The long-awaited replacement for HD Accel came up as HDX with upgraded Field Programmable Gate Array (FPGA) enabled cards and a new Avid Audio eXtensions plugin format that can run on both native (AAX) and accelerated (AAX-DSP) technologies. As an example, an HD3 system consisting of one core card, two Accel cards, and six Digidesign 192 blue interfaces could accommodate 96 inputs and outputs. HD2 through HD7 use additional Accel cards to increase the amount of TDM processing as well as track and voice count.Įach card on the system can accommodate 32 inputs and outputs via the Digidesign 192 blue interfaces. The most basic configuration (HD1) only uses a core card to host the mixer and I/O it can also provide some TDM processing power. Real Time Audio Suite ( RTAS) can also be used with this system, but as I will explain later on, should be used in a particular order alongside TDM ones. Its DSP chips can run specially coded TDM plugins, but its delay compensation engine is limited to a maximum of 4095 samples. Pro Tools HD Accel operates at 24-bit for TDM plugin processing with a 48-bit, fixed-point summing engine. Even if it is now technologically unjustified, its quality and studio presence are still current, and since you can still use it with PT10 (PT11 does not support it anymore), we should discuss it. You can have up to seven cards per computer for an HD7. It became very expensive because the user would need to purchase many additional cards to achieve a comfortable amount of processing power. The audio industry flagship for many years, Pro Tools HD Accel is a DSP-based system using Time Division Multiplexing ( TDM) coding. This guide shows you the framework to enable you to take your usage of ProTools to the next level by explaining and discussing new and advanced features to achieve industry standard techniques. Finally, you will see how you can export your project safer, faster and better. You will then learn editing using Beat detective, as well as covering excellent workflow and routing concepts to take full advantage of ProTools mixing capabilities, integrating both hardware analogue units with your favorite plugins. When it comes to choosing a ProTools HD system there are different technologies available and therefore, many ways to use the system optimally so, you will learn about some digital audio concepts for better software optimisation.
