SRS stands for Sound Retrieval System, which means a sound recovery system that reproduces the real three-dimensional sense of the scene. It is the sound technology patent of the American SRS laboratory.
SRS 3D Surround Sound Processing Technology SRS 3D is a speaker system that produces a rich three-dimensional spatial sound field based on the human ear effect. The SRS 3D system has been introduced in the previous article, and its principle is not repeated here.
The SRS 3D's eye-catching feature is the ability to play Dolby Surround encoded sources as well as normal stereo sources, as well as input mono audio signals for processing, then paired with a stereo amplifier. Create a three-dimensional surround sound stereo field with a sense of space for the speakers.
The biggest difference between the SRS 3D two-channel surround sound system and the Dolby Surround system is that the direction of Dolby research is multi-channel surround. The multi-channel system must be encoded and processed to record the desired audio information. It is then restored to the original multi-channel audio signal with a dedicated decoder, and then the multi-channel amplifier and multi-channel speakers (speakers) can reproduce the real sound field. The main direction of SRS 3D is two-channel surround, no encoding program, directly processed by the internal circuit into the required audio signal, as long as the ordinary two-channel power amplifier plus two speakers can simulate the three-dimensional surround sound field effect This cannot but be said to be the advantage of SRS 3D.
SRS TruSurround Technology SRS TruSurround (qualified virtual surround sound) is another virtual surround sound processing system introduced by SRS Labs in the United States in 1997. It is specifically developed for multi-channel playback systems such as Dolby Pro-Logic, Dolby Digital Surround (AC-3), and THX Home Surround. The multi-channel audio signals decoded by the above-mentioned various types of dedicated decoders are processed by SRS TruSurround and output from two independent channels. The SRS TruSurround processing feature preserves the original multi-channel audio information from these sources, thereby creating an additional illusion source that gives the listener a richer surround sound field than the SRS 3D.
Although SRS 3D has been widely used successfully, the 3D stereo effect created by only two-channel processing is still slightly worse than the multi-channel playback system. In order to make up for its shortcomings, SRS Lab conducted an in-depth discussion to determine the optimal HRTF computing technology to simulate real multi-channel surround sound. Therefore, the technical difficulty of SRS TruSurround is much larger than that of SRS 3D, and its multi-channel processing method is more complicated than two channels and has a large amount of computation.
The surround sound illusion sound field created by the sophisticated technical processing in the SRS TruSurround system is deeper and wider than the SRS 3D. It forms an overlapping illusory sound source around the listener. If the SRS TruSurround processed audio signal is used to drive 6 speakers, the surround sound field will be further enhanced and the position of the listening sound will be loose.
Another distinguishing feature of SRS TruSurround is its compatibility with Dolby Surround, Dolby Pro-Logic, Dolby Digital AC-3 Surround, THX Home Surround and 3D-processed audio sources, and DTS and MPEG-2 audio system. Even a normal stereo sound source, with SRS TruSurround technology, can also achieve a very good surround sound field effect.
Given the powerful compatibility of the SRS-qualified virtual surround sound system, its range of applications is broader than that of the SRS 3D. SRS TruSurround is especially suitable for AV home theaters, DVD players, DVD-ROM discs, MPEG-2 systems and multimedia computers.
Currently using the SRS-qualified virtual surround sound system, the second-generation DVD player (DVD-L9/909, DV-S9) from Japan Pioneer, and the latest FD Trinron XBR high-end luxury large-screen color TV released by Sony (Sony) First introduced SRS TruSurround technology in audio systems.
