Once decoding has finished, the filename text reverts from red to black, and the output
filename box shows a green highlight. This file can then be dragged directly to your host
sequencer (Windows only).
4. Additional Information on Workflows
4.1 Processing Sequence
The concept underlying the development of this plug-in is was that it should be the very last
item in the mastering chain. A 16 or 24-bit master has been finalised and possibly rendered to
a wav file. What is now required is to take that finalised master and produce an encoded,
data-compressed version (or versions) for end-user playback.
In other words, the mix would normally be fed via a limiter to control peaks, and then dither
would be applied before the data is truncated and written to the 16 or 24-bit wav master.
Again, under normal circumstances, this wav file would be passed via an encoder to derive a
final mp3 or AAC file for end-user distribution.
However, please note that this final step is not necessarily carried out currently by the
mastering engineer. Frequently, only the wav file (or losslessly encoded audio) is sent to the
distributor or aggregator. This means that the mastering engineer has no control over which
encoders are used, which encoder parameters are used, or whether the final encoded file will
clip and/or distort when played back on a consumer device. Also, there is little point in
producing a mix optimised for a particular codec or bitrate.
The mastering engineer can now achieve this control by using the Pro-Codec plug-in. Each
mix can be auditioned exactly as the end-user will hear it; and consequently the mix can be
tuned appropriately by the mastering engineer for a selected codec.
It is important to note that the Pro-Codec plug-in should be used after the limiter-dither-
truncate process. If a dithered master wav file is required, it should be rendered with the plug-
in monitor set to input or with the plug-in bypassed.
