28
- : A brickwall limiter is used to ensure an audio signal does not
29

30
- is set to the threshold value. This is used in the mixing engine to
31
- ensure 16-bit integers do not exceed their maximum value and wrap
32
- around (which adds ugly sounding distortion). It is important to set
33
- sound and track volume levels properly in order to avoid the
34
- clipping that brickwall limiting adds when mixing signals that are
35
- too loud.
