Description
Real-Time AudioSuite (RTAS) is a format of audio plug-in developed by Digidesign, currently Avid Technology for their Pro Tools LE and Pro Tools M-Powered systems, although they can be run on Pro Tools HD and Pro Tools TDM systems. RTAS plug-ins use the processing power of the host computer rather than DSP cards used in the Pro Tools HD systems. As the name suggests, the plug-in architecture is designed to be run in real-time, mimicking hardware inserts on traditional mixing console. This is in contrast to rendering files out of time with effects applied directly to the audio, which in Pro Tools is facilitated by AudioSuite Plug-ins. Avid's AAX format, which runs on both native CPU and Pro Tools HDX DSP, is the replacement for RTAS.

Oh.. RTAS plugs... less headroom?

Hi! I know this does not make sense but...

I was finishing a mix a few hours ago. As I were using plenty of plugs and was a little lazy to deactivate some so as to open the junior mastering plugs across the master fader, a strange thing happened:

At first, I had: Q10RTAS > TC MASTER X 5 TDM > Power Dither TDM > PAZ TDM
