Free Audio Effects Plugins Masterlist

A comprehensive list of audio processing plugins available for free download. This is a dynamic list and will be updated as new free audio plugins become available. If you would like to see any added to this list, feel free to contact me.

This list was conceived so that people starting up in all forms of professional audio or trying to do it with limited resources, can have access to as wide a set of tools as possible.

No virtual instruments, that’s a whole different category. We just cover processing plugins (including meters and whatnot), for mixing or mastering and sound design.

As always, if you’re looking for Audio Mastering services at a reasonable price with quick turnarounds, feel free to message me. For more about why you should master your songs, check out my post – ‘why master?’.

These are some old plugins that SSL had released for free on their website in the mid 2000s. They are no longer available on their main official site, but they are still mentioned on their site hosted in japan and the installation files still remain on their servers (to which we are linking to).

These installers will most likely not work on modern systems (Windows 10, MacOS)

[32-bit VST only]

“In each of my effects there is a special technical design, workflow or concept combination I haven’t found in existing tools. Many developers these days just stick to old concepts, but you will never see a straight copy of existing gear from me. I always add some innovation, or find a way to evolve and take it to a new level.”
