The software was also used as decoders for SRS-coded, dynamic Microsoft Smooth Streaming in 5.1 surround sound for the Microsoft Silverlight - client used. Both programs install the SRS HDAudio Lab Service under Windows and integrate a virtual SRS audio device. The software mentioned is still very popular on the Internet and is widely available for download. The SRS Audio Essentials program with the Truvolume feature - in contrast to the SRS HD Audio Lab program - also offers a strong acoustic companding of the audio signal for the automatic adjustment of level differences within an audio file. In the practical test, if the parameters are carefully set using the SRS Audio Essentials or SRS HD Audio Lab software, there is a considerable tonal enhancement of inferior consumer boxes, the quality of which is characterized by pronounced resonances and nasal frequency humps due to the material and construction. Finally, the Circle Surround feature interpolates the stereo signal for playback on a 5.1 or 7.1 multi-channel system. The TruSurround feature combines the above features and makes use of the laws of the outer ear transmission functions : Further interventions in the phase position of the stereo signal by means of time differences and the generation of interaural level differences by manipulating the directional frequency bands result in phantom sound sources behind the head. With the TruBass feature, overtones are added to the bass, which - in accordance with a registration practice with church organs - generate psychoacoustic undertones that could not be produced by the loudspeaker system itself. In the practical test, this feature is virtually equivalent to a center speaker in a multi-channel system. The FOCUS (also Dialog Clarity ) feature effectively emphasizes the center signal in order to compensate for the acoustic hole between the loudspeakers and to restore the presence of, in particular, point sources of sound such as solo musicians. In addition, the feature effects a psychoacoustic expansion of the stereo basis in the stereo reproduction with two loudspeakers through frequency-dependent phase shifts. With the WOW feature, the bass signal in particular is expanded to counteract the acoustic compression from the production of the media and to restore the dynamics of the original sound source. The concept is the psychoacoustic expansion of the stereo basis for stereo reproduction with loudspeakers and headphones as well as the interpolation of a surround sound from the stereo signal for multi-channel surround sound reinforcement. , based in Santa Ana, California, and was discontinued under the brand name SRS when it was taken over by DTS, Inc., also from California, in 2012. It was developed by what was then SRS Labs, Inc. The Sound Retrieval System (SRS) is a proprietary technique of psychoacoustic audio signal processing on electronic consumer devices such as televisions, cell phones and computers. ![]()
