THX modernizes its legendary Deep Note with a new Spark trailer

Anyone who regularly goes to the movies has encountered the Deep Note at least once, that highly recognizable electronic crescendo accompanying the logo of the sound specialist THX. In 2026, THX decided to modernize the trailer designed to promote this famous sound and, above all, the technology behind it. Spark: a 4K HDR10+ trailer designed for Eclipsa Audio technology. While it doesn't unveil any new technology, this trailer is certainly more modern than its predecessor. Compatible with 4K and HDR10+, Spark, as this trailer is called, can be enjoyed in optimal conditions on a device compatible with the new Eclipsa Audio technology. This is a good opportunity to recall that this competitor to Dolby Atmos technology was unveiled in early 2025 by Google and Samsung.
