Editing Audio editing software (section)

=== Limitations of non-destructive (real-time) editing ===
*The waveform may not show the effect of processing until the audio has been rendered to another track.
*The number of effects that may be applied is limited by the available processing power of the computer or editing hardware. In some editors, this may be mitigated by rendering to another track.
*It may not be possible to have an effect only on part of a track. Applying a real-time effect to part of a track usually requires that the effect is set to turn on at one point and turn off at another.
*In multi-track editors, if audio is copied or moved from one track to another, the audio in the new track may sound different from how it sounded in the original track as there may be different real-time effects in each track.
*In some applications, mixing down or exporting the edited audio may be slow as all effects and processing need to be applied.
