SAMPLING: Page Menu Commands Normalize/Level Adjust

Normalize/Level Adjust
This command uniformly modifies the data values (volume)
of the data between the
Start – End . Normalize will amplify
the level of the sample data as far as possible without
allowing it to clip (distort). If the level of the sampled data is
too low, you can execute this command to increase the
dynamic range.
Level allows you to raise or lower the level
as desired.
1. Use Sample Select (1–1b) to select the sample that you
wish to edit, and use Start and End to specify the
editing range.
You can press the SAMPLING START/STOP button or
Play button to hear the portion that will be normalized or
level-adjusted.
2. Select Normalize/Level Adj. to open the dialog box.
3. The range to be edited is shown by Range Start and
End .
4. If you check Normalize and execute, the data will be
normalized. In this case, the Level setting will be
ignored.
If you wish to specify Level to modify the level of the
sample data, do not check Normalize .
Each increase of +6 dB will approximately double the
height of the waveform shown in the LCD. +12 dB will
be an increase of approximately 4X, and +18 dB will be
approximately 8X. Conversely, each decrease of –6 dB
will halve the level, so that –6 dB will be 1/2X and –12
dB will be approximately 1/4X. Executing the
Level
command with positive (+) settings may cause the sound
to clip (i.e., distort at the point that amplification beyond
the maximum level is impossible). Once the sample data
has been boosted beyond the clipping point, re-executing
this command with negative (–) settings of
Level will
simply lower the overall level of the clipped signal –the
waveform will remain distorted.
Also, if executing
Level with negative (–) settings causes
any portion of the sample data to reach a zero level, the
zero data will not return to its original state even if you
re-execute
Level with positive (+) settings.
5. In Save to No., specify the save destination sample
number. By default, an unused sample number will be
selected.
If Overwrite is checked, the sample number will be fixed
to the current sample, and cannot be changed. See “About
Overwrite” on page 605.
For stereo samples, use “Save to No.(L)” and
“(R)” to specify the save-destination of the L and R
channels.
6. To execute the Normalize/Level Adjust command,
press the OK button. To cancel, press the Cancel
button.
Be aware that if sample data of an extremely low level is
normalized, any noise included in the sample will also be
amplified.
Volume Ramp
This command modifies the data values (volume) between
the
Start and End . You can make the volume gradually
increase (Fade In) or decrease (Fade Out) from the Start to
the End .
1. Use Sample Select (1–1b) to select the sample that you
wish to edit, and use Start and End to specify the
editing range.
You can press the SAMPLING START/STOP button or
Play button to hear the portion on which “Volume Ramp”
will be executed.
2. Select “Volume Ramp” to open the dialog box.
3. The range to be edited is shown by Range Start and
End .
4. Use the radio buttons to select the type of volume
ramp.
Fade In:
The volume at Range Start will be zero, and
will gradually increase toward End .
Fade Out: The volume will gradually decrease from the
Range Start volume until it reaches zero at End .
5. In Curve, specify the way in which the volume will
change.
Linear:
The volume will change linearly. For normal
fade-in or fade-out, select Linear.
