PROCESSING AUDIO
56
Crop Loop
DD
DD
Crop Loop allows you to trim files, by removing all audio data out-
side the left and right locators.
If you have set up a perfect loop with the locators, and the file contains audio
outside this locator range you can use Crop Loop to remove this superfluous
data.
Remove DC
This function will remove any DC offset in the audio. DC offset is when there is
too large a DC (direct current) component in the signal, sometimes visible as the
signal not being visually centered around the “zero level axis”. DC offset can in-
troduce clicks if the slices are later moved around in a sequencer, and it also af-
fects zero crossing detection (see page 47) and certain processing functions
such as Re-Analyze and Normalize.
Re-Analyze
Re-Analyze re-runs the slice-detection algorithm on the waveform data. You may
have deleted slices that were detected when the file was first sliced. This com-
mand will ”re-discover” those slices.
DD
DD
Re-Analyze will add all slices to positions in the file not already
occupied by other slices.
Note that the added slices may not be visible, as this depends on the Sensi-
tivity setting!
Additional Processing
Items
There are a number of additional real-time processing items available on the
Toolbar (Preview mode must be activated):
Processing Gain
This function allows you to change the gain (volume) of the loop. The applied
gain change will be present when the loop is saved or exported.
The main use of this function is to compensate for possible clipping or level
changes introduced by other processing items, like equalization for example.
DD
DD
You can boost the gain by up to 18 dB, or lower it down to silence
(-80 dB).
You should avoid boosting the signal to the extent that the Level Meter clip
indicators light up often. If they momentarily light up once, you should listen
carefully to see if it sounds ok (a slight amount of clipping on percussive ma-
terial is not necessarily even noticeable). The final judge is your ears!
Gate Sensitivity
Gate Sensitivity could be described as a type of noise gate. It is triggered
(opened) by every active slice start, and closes for any material (in each slice)
that falls below a set threshold. When you set the Gate Sensitivity so that the
end part of the slice(s) fall below the threshold, the gated part of the waveform
will be greyed out. The “gated out” material is not exported.
This function has three primary uses:
DD
DD
It can be used to remove part of a file that contains silence, for ex-
ample in conjunction with Silence Selected (see page 76).
By removing “silent data”, the size of the exported data is reduced.
DD
DD
It can be used if you have a file with several individual sounds con-
taining “air” in between the sounds, and want to save each one as a
separate file.
This also keeps the size of the exported data down.
DD
DD
It can be used for special effects, e.g. abruptly chopping off a reverb
tail.
Preview Pitch
You can change the pitch of a loop up or down two octaves (+/- 24 semitones).
Hold down [Command] (Mac) / [Ctrl] (Win) and click the Pitch knob to reset the
pitch back to original. Hold down [Shift] for adjusting values in finer increments.
Preview Tempo
You can change the tempo of the loop. Tempo values between 20 to 450 BPM
can be set using the Tempo knob or by typing directly in the Tempo box and
pressing [Enter].
Hold down [Command] (Mac) / [Ctrl] (Win) and click the Tempo knob to reset
the tempo back to the original. Hold down [Shift] for adjusting values in finer in-
crements.
