7.3.1 Encoding
The
ClipSafe button enables a level-correction feature. This works by decoding the
newly compressed file, calculating the maximum sample value in the PCM stream and, if
necessary, applying the precise amount of gain trim required when the source file is
encoded a second time. This guarantees that the final encoded file, once decoded for
playback, will not contain any illegal sample values (or overloads). However, if your audio
files have been correctly prepared using the Pro-Codec Plug-in, using
ClipSafe should
not be necessary.
NORMALISE can be enabled in addition to ClipSafe in order to ensure that the
post-decoder level of the encoded file is as close to 0 dBFS as possible.
If the
Normalise button is enabled, the source file is encoded, then decoded and the
maximum sample value is found. The source file is then re-encoded with a gain
adjustment to force the decoded max value up or down to 0 dB.
When you are ready, press the
Encode button to encode the file and write it to the target
location. A status bar will indicate progress during the encoding process. During
encoding, it is possible to press the encode button again if you wish to cancel the
process.
Note:
The current status of the process is also indicated in the
Status tab at the bottom right
corner of the Manager.
All edited tags in the
MetadataEditor will be written to the encoded output file.
Some computers may indicate a ‘spinning progress cursor’ during the first few seconds
of the encoding process. This is quite normal and does not indicate that the application is
not responding.
