Dolby TrueHD is an advanced audio codec designed to deliver high-definition sound for home theater systems. It supports lossless audio, meaning that the sound quality is preserved exactly as it was recorded, providing an immersive listening experience. This technology is commonly used in Blu-ray discs and streaming services to enhance the audio quality of movies and music. One of the key features of Dolby TrueHD is its ability to support multi-channel audio, allowing for up to 7.1 channels of sound. This creates a surround sound experience that can make viewers feel as if they are part of the action. Dolby TrueHD is compatible with various devices, including AV receivers and soundbars, ensuring that users can enjoy high-quality audio in their home entertainment setups.
