■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 Surround™ 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

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.
