THX is often confused with codecs like Dolby or DTS, but it is something completely different: a certification and quality standard.
THX: quality standard
Dolby/DTS: codecs
Purpose: accurate playback
THX certifies speakers, AV receivers, TVs, and even cinema systems to meet strict performance standards.
The goal is to ensure that what you hear at home is as close as possible to what was heard in the studio.
THX may include audio processing features like loudness management, crossover tuning, and spatial adjustments.
