An approximation of the DC offset of the waveform can be obtained by
running the Statistics function under the Tools menu. For example, if a DC
offset of 100 exists, then you should apply a -100 DC offset to cancel out the
existing offset.
COMPUTE DC OFFSET FROM FIRST 5 SECONDS ONLY (ON/OFF)
When this option is enabled, only the first 5 seconds of a sound file are
analyzed when measuring the DC offset. The only time that 5 seconds is not
sufficient is if a long fade-in or mute has been applied at the beginning of
the file.
FADE
Use a fade to vary the volume of a sound file over time.
GRAPHIC FADE
The Graphic Fade dialog allows you to draw a fade envelope that will be applied
across the current data selection. Up to 16 envelope points are allowed.
Draw the envelope by pulling the small square boxes (drag points) up or down.
The envelope default setting locates the drag points in the upper corners of the
wave display (100%).You can create a new drag point by left-clicking on any
point of the fade envelope. To delete a drag point, single-click on it with the
right mouse button, or double-click on it with the left mouse button. Once
you have finished with the envelope, press the OK button to apply the fade.
SHOW WAVE
Select this option to draw the current selection’s waveform on the envelope
graph.This is done automatically if the selection is small. For stereo files, you
also have the option of displaying the left, right, or a mix of the two channels.
RESET ENVELOPE
Press this button to return the fade envelope to its default shape.
IN
Use this command to linearly fade a selection from a volume of 0 dB to a
volume of -Inf.
