LFE 0.1-channel

This channel is for the reproduction of low bass signals.

The frequency range for this channel is 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

reproduction by the other 5/6 channels in Dolby Digital or

DTS 5.1/6.1-channel systems.

Neural Surround

Neural Surround

represents the latest advancement in

surround technology and has been adopted by XM

Satellite Radio for digital radio broadcast of surround

recordings and live events in surround sound. Neural

employs psychoacoustic frequency domain

processing which allows delivery of a more detailed sound

stage with superior channel separation and localization of

audio elements.

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.

SRS TruBass is a psychoacoustic bass enhancement

technology developed by SRS Labs, Inc. for speakers and

headphone systems that delivers bass up to an octave

below the physical capabilities of the speaker's driver.

SRS TruBass technology takes advantage of a

spontaneous tendency of the human ears to infer low-

range audio data when presented with higher-frequency

harmonic signals. As a result, our ears can hear the

original low-range sound that the speaker system is

incapable of producing.
