Chapter 6:
Menus: Audio Setup
SDI and DV inputs will be converted to the specified sample rate (except in
DigiDuplex mode), but SDI audio embedding will not function. The sample rate is
forced to 48 kHz when 96kHz AES Output mode (detailed earlier in this section) is
enabled.
The Sample Rate setting affects the valid range of the Test Freq-L, Test Freq-R, and
Fixed Delay options (detailed earlier in this chapter).
SDI Embedding
Enables or disables embedding of digital audio into the SDI data stream. When
enabled, the channels of the SDI video output into which the audio is embedded are
determined by the SDI Out option detailed earlier in this section.
Valid Settings: Off, On
Default Setting: On
Related Setting: SDI Out
NOTE: SDI embedded audio is not supported when the Dolby-E (Data) Mode
(detailed later in this chapter) is enabled.
SDI L/R De-Embed
Selects between interpretations of the SDI specification for embedded audio, to
compensate for variations in SDI audio implementation (how left and right are found
in the data stream). This setting should be left at the default unless compatibility
problems occur.
Valid Settings: Normal, Strict
Default Setting: Normal
Pitch Change
Controls the rate of frequency (pitch) change introduced by the system while delaying
the audio.
Valid Settings: Fast, Normal, Slow
Default Setting: Normal
Related Settings: Auto Track, Fixed Delay
The Slow setting corresponds to 0.54% (1/64 tone) pitch change for Auto Track delay,
and 6.67% for Fixed Delay.
The Normal setting corresponds to 1% pitch change for Auto Track delay, and 10%
for Fixed Delay.
The Fast setting corresponds to 1.5% pitch change for Auto Track delay, and 20% for
Fixed Delay.
Mute In Freeze
Specifies whether or not audio output should be muted when the incoming video is
frozen in Frame or Field mode (see Chapter 5, “Menus: Video Setup”).
Valid Settings: On, Off
