Invert Phase
This turns the signal “upside down”, which is the same as inverting the
phase by 180°. No settings are needed for the operation.
There is no audible change when you invert the phase of a mono signal.
However, if one channel in a stereo pair is out of phase with the other, this
will lead to artifacts such as a drop in the bass register and a “blurred”
stereo image.
The most common use for this function is therefore to fix a stereo record-
ing where one of the channels has accidentally been recorded out of
phase with the other.
Reverse
This function reverses the selection, as if playing a tape backwards. No
settings are needed.
Eliminate DC Offset
This function removes a problem that most often appears due to mis-
matches between various types of recording equipment.
This function should be applied to whole files, since the problem is normally
present throughout the entire recording.
A DC offset is when there is too large a DC (direct current) component in
the signal. If the DC offset is really bad, it can be visible as the signal not
being visually centered around the “zero level axis”. However, the DC off-
set can be significant without actually being seen.
A wave with a serious DC offset
A DC offset is problematic for two reasons:
