  • Dolby ATMOS: A 3D surround sound technology that provides immersive sound and envelopes the listener. This technology offers a revolutionary sense of depth and immersion in a home theater environment. Dolby Atmos is a flexible and scalable object-based format that reproduces audio as independent sounds (or objects) that can be dynamically positioned and moved in a 3D listening space during playback.
  • Dolby TrueHD: A high-quality audio technology developed by Dolby Laboratories that uses lossless encoding to faithfully reproduce studio master sound. This format supports up to 8 audio channels with a sampling frequency of 96kHz/24-bit resolution and up to 6 channels with a sampling frequency of 192kHz/24-bit resolution.
  • Dolby Digital Plus: An enhanced Dolby Digital signal format compatible with up to 7.1 channels, offering backward compatibility with traditional Dolby Digital. The increased data bit rate performance improves audio quality.
  • Dolby Digital: A digital signal format developed by Dolby Laboratories that supports 5.1 channel audio. Dolby Digital compresses each channel separately, allowing each channel's sound to be played independently without interference.
  • LPCM (Linear Pulse Code Modulation): One of the most fundamental codecs for digital audio, dedicated to uncompressed and lossless audio playback at 96kHz/24-bit.
  • PCM (Pulse Code Modulation): A method for converting analog signals into digital signals. It is one of the most commonly used methods for storing or transmitting audio data, making it easier to process and store data.
