Music

The Dolby name was originally recognized for its success in engineering effective noise reduction technologies that complemented music reproduction and made possible an entirely new music delivery business based upon the compact cassette.

Cassettes

In the 1960s, Dolby A and B noise reduction technologies revolutionized cassette recording and listening. Learn more about these technologies in our Technical Library.

DVD-Audio

Widely recognized as the successor to the compact disc, DVD-Audio makes your home audio system sound like a live musical performance. DVD-Audio combines DVD technology with MLP Lossless™ coding from Dolby Laboratories to give you music with full 5.1-channel surround sound and fidelity that sounds identical to the original performance.

MLP Lossless is the core technology of Advanced Resolution® stereo and multichannel DVD-Audio. MLP Lossless enables content providers 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, resulting in playback that is bit-for-bit identical to the studio master. Nothing is lost during the encoding and decoding process.

A DVD-Audio player will provide the ultimate listening experience for DVD-Audio discs, but any DVD-Video player can also play DVD-Audio discs.

Listen to Dolby's Craig Eggers, one of the industry's leading experts, talk about how to best listen to music in surround sound and his favorite music on our biweekly podcast, Dolbycast.
