In the context of beatmaking and music production, AAX refers to Avid Audio eXtension, which is a plugin format developed by Avid Technology, the company behind Pro Tools.Here are some key points about AAX:
- Plugin Format: AAX is a proprietary audio plugin format designed specifically for use with Pro Tools software.
- Successor to RTAS and TDM: AAX replaced the older RTAS (Real-Time AudioSuite) and TDM (Time Division Multiplexing) formats that were previously used in Pro Tools.
- Types of AAX:
- AAX Native: Runs on the host computer’s CPU
- AAX DSP: Runs on Avid’s dedicated DSP hardware (like HDX systems)
- AAX AudioSuite: For offline processing
- Improved Performance: AAX was designed to offer better performance and lower latency compared to its predecessors.
- 64-bit Support: AAX plugins support 64-bit processing, allowing for improved audio quality and more efficient use of system resources.
- Wide Adoption: Many third-party plugin developers now offer their effects and virtual instruments in AAX format to ensure compatibility with Pro Tools.
- Pro Tools Exclusivity: AAX plugins typically only work within Pro Tools, which can be a limitation for producers who use multiple DAWs.
For beatmakers and producers who use Pro Tools as their primary digital audio workstation (DAW), AAX plugins are essential tools for adding effects, processing audio, and using virtual instruments in their productions. However, those working with other DAWs will generally use different plugin formats like VST, AU, or RTAS.
