AM MENU
Dry Voice Detection Menu
Speech is one of the most difficult waveforms to process cleanly, as the human voice is complex in nature and is
typically asymmetrical in form. Stations that choose to process aggressively in an effort to maximize loudness may
find that bare vocals come through with unacceptably high levels of audible distortion.
The
Dry Voice Detection
menu houses the controls that allow Omnia.7 to overcome this by automatically detect-
ing (in the Auto mode) when the input audio is speech and using a separate set of multiband targets, attack rates,
and release rates. This allows the dynamics section to do more of the “heavy lifting” and reduces the amount of
clipping necessary to maintain the same level of loudness.
♦
Setting the
Speech
control to “Off” completely disables the speech detection circuit. “Auto” allows the
processor to automatically detect the presence of speech. “Force” overrides the main multiband settings
and uses the Speech Detection settings (as determined in the current preset) at all times. The default
setting depends upon preset chosen; most presets have this featured set to “Off” by default, while the
default setting for more aggressive, loudness-driven presets is “Auto.”
