![]() It is truly a best-of-all-worlds scenario. However, from my perspective, this latest opening up of the HDX cards, with the new HDX Hybrid Engine is nothing short of a giant gift from Avid for post-production power users like me who benefit from the advantages of the hardware but also want to take advantage of the native CPU power of modern computers. Modern native CPUs now run circles around the DSP capacity of even a 3-card array of HDX cards and in most cases, for everyday playback and production, HDX cards offer very little advantage over a purely native solution and in many cases are a hindrance, except when you need zero-latency recording and monitoring. The latest iteration from Avid - Pro Tools HDX was released in October of 2011, the HDX PCIe cards empowered Pro Tools users to run loads of DSP powered plugins, up to 192 IO channels, and up to 768 voices, which enabled professional audio users the ability to do pretty much anything they could imagine in pro audio.īut a decade is a long time in modern technology and what people can imagine doing has evolved significantly since 2011. ![]() However as we have all found, as CPUs have become faster and more powerful and the amount of RAM available has increased, more and more of the audio processing can be handled on the computer’s own processors, rather than shipping it off to dedicated processors." You can learn more in our History of Pro Tools - 1994 to 2000 article.Ĭompare that now to my 16-core Mac Pro with processors running at 3.2GHz, the difference is huge. That computer could run 16 tracks of audio with DSP powered plugins. For example, Mike Thornton reminded me that his first Pro Tools HD system was using Nubus cards running on a PowerPC 7100 Mac computer with a 66MHz clock. "In the early days of Pro Tools, DSP acceleration was essential in computer audio systems. ![]() As James Richmond wrote in his article Avid Pro Tools Hybrid Engine - Massive 2048 Voice Counts Are Coming… For many Pro Tools users, DSP-accelerated HDX cards are largely a solution that we needed when computer processors were nowhere near as powerful as they are now unless you need zero-latency recording and monitoring. ![]()
