Luckily, there is no need to stress out every time you get to the mixer and start working on getting the “perfect vocals.” All you need to do is to know which free vocal mastering VST plugins. Voxengo’s SPAN is something of a classic in the audio world, providing spectrum analysis capabilities equal to that of the best plug-ins.

But can you make 'professional' sounding mixes with free plugins? The answer is yes!

What makes a good free plugin:

  • It does not sound 'free'
  • It is competing with expensive plugins on at least a few features
  • CPU usage not too high
    • Free plugins might not be as optimized as selling plugins
  • VST 3 format is a plus but not a must

Like in Vintageverb and Room the modes have names

OrilRiver Reverb

This is one of the better sounding free reverbs. No low quality ringing and it has a nice diffusion. It does not quite have the pro feel of Supermasssive but still a good free tool for a good reverb.
