The effect is intended to be used as a master insert effect for mastering and enhancement. It processes a complete mix, not a single track.
The usual use is:
1) Mix down your track to a stereo wav or an mp3 or select a mixed song for restauration
2) Load the track to wavelab or any other host
3) Load akustix as an insert effect
4) Select a preset (for example general purpose light or medium)
5) Listen to it carefully
6) If you can hear artefacts use a less aggressive setting
7) Compress the track carefully and realease your new CD
