6.8. Trim
This command leaves only the waveform in the selected region, and deletes
the portions of the waveform which lie before and after the selected region.
In the case of sound data with two or more channels, the [Trim] command can
be executed only if the selected region includes all channels.
*The deleted portion of the waveform will not be copied to the TWE
clipboard.
6.9. Mix
This command pastes the waveform which was copied to the TWE clipboard,
starting at the specified location in the waveform display.
Unlike the [Paste] command, the original data will be mixed with the pasted
data if the destination already contains waveform data.
The following four sub-menus are available.
<Add Over>
The waveform in the clipboard will simply be added onto the existing
waveform.
<Average>
After the processing of Add Over has been performed, the amplitude (volume)
of the mixed portion of the waveform will be halved.
<Normalize>
After the processing of Add Over has been performed, Normalize (100%) will
be executed on the mixed portion of the waveform. (For details on Normalize,
refer to "6.19. Normalize...")
<Crossfade>
A crossfade will be created by fading out the existing waveform and fading
in the waveform data pasted from the clipboard.
If the end of the waveform data pasted from the clipboard lies beyond the
end of the existing waveform, only the mixed portion will be crossfaded, and
for the portion that lies beyond this, the waveform from the clipboard will
simply be pasted without change.
Executing the [Mix] command will not affect the contents of the clipboard.
