MLP Lossless, an audio compression technology for DVD audio, delivers stereo and multichannel sound that exceeds conventional CD audio quality.
MLP Lossless™ enables producers to encode up to six channels of 96 kHz/24-bit audio or two channels of 192 kHz/24-bit audio onto a DVD-Audio disc.
Because the audio is bit-for-bit identical to the studio master, MLP Lossless ensures that you hear exactly what the producer intended.
DVD-Audio takes your home audio system up a notch with sound quality that exceeds what's possible on conventional CDs. By combining DVD technology with MLP Lossless audio coding from Dolby, DVD-Audio discs can deliver music with full 5.1-channel surround sound and exceptional fidelity.
Unlike perceptual or "lossy" compression technologies, MLP Lossless makes no alterations to the final decoded signal. Rather, it simply packs the audio data more efficiently for easier transmission.
On the receiving end, MLP Lossless unpacks easily, so the original signal can be enjoyed with bit-for-bit accuracy. That means you hear the performance exactly as its creator intended.
While all DVD-Audio players are equipped with MLP Lossless decoding, its use on the discs themselves depends on the producer's discretion.
Dolby® Digital Plus™ delivers a definitive surround sound experience for all your devices from home theaters to smartphones.
