More Intel Rapid Storage Technology A floating-point format for frequency coefficients is used, and mantissas and exponents are stored and transmitted separately, with both being heavily compressed.

This tool is unique to Dolby Digital Plus and unsupported in Dolby Digital , and uses an additional Type II discrete cosine transform DCT to combine six adjacent transform blocks located within a syncframe into an effectively longer block.

In addition to the two-stage transform, a different bit-allocation structure is used, and two ways of representing encoded mantissas are deployed: use of vector quantization , which gives the highest coding gain, and use of gain-adapted quantization GAQ when greater signal-fidelity is required.

Gain-adaptive quantization may be independently enabled for each frequency bin within a channel, and permits variable-length mantissa encoding.

As many multichannel audio programs have high degrees of correlation between individual channels, a coupling channel is typically used.

High frequency information which is common among two or more channels is transmitted in a separate channel one that is not reproduced by a decoder, but only mixed back into the original channels known as the coupling channel; along with coefficients known as "coupling coordinates" that guide the decoder on how to reconstruct the original channels.

This algorithm, which is considerably more expensive to process both for encoders and decoders allows phase information to be included in coupling coordinates, allowing for phase relationships between channels that are coupled to be preserved.

Dolby Digital Plus provides another tool for high frequencies. As high frequency components are often harmonics of lower-frequency sounds, Spectral Extension SPX allows high frequency components to be synthesized algorithmically from lower-frequency components.

This is done both to increase coding gain the L-R channel can typically be heavily compressed, and the subsequent un-matrixing will cause many compression artifacts to cancel , and to preserve phase relationships necessary for proper playback of Dolby Surround -encoded material.

Transient pre-noise processing TPNP is a Dolby Digital Plus-specific tool to reduce the resulting artifacts of signal quantization and other compression techniques.

Unlike the other tools described above, which operate in the frequency domain and precede the conversion back into PCM samples, TPNP is a tool which essentially performs a windowed cut-and-paste operation on the time-domain signal to erase certain predictable quantization artifacts.

Dolby Digital Plus bitstreams are not directly backward compatible with legacy Dolby Digital decoders. AVRs, etc.

Note: All of the decoder operating modes listed above are available in every Dolby Digital Plus decoder.

The default operating mode is governed by device category and application. This is not problematic if the data is passed unchanged, but any gain scaling or sample rate conversion, operations which are aurally harmless to PCM data, will corrupt and destroy a Dolby Digital Plus stream.

Older codecs such as DTS or AC-3 are more likely to be recognized as compressed formats and protected from such processing. The combination of SMPTE and M allow the Dolby Digital Plus bitstream to be stored and transported within professional production, contribution and distribution workflows prior to emission to consumers.

Dolby Digital Plus is seeing increasing use in digital television systems, particular in cable and satellite systems, as a replacement for Dolby Digital.

Dolby Digital Plus, like many lossy audio codecs, uses a heavily quantized frequency-domain representation of the signal to achieve coding gain ; this section describes the operation of the base transform as well as various optional "tools" specified by the standard, which are used to achieve either greater compression or to reduce audible coding artifacts.

The frequency domain representation is then quantized according to a psycho-acoustic model and transmitted. A floating-point format for frequency coefficients is used, and mantissas and exponents are stored and transmitted separately, with both being heavily compressed.

Many such applications don't take advantage of its higher channel count or ability to support multiple independent programs; instead it is used as a higher-efficiency codec than AC The maximum number of discrete coded channels is the same for both formats: 7.

The complete audio track is allowed a combined bitrate of 1. During playback, both the core and extension bitstreams contribute to the final audio-output, according to rules embedded in the bitstream metadata.
