It is possible with some hosts to render the mix to wav at the same time as online encoding;
the codec might be inserted into an ‘aux’ channel for this. If the plug-in is in the master
output channel, you will almost certainly not want to render the plug-in monitor output. Put
the plug-in into bypass to render to wav, then either offline encode or use a second pass to
online encode.
If the targets are both a compensated wav and a bitstream for a single codec, then it’s best to
trim the input level (not the bitstream trim level) and use online encode while bouncing down
to wav. An alternative here would be to additionally encode to a lossless codec rather than
wav.
If many different codec files are required with no optimisation for any given
codec/bitrate/quality combination, then offline encode is appropriate from a rendered master
wav. To ensure the bitstreams are perfectly encoded to avoid decoded bitstream overloads,
use the Offline Encode tab with either the ‘Normalise Decoded Level’ or ‘Prevent Decoded
Levels > 0dB’ options (these options are not available in online mode).
Finally, on-line encoding should be avoided if many processor-intensive codecs are selected.
4.7 Codec and Encoded File Sample Rates
The sample rate of an encoded file is derived from the session sample rate, the codec
supported sample rates, the selected codec bitrate, the selected codec quality setting and the
channel configuration. Hence, it is not a simple process to choose a desired encoded file
sample rate. The codec sample rate is shown in the Offline Encode CODEC & SETTINGS
status window.
The following tables give examples of the encoded file sample rate that result from various
selection conditions (full tables can be found in Section 10 of this manual — Specifications).
The codecs have an internal ‘preferred sample rate’, which will give the highest quality
reproduction (but, quite frequently, higher CPU usage).
In general, if the highest quality setting is selected for a codec, then the encoded file will have
the sample rate as listed in the ‘Preferred Sample Rate’ column (matching the session sample
rate, if this option is available).
