DP564 Multichannel Audio Decoder Appendix A: Metadata

A-18

Note: The parameters DC Filter, Lowpass Filter, LFE Lowpass Filter, Surround

3 dB Attenuation, and Surround Phase Shift appear after the Extended BSI

parameters on Dolby E and Dolby Digital equipment menus.

DC Filter

This parameter determines whether a DC blocking 3 Hz highpass filter is applied to

the main input channels of a Dolby Digital encoder prior to encoding. This parameter

is not carried to the consumer decoder. It is used to remove DC offsets in the program

audio and would only be switched off in exceptional circumstances.

DC Filter Setting

Enable

Disable

Lowpass Filter

This parameter determines whether a lowpass filter is applied to the main input

channels of a Dolby Digital encoder prior to encoding. This filter removes high-

frequency signals that are not encoded. At the suitable data rates this filter operates

above 20 kHz. In all cases it prevents aliasing on decoding and is normally switched

on. This parameter is not passed to the consumer decoder.

Lowpass Filter Setting

Enable

Disable

LFE Lowpass Filter

This parameter determines whether a 120 Hz 8th order lowpass filter is applied to the

LFE channel input of a Dolby Digital encoder prior to encoding. It is ignored if the

LFE channel is disabled. This parameter is not sent to the consumer decoder. The

filter removes frequencies above 120 Hz that would cause aliasing when decoded.

This filter should only be switched off if the audio to be encoded is known to have no

signal above 120 Hz.
