subject: Srs3d Audio Technology: Two Speakers To Create A Stereo-srs, Speakers, Audio Technology - Household [print this page] < BR> SRS is a U.S< BR> SRS is a U.S. company under the human auditory system SRSLabs Dynamics (DynamicsofHumanHearingSystem) Principles and psychological acoustics (Psychoacoustics) and patented audio technologies come up.
SRS is characterized by two speakers can be used to create a realistic stereo field, and this system applies to all two-channel audio source, including all stereo, surround sound, and even includes the source code to other systems. For single-channel audio source, SRSLabs company also has a three-dimensional simulation called 3DMono replay technology.

The human auditory system has been able to identify the source of space and direction, is due to the structure of the human ear by the arrival of sound in different directions have different frequency response, which by the arrival of sound in different directions with the human auditory system Change can be generated called "head-related transfer function (HeadRelatedTransferFunction, referred to as HRTF)" to make mathematical description. The human brain on the frequency response to these different voices heard to determine from the space in which location.
Recording technology uses the traditional structure of the human ear and a microphone for recording different. Although the sound from all directions of space with the information also is recorded, but the microphone did not like the direction of human space and recognition, the traditional two-channel system playback sound can not truly reproduce any original sound field .
SRS technology is the core way of compensation microphone recording the differences between the human auditory system. SRSLabs company from many years of study to master the human auditory system to identify the location of space in the direction of approach, which developed with HRTF-based SRS systems.
SRS in the traditional two-channel playback system with a microphone and the differences in the human auditory system of compensation to the original sound field information extracted from the recording, processing using proprietary technology, to restore. Sound field should be to reproduce the width and depth, more so that ordinary two-channel speaker system for the "point source (PointSource)" in tackling the problem, create a both broad and coherent sound field. This is the SRS (SoundRetrievalSystem, sound field reduction system) The reason behind the name.
In addition to using the SRS system real bright sound can be off-there are other advantages. Since the SRS has been treated with the direction of the sound itself, SRS does not rely on left and right channel speaker to listen to those voices to reach the ears of jet lag or phase shift to create three-dimensional effect. So can hear the stereo effect of the location of a very broad field, there is no general system limited to a small listening position of the state. Because of the same reasons, SRS placed on the speakers and listening environment, looser, less symmetrical in place even if still under the desired results.
In addition, SRS did not use the general so-called "sound field processing system," the usual delay, phase treatment, or other artificial simulation results, SRS is to create stability out of the sound field, the listener will not move or slightly rotating head and feel the sound field changes, not to the general simulation system caused by the serious tone and clarity down the end of dyeing problems. In sound quality, because SRS is based on characteristics of human hearing based on their own, not with any natural treatment, recording their fidelity can be preserved. At the same time because the SRS in the playback fidelity of the sound field should restore them, the effect of income can be said that a more natural sound.
SRS system for the use of the recording itself, the existence of information to restore the sound field into a replay through 2 speaker stereo sound, so for a variety of two-channel audio source. This includes a variety of two-channel recording and broadcasting, fully without any coding. Even if the source code is included in the surround sound system, SRS system used at the same time there will not be the case of conflicts, you can get a better sense of space and a more consistent sound field than the fruit.
In addition to two-channel audio source outside, SRSLabs also takes into account single-channel source of replay. SRSLabs of 3DMono (mono or mono-dimensional three-dimensional) system is for dual-channel mono audio replay system developed. Some of the old recordings, a part of the radio broadcast, or bilingual selection of films and with original music and karaoke VCD discs OK choice are common mono source.
SRSLabs the 3DMono system, using unique technology to single-channel is modeled as a two-channel effects, then SRS audio technology to bring information out of the sound field processing, creating a rich realistic stereo field. In addition to stereo effects outside the field, 3DMono Another feature is the stereo in the simulation to focus and maintain a strong low-frequency intervals, where no single-to dual-channel analog system in the common situation of low-frequency loose.
Present, SRSLabs the SRS and 3DMono technology has been in many countries the main audio-visual equipment manufacturers widely accepted, and is generally used in professional audio, home audio, and car stereos and other consumer electronic devices on.
