Plug-In Formats

Pro Tools TDM software supports the following Plug-In formats:


Digidesign's Time Division Multiplexing (TDM) technology is the foundation of the Pro Tools professional mixing environment, providing 24-bit mixing and real-time digital signal processing (DSP) capabilities. TDM Plug-Ins use the dedicated hardware of TDM systems, which offer easy expandability — you can add TDM plug-ins up to the DSP capacity of your system, no matter how many edits or how much automation you have in a session. If you need more DSP, simply add another DSP Farm or MIX Farm card.


Host Time Division Multiplexing (HTDM) Plug-Ins represent a hybrid of TDM and RTAS technologies. HTDM Plug-Ins provide all the logistical functionality of standard TDM Plug-Ins, but, like RTAS Plug-Ins, they allow for all the processing to be done on the host. In so doing, HTDM Plug-Ins offer two primary benefits: The resources of the Pro Tools Core and/or Farm DSP chips remain available for other tasks; and, despite running on the host, HTDM Plug-Ins can be instantiated on any track, a characteristic previously confined to TDM Plug-Ins only. HTDM Plug-Ins will only work with the following systems:

  • Pro Tools|HD systems for Macintosh or Windows XP
  • Pro Tools MIX systems with Pro Tools 5.1.1 for Macintosh or higher
  • Pro Tools MIX systems for Windows XP and Windows 2000 with Pro Tools 5.3.1 or higher

Real-Time AudioSuite (RTAS)

Real-Time AudioSuite Plug-Ins are host-based processors, using the computer's processing power to do their job. Functionally, RTAS Plug-Ins offer many of the real-time benefits of TDM Plug-Ins. They are fully automatable, their parameters can change in real time, and their effects are not permanently written to the audio file. Since they are host-based, RTAS Plug-Ins require trade-offs between track and plug-in count, edit density and amount of mix automation in a session.


AudioSuite Plug-Ins provide file-based processing, meaning they process or alter the sound file and create a new file with the processed sound. The resulting effect is applied to the entire file. AudioSuite Plug-Ins are great for conserving DSP power and certain types of processing where there is no real-time benefit or application, such as normalization and noise reduction.
