HD-AAC input using the internal dither/truncation
The bit-meter indicates that there is no activity in bits greater than 24. The input to the codec
is correctly dithered and truncated. The border for the bottom segment is green to indicate
that the dither/truncation is provided internally.
HD-AAC input dithered and truncated twice
Here a correctly dithered/truncated signal enters the plug-in, but the internal dither is also
applied. One of the operations is redundant, and this is indicated by a red border round the
bottom segment.
Furthermore, there is a situation when it is desirable to use the internal dither/truncation, even
if the signal presented to the plug-in input is correctly treated.
This case is when the lossy core has been observed to cause overloads on decode, and the
remedy has been to use the internal trim control. Here, the trim is applied internally to the
plug-in, and any external dithering is not helpful. The signal should be dithered using the
internal dither option.
