1. What is Lossless Audio in Blu-ray Discs?
Lossless audio formats preserve the original quality of the studio recording, offering bit-perfect sound reproduction without compression losses.
Common Lossless Audio Formats in Blu-rays:
* Dolby Atmos – Object-based 3D surround sound for an immersive experience.
* DTS:X – Flexible 3D surround sound with positional audio.
* Dolby TrueHD – Uncompressed, high-resolution audio.
* DTS-HD Master Audio Studio-quality lossless audio for movies.
Why Lossless Audio Matters?
* Better clarity and dynamic range compared to compressed formats like AAC.
* Supports up to 24-bit/192kHz audio resolution for high-fidelity sound.
* Essential for home theater setups with AV receivers and surround sound systems.
2. System Requirements for Lossless Audio Playback
To enjoy Dolby Atmos and DTS:X audio from Blu-rays, ensure you have:
* iToolShare Blu-ray Player (supports bit-perfect audio passthrough).
* An HDMI 2.0 or higher connection (for uncompressed audio).
* A compatible AV receiver that supports Dolby Atmos/DTS:X.
