DTS-HD Master Audio

DTS-HD Master Audio is an advanced lossless audio technology developed

for high-definition disc-based media including Blu-ray Disc. Selected as an

optional audio standard for Blu-ray Disc, this technology delivers sound

that is bit-for-bit identical to the studio master, offering a high-definition

home theater experience.

Supporting bitrates up to 24.5 Mbps for Blu-ray Disc, DTS-HD Master

Audio can carry up to 7.1 discrete channels of 24-bit/96 kHz audio

simultaneously. Supported by HDMI version 1.3 and designed for the

optical disc players and AV receivers/amplifiers of the future, DTS-HD

Master Audio also remains fully compatible with the existing multichannel

audio systems that incorporate DTS Digital Surround.

DTS Neo:6

Neo:6 decodes the conventional 2-channel sources for 6- channel playback

by the specific decoder. It enables playback with the fullrange channels

with higher separation just like digital discrete signal playback. There are

two modes available: “Music mode” for music sources and “Cinema mode”

for movie sources.

DSD

Direct Stream Digital (DSD) technology stores audio signals on digital

storage media, such as Super Audio CDs. Using DSD, signals are stored as

single bit values at a high-frequency sampling rate of 2.8224 MHz, while

noise shaping and oversampling are used to reduce distortion, a common

occurrence with very high quantization of audio signals. Due to the high

sampling rate, better audio quality can be achieved than that offered by the

PCM format used for normal audio CDs. The frequency is equal to or

higher than 100 kHz and the dynamic range is 120 dB. This unit can

transmit or receive DSD signals input from the HDMI jack.

FLAC

This is a file format for lossless audio data compression. FLAC is inferior

to lossy compression formats in compression rate but provides higher audio

quality.

MP3

One of the audio compression methods used by MPEG. It employs the

irreversible compression method, which achieves a high compression rate

by thinning out the data of hardly audible part to the human ears. It is said

to be capable of compressing the data quantity by about 1/11 (128 kbps)

while maintaining a similar audio quality to music CD.

MPEG-4 AAC

An MPEG-4 audio standard. As it allows compression of data at a bit rate

lower than that of MPEG-2 AAC, it is used among others for mobile

telephones, portable audio players and other low-capacity devices requiring

high sound quality. In addition to the above types of devices, MPEG-4

AAC is also used to distribute contents on the Internet, and as such is

supported by computers, media servers and many other devices.

LFE 0.1 channel

This channel reproduces low-frequency bass signals, and has a frequency

range from 20 Hz to 120 Hz. This channel is counted as 0.1, because it only

enforces a low-frequency range compared to the full-range reproduced by

the other 5-channels in Dolby Digital or DTS 5.1-channel systems.

PCM (Linear PCM)

Linear PCM is a signal format under which an analog audio signal is

digitized, recorded and transmitted without using any compression. This is

used as a method of recording CDs and DVD audio. The PCM system uses

a technique for sampling the size of the analog signal per very small unit of

time. Standing for “Pulse Code Modulation,” the analog signal is encoded

as pulses and then modulated for recording.

Sampling frequency and number of quantized bits

When digitizing an analog audio signal, the number of times the signal is

sampled per second is called the sampling frequency, while the degree of

fineness when converting the sound level into a numeric value is called the

number of quantized bits. The range of rates that can be played back is

determined based on the sampling rate, while the dynamic range

representing the sound level difference is determined by the number of

quantized bits. In principle, the higher the sampling frequency, the wider

the range of frequencies that can be played back, and the higher the number

of quantized bits, the more finely the sound level can be reproduced.

WAV

Windows standard audio file format, which defines the method of recording

the digital data obtained by converting audio signals. It does not specify the

compression (coding) method so a desired compression method can be used

with it. By default, it is compatible with the PCM method (no compression)

and some compression methods including the ADPCM method.

WMA

An audio compression method developed by Microsoft Corporation. It

employs the irreversible compression method, which achieves a high

compression rate by thinning out the data of hardly audible part to the

human ears. It is said to be capable of compressing the data quantity by

about 1/22 (64 kbps) while maintaining a similar audio quality to music

CD.

Sound program information

CINEMA DSP

Since the Dolby Surround and DTS systems were originally designed for

use in movie theaters, their effect is best felt in a theater having many

speakers designed for acoustic effects. Since home conditions, such as

room size, wall material, number of speakers, and so on, can differ so

widely, it is inevitable that there are differences in the sound that is heard.

Based on a wealth of actually measured data, Yamaha CINEMA DSP uses

Yamaha’s original DSP technology to combine Dolby Pro Logic, Dolby

Digital, and DTS systems to provide the audiovisual experience of a movie

theater in the listening room of your own home.

CINEMA DSP 3D

The actually measured sound field data contain the information of the

height of the sound images. CINEMA DSP 3D feature achieves the

reproduction of the accurate height of the sound images so that it creates

the accurate and intensive stereoscopic sound fields in a listening room.

Compressed Music Enhancer

The Compressed Music Enhancer feature of this unit enhances your

listening experience by regenerating the missing harmonics in compression

artifacts. As a result, it compensates for flattened complexity due to the loss

of high-frequency fidelity as well as lack of bass due to the loss of low-

frequency bass, providing improved performance for the overall sound

system.

SILENT CINEMA

Yamaha has developed a natural, realistic sound effect DSP algorithm for

headphones. Parameters for headphones have been set for each sound

program, so that accurate representations of all the sound programs can be

enjoyed on headphones.

Virtual CINEMA DSP

Yamaha has developed a Virtual CINEMA DSP algorithm that allows you

to enjoy DSP surround effects even without any surround speakers, by

using virtual surround speakers. It is even possible to enjoy Virtual

CINEMA DSP using a minimal two-speaker system that does not include a

center speaker.
