Audio plugins are small pieces of software used inside a type of software environment called digital audio workstations (DAWs); their role is to create, edit, or otherwise process audio. In other words, these plugins extend the functions of the DAW by offering virtual instruments, effects, and utilities. Whether your line of work is music production, track mixing, or sound design, plugins will become your inseparable tool.

Types of Audio Plugins

Audio plugins come in several forms, each with its function in the process of music creation. Some of them involve virtual instruments, such as synthesizers, samplers, and drum machines, for the creation of sounds, while others play the role of effects, including reverb, delay, compression, and equalization, among many more. The Utility Plugins will provide spectrum analyzers, tuners, and meters, and it will be useful for workflow and precision in audio editing.

Common Plugin Formats: AU vs VST3 vs VST2 vs AAX

Different plugin formats have different strengths and compatibilities. Here’s a list of the most common ones:

AU (Audio Units)

AU is Apple’s proprietary plugin format for macOS, primarily used in DAWs like Logic Pro and GarageBand. It’s tightly integrated with the Apple ecosystem, making it the default format for Mac-based producers.

VST2 (Virtual Studio Technology 2)

VST2 by Steinberg – probably the most popular format of audio plugins on both macOS and Windows. Although its development has been discontinued in favor of VST3, this is still supported in many DAWs.

VST3 (Virtual Studio Technology 3)

VST3 is an enhancement over VST2, providing greater CPU efficiency, dynamic I/O management, and advanced functionality such as surround sound. Thus, VST3 is the much-preferred choice among plugin developers because it is more efficient and flexible in performance.

AAX (Avid Audio eXtension)

AAX is the format unique to Pro Tools, from Avid. It’s optimized for high-end professional use in the audio industry, including working with Pro Tools systems.

Key Differences

  • Compatibility: AU runs exclusively on macOS, while the others – VST and AAX – can run on both macOS and Windows.
  • Performance: In terms of performance, VST3 and AAX are more CPU efficient and feature-rich compared to AUv2 and VST2.
  • Platform Focus: Evidently, AAX is for Pro Tools, AU fits best in Apple’s ecosystem, and VST formats offer cross-platform flexibility.

Stock vs Paid Plugins

Stock Audio Plugins

You get stock plugins right in your DAW, which tend to be more CPU-friendly. That makes them perfect for getting started or when the project needs you to spare CPU resources. They offer very solid foundational tools such as EQs, compressors, and reverb.

Pros:

  • Free and already included in the DAW.
  • Light, efficient, easy on resources.
  • Simple, easy to use, and accomplish basic tasks.

Cons:

  • Lack many features found in professional-grade plugins.
  • Lack in some respects the quality and depth of certain paid-for plugins.

Paid Audio Plugins

Paid plugins tend to have better sound quality, more features, and flexibility, giving the producer and sound designer further control. Examples of Diva Synth, SERUM, and Pro-Q3 are industry-standard plugins giving producers and sound designers a high degree of creative possibility.

Pros:

  • Better quality of sound and more developed features.
  • Often regularly updated, bugs fixed, and supported by their authors.
  • Specialized plugins for every production need.

Cons:

  • Can be expensive, especially for premium plugins.
  • May use more CPU power than stock plugins.
