Editing Audio editing software (section)

===Limitations of destructive editing===
*Once an effect has been applied, it cannot usually be changed. This is usually mitigated by the ability to "undo" the last performed action. Typically a destructive audio editor will maintain many levels of "undo history" so that multiple actions may be undone in the reverse order that they were applied.
*Edits can only be undone in the reverse order that they were applied (undoing the most recent edit first).
