Dolby DP600 Program Optimizer: Postproduction

Technical Paper

Dolby DP600 and DP600-C

Program Optimizer Overview for

Postproduction Facilities

The Dolby

DP600 Program Optimizer is an innovative audio platform that

provides a le-based work-ow solution for loudness correction, audio conversion,

and upmixing. The DP600 includes the world’s rst intelligent audio analysis and

automated loudness normalization engine, and the ability to encode, decode,

convert, and transcode Dolby Digital, Dolby Digital Plus, Dolby Pulse, and

Dolby E. It also features a newly designed algorithm for upmixing your legacy

two-channel audio for 5.1-channel delivery. These features, along with support

for many of the most common media le and audio formats in use today, make

the DP600 particularly well-suited for integration into your day-to-day le-based

postproduction work-ow environment.

For compressed audio formats that include metadata (Dolby Digital, Dolby Digital

Plus, Dolby Pulse, and Dolby E), the Dolby DP600 can automatically set the dialogue

normalization parameter or correct a previously set dialogue normalization parameter.

It can also perform loudness normalization on audio that does not contain metadata.

The DP600-C version of the Program Optimizer provides faster-than-real-time

le-based encoding and decoding of Dolby Digital, Dolby Digital Plus, Dolby Pulse,

Dolby E, MPEG-1 LII, AAC, HE AAC, and HE AAC v.2. Additionally, this version

enables multichannel audio conversion into and out of all of these formats, plus

PCM. The DP600-C can also perform highly ecient, single-step transcoding of

Dolby Digital to Dolby Digital Plus without having to decode and reencode.

An optional software upgrade adds an intelligent le-based upmixing capability for

customers interested in enhancing legacy two-channel audio for use in 5.1-channel

applications. This process is based on a newly developed Dolby algorithm which

creates a wider natural-sounding sweet spot and ensures that subsequent downmixing

is free from artifacts typically found with other solutions.

To ensure the highest possible work-ow integration and eciency, the DP600 oers

open access (via Web services) to Dolby’s unique audio processing engines as well as

coding technologies traditionally found only in real-time codecs.
