The one feature that doesn’t get talked about much with the Storm is their Storm XT. See full description below... but basically what it does is if a speaker is outside of the supported speaker format, it will use that speaker by combining/matrixing it from the nearby speakers. For example, if you use a VOG speaker which will be active for DTSX Pro, and Auro, it would normally be silent when used for Atmos. However, with StormXT it will be active even with Atmos content. Same goes for speakers like Center Height. Another example is the front wides. Currently with the Storm implementation of Dolby Surround Upmixer, FW speakers were not active. But with StormXT they now are. This is something that Trinnov isn’t doing that I know of and is a very nice feature.
StormXT – Beyond natively decoding a large number of channels, with the multiple formats available on the market and their different recommended speaker placements, it is not uncommon to have silent speakers when playing certain content. While this can be a choice, it can be frustrating not to use all speakers to improve immersivity. StormAudio engineers have been working on this challenge and developed a proprietary engine called StormXT that works hand in hand with existing upmix algorithms to extract relevant audio signals from nearby speakers and redirect them to silent speakers. This new feature will be coming to the ISP platform free of charge in 2021.
