What is thx?

THX is a high-fidelity audio reproduction standard originally developed by Lucasfilm in 1983. While not strictly a recording format, THX certification guarantees a specific level of audio and video quality for playback devices, speaker systems, and even cinema acoustics.

The core idea behind THX is to ensure that the audio and video experience in a cinema or home theater closely matches the creator's original intention. This involves rigorous testing and calibration of equipment and environments. THX specifications address various aspects of audio performance, including frequency response, distortion, noise levels, and sound pressure levels. Similarly, the video aspect ensures color accuracy, brightness, and contrast.

Over the years, THX has expanded beyond cinema sound systems to include home theater components, car audio systems, and even video games. THX certification can be found on a wide range of products, from AV receivers and speakers to projectors and TVs.

It's important to understand that THX is not a codec or an audio format like Dolby Atmos or DTS:X. Instead, it's a quality assurance standard. Products bearing the THX logo have been tested and certified to meet certain performance criteria, ensuring a high-quality audio and video experience. The company was acquired by Razer Inc. in 2016.
