5 THE PRO-CODEC PLUG-IN
Dither
Only visible if the selected codec is HD-AAC. Only enable 16 or 24 bit dither if the
input to the plug-in has not already been dithered and truncated to either 16 or 24
bits.
Downmixing mode
Only visible if the selected codec is AAC-LC MPS or HE-AAC MPS. This allows you
to audition the various Fraunhofer downmixing algorithms. By default, no
downmixing takes place.
Note:
When auditioning a 2-channel downmixing mode, the DIFF signal will contain
content from the centre, surround and LFE channels, since the DIFF calculation
is done using the input and encoded signals.

Output Section
MONITOR
Indicates the plug-in’s audio output;
either
INPUT (ie. the plug-in is bypassed) or CODEC. You can
switch between input and codec output by clicking on the LEDs.
A special case for the mp3-HD codec, whereby the
MONITOR
signal is synthesized, is denoted by an INPUT 16 indication.
TOTAL DELAY
This window shows the total delay through the plug-in; click to
toggle between samples or milliseconds. The figure given is the
maximum of each individual codec delay. This field is updated
in the GUI immediately a new codec or other setting is selected.
Depending on the host behaviour, the new value may not
be available for delay compensation until the plug-in is removed
and re-instantiated.
RECORD
Writes the active codecs pre-selected for record-arm to disk.
Filename Format
This button calls up a pop-up used to configure the encoded file data.
