You may think of Toolfarm as a place for just visual effects plug-ins and video tools, but we also know a bit about audio plug-ins. Did you know that many NLEs support audio plug-ins? This is a guide that explains the difference between Native and DSP-based plug-ins. Find out which format works with your system, whether you’re using ProTools, Cubase, Media Composer, Premiere Pro, DaVinci Resolve, Vegas or Final Cut Pro X.

Updated: March 14, 2017, with new information on DaVinci Resolve and other tools.


When I was at the University, I received a BA in Communication, with a major in Film & Video and a minor in Audio Production. Those audio production classes were a lot of fun, especially the MIDI class I took where we learned Cakewalk. 

Although I don't do a lot of audio production these days, I often have a need in my video work to fix audio. I've had to time stretch audio to fit the length of the video. How is that done with out shifting the pitch? I'm sure you've had to remove buzz or echo from your audio. Once I had to remove a squaking bird which was in the background of some training I was editing. I ended up taking the video into Adobe Audition to remove the squaking and buzz, but, iIf you don't want to use a full blown audio production tool, some of these plug-ins will work in your NLE. 

The vast array of audio plug-ins available is mindblowing, and they come with all sorts of formats that you may not be familiar with if you mainly work with video. Toolfarm caries a number of audio tools and plug-ins and our selection is growing every day. Many of the plug-ins support multiple formats, so it gets a bit confusing. Native, AAX, AU, RTAS, TDM, and VST.... what do all of these acronyms mean?  Let's break it down.

Native Format vs. DSP-based Plug-ins

First, lets split these into two categories: Native Format vs. DSP-based Plug-ins

Native plug-ins work with the computer's CPU and do not require any special dedicated hardware, such as DSP chips. Native plug-ins are mainly programmed with C++, making it usable over multiple platforms. There are a lot of native plug-ins on the market and available for free. 

DSP-based plug-ins rely on DSP chips, or Digital Signal Processor chips, are third party cards, which can get pretty expensive. Plug-ins for DSP-based systems are also more expensive, however, users love the quality.

VSTVST - Native

VST (Virtual Studio Technology) is a native framework that was developed by Steinberg. The plug-ins come in three types: VST Instruments, VST effects and VST MIDI effects.  VST 3.5, which came out in 2011, is the current version. The majority of plug-ins are Windows only due to competing Audio Unit, which is built into the Mac OS.
