Sound FX
Key Shifter
When activated by clicking the Enable button, this effect changes the
pitch of a digital audio file as it plays—which is very useful to play or
sing along with a song in a different key than the original. Note that
this effect does not alter the original file, it only alters the audio in real-
time as it plays. Moving the slider to the left (-) will drop the pitch,
while moving it to the right (+) will raise the pitch.
Center Canceller
When activated by clicking the Enable button, the level of sounds that
are panned in the center of a stereo signal are reduced. Since many
songs place the voice in the center, the effect is essentially a “voice
canceller”, that may be used to remove any signal panned to the center
of the mix, including vocals. Note that this effect only works on digital
inputs and does not work on analog signals, such as the line input.
Since the effect operates by subtracting the left and right stereo signals,
any sound that’s in both the Left and Right channels (i.e. panned to the center) will be
reduced. When the slider control is in the far left position, there will be no alteration in the
sound. As it is moved to the right, the center signal is attenuated.
⇒ Environments should be disabled when using the Voice Canceller feature.
