Audio menu
Process
Basically, you apply audio processing by making a selec-
tion and selecting a function from the Process submenu.
For details about the functions and parameters in the vari-
ous processing dialogs, use the Help button in the corre-
sponding dialog.
Envelope
The Envelope function allows you to apply a volume enve-
lope to the selected audio.
Fade In/Out
Allows you to set fade-ins and fade-outs.
Gain
Allows you to change the gain (level) of the selected audio.
Merge Clipboard
This function mixes the audio from the clipboard into the
audio selected for processing, starting at the beginning of
the selection.
For this function to be available, you need to have cut or
copied a range of audio in the Sample Editor first.
Noise Gate
Scans the audio for sections weaker than a specified
threshold level, and silences them.
Normalize
The Normalize function allows you to specify the desired
maximum level of the audio. It then analyzes the selected
audio and finds the current maximum level. Finally it sub-
tracts the current maximum level from the specified level,
and raises the gain of the audio by the resulting amount (if
the specified maximum level is lower than the current max-
imum, the gain will be lowered instead). A common use for
normalizing is to raise the level of audio that was recorded
at too low an input level.
Phase Reverse
Reverses the phase of the selected audio, turning the
waveform “upside down”.
Pitch Shift
This function allows you to change the pitch of the audio
with or without affecting its length. You can also create
“harmonies” by specifying several pitches, or apply pitch
shift based on a user specified envelope curve.
Remove DC Offset
This function will remove any DC offset in the audio selec-
tion. A 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 offsets do not affect what you actually hear, but
they affect zero crossing detection and certain process-
ing, and it is recommended that you remove them.
It is recommended that this function is applied to com-
plete audio clips, since the DC offset (if any) is normally
present throughout the entire recording.
Reverse
Reverses the audio selection, as when playing a tape
backwards.
Silence
Replaces the selection with silence.
Stereo Flip
This function works with stereo audio selections only. It al-
lows you to manipulate the left and right channel in various
ways.
Time Stretch
This function allows you to change the length and “tempo”
of the selected audio, without affecting the pitch.
Hitpoints
This submenu relates to Cubase AI’s special Hitpoint de-
tection functions. This is a special feature that detects
transient attacks in audio material and adds a type of
marker, a “hitpoint” at each attack. Once the hitpoints
have been correctly set, you can slice up the file which
amongst other things enables you to change the tempo
without affecting pitch.
