The SRS
TM
algorithm has been licenced from SRS Labs, Inc. The following is from an SRS Labs press
release:
SRS, the Sound Retrieval System, is based on the human hearing system. It produces a fully immersive,
three-dimensional sound image from any audio source with two or more standard stereo speakers.
Whether the signal is mono, stereo, surround sound or encoded with any other audio enhancement
technology, SRS expands the material and creates a realistic, panoramic sound experience with no “sweet
spot” or centered listening position. SRS is single-ended, requiring no encoding or decoding, and uses no
arti
fi cial signal manipulation such as time delay or phase shift to produce its natural, true-to-life sound
image.
The four SRS parameters control the ambience of the image, and may have different optimal settings
depending on the amount of stereo content in the inputs. To match the optimal settings speci
fi ed by SRS
Labs, the bass and treble gains should be set to 0 dB. This algorithm will have no effect on mono signals.
Parameters
Page 1
In/Out When set to “In” the effect is active; when set to “Out” the effect is bypassed.
Out Gain The overall gain or amplitude at the output of the effect. Out Gain is not applied to the
signal when the effect is bypassed.
Center The amount of “center channel” can be varied with this control.
Space The width of the image is controlled with this parameter.
Bass Gain The amount of ambience added to the Bass frequencies in the signals. A setting of 0 dB
gives a best match to the optimizations of SRS Labs.
Treb Gain The amount of ambience added to the Treble frequencies in the signal. A setting of 0 dB
gives a best match to the optimizations of SRS Labs.
In/Out In or Out Out Gain Off, -79.0 to 24.0 dB
Center Off, -79.0 to 24.0 dB Bass Gain -79.0 to 24.0 dB
Space Off, -79.0 to 24.0 dB Treb Gain -79.0 to 24.0 dB
