Advanced users can thus record files conforming to regional standards or personal preference, substantially
reduce the possibility of audio clipping in recorded files, and even adjust the level on the fly if necessary.
The main point to remember from all of t his is that for digital audio recording “less is often more”. When it
comes to levels, by all means go as high as necessary – but it’s equally practical to go no higher than necessary.
Hint: The Audio Mixer also provides Compressor/Limiters for each input and output. These can also be
invaluable in defeating clipping due to over-modulation.
16.9.2 STREAM
Level controls for the stereo audio that accompanies Streaming outputs are provided in the Output
Configuration panel (see Section 8.2).
SECTION 16.10
ADVANCED CONFIGURATION
The controls for all inputs (including internal
audio sources) as well as the
Effects , Stream , Aux
and Master output groups include a configuration
button shown when you move the mouse over the
input label.
T he familiar ‘gear’ icon opens the advanced Audio
Configuration panel. We touched on this panel
briefly when we discussed selecting and
configuring
Connections for external audio inputs.
The Audio Configuration panel (Figure 202) offers
many more important features and controls,
however. Let’s explore these now.
16.10.1 INPUT TAB
A UDIO D ELAY
Audio and video arriving at inputs in sync will
maintain sync throughout the system to output or
recording. However, you should note that
upstream issues can cause video to arrive at system
later than the corresponding sound.
To mitigate this sort of external problem, the
Audio Mixer provides an adjustable
Audio Delay
feature.
E.g., many cameras support simultaneous digital and analog audio output. In-camera processing can delay
digital a/v output, resulting in analog audio output actually leading the digital output by a meaningful
measure.
