ and what it maybe you are looking for.

We become ever so comfortable with our stock plugins, they do the simple tasks for us (sometimes), they don’t run our computer into the ground, and they for sure are pretty basic. Well, this is the issue most people come to, they want a better EQ, or they want a change of visuals.

Features & When To Use:

Colour EQ is a 64-bit EQ plugin that offers 5 ”super parametric” bands to manipulate the frequency range. This is exceedingly handy when wanting to use more than one band in one instance; the intuitive gain knobs on the five bands allow for perfect mixing of these bands when mixing and mastering.

Using the two different types of curves, Colour EQ offers a warm sound that you just wouldn’t get from your stock EQ.

Having a bright visual display helps you to craft and mould your bands to preference.

A great way to use this plugin is when you are not getting enough warmth in your low, mid/mids, Colour EQ will add a great sense of warmth throughout the selected bands. Another cool way to use this plugin is to use two different setups with two different curve types; you can use modified versions of the EQ for selected times in your mixdowns to add the feeling of a change in energy in a breakdown or drop.

Colour EQ is a great tool to have in your arsenal for mixing and mastering, plus you may find many uses in your day-to-day production.
