This command maximizes the dynamic range of a Wavesample. Normalize gain
always works on the currently selected Wavesample (selected on the EDIT page)
and has no parameters. It will make the sound louder, unless it is already at full
level. Normalize gain finds the largest sample value, and uses that to scale the
whole range of the sample to its absolute full level
Volume smoothing works like a dynamic compressor. The idea is to remove
amplitude changes. The degree to which it does this is determined by
"smoothness." It works on a given range of sound, determined by the start and
end address parameters. This command is very useful for smoothing out a loop,
and getting rid of clicks caused by volume bumps.
For instance, if you are working with a piano loop, there is a natural envelope that
is always decaying. If you try to loop on the section that is decaying, the loop
end data will be at a much lower amplitude than the beginning. You would end
up with a click, because of an abrupt change in amplitude. Volume Smoothing
will help make the level constant. When the EPS-16 PLUS displays DATA
RANGE TOO SMALL, it is advising you that the minimum range to do this
command is 256 Samples.
This command is most useful for loops, but you can use it on the whole sample.
If you wanted to remove a natural envelope from a piano, for example, you can
use volume smoothing over the whole length of the sample. You can then
superimpose any amplitude envelope from the EPS-16 PLUS over that sample.
SCALEDEPTH=3.0 to 6.0dB. SMOOTHNESS=VERY FINE to VERY
COARSE.
• Select VOLUME SMOOTHING. Press Enter•Yes.
• The display reads USE LOOP FOR RANGE? Press Enter•Yes to
automatically set the start and end addresses to the loop points.
• Select START ADDR=## (##). Use the Left/Right Arrow buttons to
scroll through the various screens. Use the Up/Down Arrow buttons to
change the values in the display.

DEPTH=##DB. Scroll to and select the SMOOTHNESS=####. Press
Enter•Yes.
• Select KEEP=OLD NEW. Press Enter•Yes to complete the command.
• Pressing Cancel•No for USE LOOP FOR RANGE? lets you adjust the start
and end addresses manually.
